Visible Light
Light Transmittance (LT) is the proportion of visible light at nearnormal incidence that is transmitted through the glass.
Light Reflectance (LR) is the proportion of visible light at nearnormal incidence that is reflected by the glass.
Colour Rendering Index (Ra) expresses the colour renderingproperties of glass in transmission.

Solar Energy
Glass transmits solar radiation from the sun by three mechanisms:reflection, transmission and absorption, which for solar controlpurposes are defined in terms of the following parameters:
Direct Solar Energy Transmittance (ET) is the proportion of solarradiation at near normal incidence that is transmitted directlythrough the glass.
Solar Energy Reflectance (ER) is the proportion of solar radiation atnear normal incidence that is reflected by the glass back into theathmosphere.
Solar Energy Absorptance (EA) is the proportion of solar radiationat near normal incidence that is absorbed by the glass.
Total Solar Energy Transmittance (TET), also known as g valueor solar factor, is the fraction of solar radiation at near normalincidence that is transferred through the glazing by all means. It iscomposed of the direct transmittance, also known as the short wavecomponent, and the part of the absorptance dissipated inwards bylongwave radiation and convection, known as the longwavecomponent. The proportions of the absorbed energy that aredissipated either inside or outside depend on the glazingconfiguration and the external exposure conditions.
Selectivity index S: light to heat ratio (S = LT / TET).
The solar control mechanism is illustrated in Figure 1.
The solar radiant heat admission properties of glasses can becompared by their shading coefficients.
11Glass Handbook 2010
The Total Shading Coefficient (TSC) is derived by comparing theproperties of any glass with a clear float glass having a total energytransmittance of 0,87 (such a glass would have a thickness of about3 mm). It comprises a short wavelength and long wavelengthshading coefficient.
The Short Wavelength Shading Coefficient (SWSC) is the directenergy transmittance divided by 0,87.
The Long Wavelength Shading Coefficient (LWSC) is the fractionof the absorptance released inwards, again divided by 0,87.
Thermal Insulation
Heat loss is quantified by the thermal transmittance or U-value (U).The U-value, usually expressed in S.I. units (Système Internationaled’Unités) of W/m²K, is the heat flux density through a givenstructure divided by the difference in environmental temperatures oneither side of the structure in steady state conditions. It is moregenerally referred to as the rate of loss of heat per square metre,under steady state conditions, for a temperature difference of oneKelvin (or degree Celsius) between the inner and outer environmentsseparated by the glass, or other building element.

1.0 Solar Control
Glass Handbook 2010 15

16 www.pilkington.com
Solar control is a key issue in terms of energy saving. In hotconditions or for buildings with high internal loads, solar controlglass is used to minimise solar heat gain by rejecting solar radiationand help control glare. In more temperate conditions, it can be usedto balance solar control with high levels of natural light.
The topic of air-conditioning is a major concern to buildingdesigners and architects. Often, more energy is used to operate air-conditioning systems during the summer months than to heat thebuilding in winter thereby increasing the carbon footprint. It istherefore essential to improve the energy efficiency of buildingsduring the summer as well as in the winter.
Note: The potential for solar control glass to cut CO² emissions frombuildings has been analysed by the Dutch scientific institute TNO in astudy undertaken for Glass For Europe. The study concludes thatbetween 15 and 80 million tonnes of CO² emissions annually - roughlybetween 5% and 25% of the EU's target - could be saved by the year2020 by optimal use of solar control glass. Reference: “Impact of SolarControl Glazing on energy and CO² savings in Europe” (TNO Report2007-D-R0576/B by TNO Built Environment and Geosciences, Delft,The Netherlands). www.glassforeurope.com.
In cold weather conditions, our low-emissivity glass reduces heatloss while allowing high levels of valuable free solar gain to heatbuildings without significant loss in natural light. However, unlesscombined with solar control, in the summer it can becomeuncomfortably hot. The correct choice of glass can help to reduce thecapital outlay, running costs and associated carbon emissions of abuilding throughout the year.
Given the variety of building designs and climatic conditions and thedifferent levels of exposure to solar radiation during the year, thechoice of glass must be able to protect the inside of the building toensure maximum comfort, minimise energy consumption, guaranteesafety and, not least, provide the optical and aesthetic qualities thatsatisfy the designer.
Solar Control
17Glass Handbook 2010
We are continually innovating and developing products that satisfy thefull range of architectural requirements. Over the years we havedeveloped a wide range of energy management solutions for large andsmall glazed areas on all types of building.
Our innovative solar control products cover the whole range:
● from the highest performing, off-line coated, solar control andlow-emissivity products within the Pilkington Suncool™ range;
● through on-line environmental control glasses that combine good performance solar control with low-emissivity such as Pilkington Eclipse Advantage™;
● to low-performance, body-tinted glass in the Pilkington Optifloat™
Tint range;● and even to solar control glass combined with the revolutionary,
self-cleaning Pilkington Activ™.
In addition to the above ranges our solar control range can be usedwith many other Pilkington solutions, to achieve countless benefitsin terms of safety, functionality and cost-efficiency.
How it works? – Glass controls solar heat radiation by the threemechanisms: reflection, transmission and absorption, which for solarcontrol purposes are defined in terms of the following parameters:Direct transmittance – the proportion of solar radiation transmitteddirectly through the glass.Reflectance – the proportion of solar radiation reflected back intothe atmosphere.Absorptance – the proportion of solar radiation absorbed by theglass.Total transmittance (also known as g value or solar factor) – theproportion of solar radiation transmitted through the glass by allmeans. This is composed of the direct transmittance and that whichis absorbed by the glass and reradiated inwards.

Further parameters given to glass are as follows:
Light transmittance – the proportion of the light that is transmittedby the glass.Light reflectance – the proportion of the light that is reflected by theglass.Total shading coefficient – the ratio between total solar heattransmittance of the glass and that of a single 3 mm thick clear floatglass.Shortwave shading coefficient
Longwave shading coefficientLWSC = TSC – SWSC
Total shading coefficient

Pilkington EverGreen™
Tinted solar control glass
DescriptionPilkington EverGreen™ establishes new standards of quality,aesthetics and performance for green body-tinted glass. Pilkington EverGreen™ glass offers good solar controlcharacteristics and responds to the demand for high lighttransmittance without the use of a surface coating. Its solar controlproperties and colour densities vary with each available thicknessso that glass with properties appropriate to a particular applicationcan be chosen.
ApplicationsPil king ton EverGreen™ is ideally suited to climates or conditionswhere energy costs for cooling are a consideration. Pil king ton EverGreen™ absorbs much of the sun’s heat and UV rayswhile still letting through a high level of daylight. Where a safetyglass is required, Pilkington EverGreen™ can be specified astoughened or laminated glass.Due to its high solar heat absorptance, Pilkington EverGreen™ maybe subject to thermal breakage. The risk of thermal breakage mayoccur on façades exposed to the sun, and in situations where hightemperature differences across the glass pane are expected. In suchcases it is advisable to specify toughened or heat strengthened glass.
Features and benefits● Improved solar control performance compared to traditional tinted
float glass, reducing the need for air-conditioning.● Solar control performance and colour density vary with the
thickness.● Refreshing soft green colour, offering a crisp, clean view of the
outside.● High daylight transmittance, reducing the need for artificial
lighting.● Low internal and external reflection.● Low UV transmittance.● Additional thermal insulation performance when combined in an
insulating glass unit with a low-emissivity glass.
39Glass Handbook 2010
Pilkington EverGreen™
● Easy to handle and process. ● Can be laminated, toughened, bent and enamelled using standard
techniques. ● Can be used in monolithic form or incorporated in insulating glass
units, and has an unlimited shelf-life. ● Available in 6 mm thickness.● Satisfies the requirements for harmonised European Norm EN 572.

Pilkington Optifloat™ Tint
Body tinted solar control glass
DescriptionA range of low solar control performance uncoated body-tintedglass, with low light reflection and high energy absorption.
Please note that in all body-tinted glass products, the properties andcolour density vary with the thickness; this needs to be consideredwhen designing façades where colour uniformity is aestheticallyimportant. All of the body-tinted glasses can be toughened orlaminated and/or incorporated into insulating glass units.
ApplicationsPil king ton Optifloat™ Tint glass products can be used wherever a coloured glass without surface coating is required for visual appealor where a degree of solar control performance is necessary toimprove or control the internal environment of the building. Wherea safety glass is required, they can be specified as toughened orlaminated glass. Due to its high solar heat absorptance, Pilkington Optifloat™ Tintmay be subject to thermal breakage. The risk of thermal breakagemay occur on façades exposed to the sun, and in situations wherehigh temperature differences across the glass pane are expected. Insuch cases it is advisable to specify toughened or heat strengthenedglass.Designed to improve conditions within buildings by reducing glare,solar radiation and heat transfer into the building, they also reduceUV radiation and offer improved privacy, when compared with clearglass.
Features and benefits● Solar control performance, reducing the need for air-conditioning.● Solar control performance and colour density vary with the
thickness.● Available in a choice of colours (Green, Blue-Green, Bronze and
Grey), offering flexibility for original and innovative architecturaldesign even where low reflection is required.
● Subdued colour range, complementing other building materialsand natural surroundings.
43Glass Handbook 2010
Pilkington Optifloat™ Tint
● Low to high light transmission.● Low internal and external reflection, reducing uncomfortable glare
from the sun, and offering improved privacy compared to clearglass.
● Can reduce UV radiation.● Additional thermal insulation performance when combined in an
insulating glass unit with a low-emissivity glass.● Can be laminated, toughened, bent and enamelled using standard
techniques.● Can be used in monolithic form or incorporated in insulating glass
units, and has unlimited shelf-life.● Available in a wide range of sizes from 3 mm to 10 mm (thickness
depending on the colour). ● Satisfies the requirements for harmonised European Norm EN 572.

Pilkington Reflite™
Pyrolytic on-line coated reflective solar control glass
DescriptionA range of medium solar control performance on-line coated clear orbody-tinted glass, with low light transmittance and medium lightreflectance.Pilkington Reflite™ may be used in single glazing applications (withcoating on surface #2), as well as in insulated glass units. They canalso be laminated, heat strengthened, toughened and curved (or bent)using standard techniques. Pilkington Reflite™ can be used in a wide range of residential andcommercial applications.
Due to their high solar heat absorptance, Pilkington Reflite™ may besubject to thermal breakage. The risk of thermal breakage may occuron façades exposed to the sun, and in situations where hightemperature differences across the glass pane are expected. In suchcases it is advisable to specify toughened or heat strengthened glass.
Features and benefits● Medium solar control performance, reducing the need for air-
conditioning.● Attractive colours (Clear, Arctic Blue, Emerald Green and Bronze)
providing a solution for a wide variety of design requirements.● Colour stability whether toughened or annealed.● Medium reflectivity providing privacy whilst still allowing a clear
view to the outside.● Durable pyrolytic on-line coating easy to handle and process,
providing low cost solution with high visual impact.● Can be laminated, toughened, bent and enamelled using standard
techniques.● Can be used in monolithic form or incorporated in insulating glass
units, and has unlimited shelf-life.● Additional thermal insulation performance when combined in an
insulating glass unit with a low-emissivity glass.

● All colours available in 4 mm, 5 mm, 6 mm and 8 mm.● Available in sizes 3210 x 2250 mm and 3048 x 2134 mm.*
* Other sizes may also be available against specific orders in the future.

The full Pilkington Suncool™ range and recommended off-line coatedspandrels are shown below.
* Due to its low reflection, the appearance of Pilkington Suncool™ 70/40 is dominated by
the transmission. However Pilkington Spandrel Glass Coated E200 can be offered as a
spandrel solution for Pilkington Suncool™ 70/40 when the colour match is not expected to
be perfect.
** Pilkington Spandrel Glass Coated E200 is the recommended solution for
Pilkington Suncool™ 70/35 and Pilkington Suncool™ 66/33. Whilst not a perfect colour
match this is the most harmonising offering in comparison to an enamelled spandrel
solution.
*** Pilkington Spandrel Glass Coated E140 is the recommended solution for
Pilkington Suncool™ 40/22. Whilst not a perfect colour match this is the most
harmonising offering in comparison to an enamelled spandrel solution.
As with all spandrel constructions, it is strongly advised that the customer conducts a
visual ‘mock-up’ test to ensure an acceptable match.

ApplicationsPilkington Suncool™ can only be used in insulating glass units.Designed to achieve optimum performance in large glazed areas,Pilkington Suncool™ products are suitable for commercial andresidential applications that demand high light transmissionproperties. The high selectivity index (light-to-heat ratio) combinedwith outstanding thermal insulation makes the range ideally suitedfor large areas of glazing, where the need is to control solar gainswithout significantly reducing the internal light levels. Where a safety glass is required, Pilkington Suncool™ can bespecified as toughened or laminated glass. Toughened or heatstrengthened glass should also be specified in applications wherePilkington Suncool™ may be at risk of thermal breakage.
Features and benefits● Superior solar control performance with the highest level of
thermal insulation (U-value down to 1,0 W/m2K in a doubleinsulating glass unit with 90% argon filled), reducing the need forcooling and heating the building.
● High selectivity index (light transmittance divided by total solarheat transmittance), offering low solar gains without significantlyreducing the internal light levels.
● Wide choice of colours and appearances, providing solutions forthe most demanding designs.
● Range of light transmission and reflection.● Can only be used in insulating glass units; argon gas filling can be
used to achieve higher thermal insulation.● Can be enhanced when combined with other Pilkington products
to provide additional benefits such as self-cleaning, noise control,safety or security properties.
● Can also be combined with Pilkington Optiwhite™ for improvedlight and solar transmittance properties.
● Harmonising spandrel panels available, allowing freedom indesign of complete glass façades.
● Available in 6 mm, 8 mm and 10 mm thickness in annealed andtoughened form (4 mm available in some products, 12 mm may beavailable on special request).

Low-emissivity
Advances in low-emissivity (low-e) glass technology have madewindows an essential contributor to energy conservation andcomfort, minimising heat loss and internal condensation.The measure of heat loss is usually expressed in terms of U-value,which is the rate of heat loss in Watts per square metre per degreeKelvin temperature difference between inside and outside (expressedas W/m²K). The lower the U-value, the better the insulation of theproduct.
How it works – Effectively, low-emissivity glass will reflectenergy back into a building, to achieve much lower heat loss thanordinary float glass. Additionally, different types of low-emissivityglass allow different amounts of passive solar heat gain whichhelps reduce heating requirements and costs, especially in coldermonths.

Solar energy enters the building mainly as shortwave radiation but,once inside, it is reflected back by objects towards the glass as long-wave radiation. Low-emissivity glass has a coating that allows thetransmission of the sun’s shortwave radiation at a much higher ratethan longwave radiation (from the heaters, electrical equipment andoccupants in the room), providing an effective barrier to heat loss.
Note: The potential for low-e glass (double and triple glazing) to cut CO²emissions from new and existing buildings has been analysed by theDutch scientific institute TNO in a study undertaken for Glass ForEurope. Up to 90 million tonnes of CO² emissions could be savedannually by 2020 if all Europe’s buildings (existing and new residentialand non-residential buildings) were fitted with double-glazed low-einsulating glass units. An additional 7 million tonnes of CO² emissionscould be cut thanks to the greater use of triple-glazed low-e insulatingglass units for new buildings, where appropriate. Reference: “Potentialimpact of Low-Emissivity Glazing on energy and CO² savings inEurope” (TNO Report 2008-DR1240/B by TNO Built Environmentand Geosciences, Delft, The Netherlands). www.glassforeurope.com.
To maximise energy efficiency all year round, often the ideal glazingsolution balances both solar control and low-emissivity performance.Our products offer two ways in which this can be achieved:
● by applying a single product which provides both solar control andlow-emissivity in an insulating glass unit,
● by using both a solar control product and a separate low-emissivityproduct within an insulating glass unit.
Our low-emissivity range covers all levels of requirements:
● from on-line products such as Pilkington K Glass™,● to extremely low U-value off-line solutions in the
Pilkington Optitherm™ range,● through to Pilkington Suncool™ Pilkington Solar-E™ and Pilkington
Eclipse Advantage™ which provide both low-emissivity and solarcontrol properties in a single product.

Pilkington Optitherm™
Off-line coated high performance low-emissivity glass
DescriptionPilkington Optitherm™ S1 and Pilkington Optitherm™ S3 are highquality clear glasses with specially formulated off-line low-emissivity coatings applied to one surface after glass manufacture.The effect of the low-emissivity coating is to reflect the longwavelength energy (generated by heating systems, lighting andbuilding occupants) back into the building. However, the transparentcoating still permits the transmission of short wavelength energyoriginating from the sun. This solar energy is absorbed by theinternal surfaces of the building and re-radiated at the longerwavelengths that are then reflected by the coating into the building.The visual appearance of Pilkington Optitherm™ S1 andPilkington Optitherm™ S3 is almost identical to that of ordinaryclear glass. As the coating is transparent and neutral in colour, itseffect on light transmission and reflection is barely perceptible.
ApplicationsPilkington Optitherm™ S1 and Pilkington Optitherm™ S3 canonly be used in insulating glass units. They are popular low-emissivity glasses because of their neutral colours, their high light transmissions and their excellent thermal insulationcharacteristics. They can be used from the smallest installation tothe most prestigious curtain walling applications – anywherewhere there is concern for reduced energy consumption and heatloss. Pilkington Optitherm™ S1 has a higher performance low-emissivity coating than Pilkington Optitherm™ S3, to furtherreduce heat loss through the unit for more demandingapplications. Available in 3, 4, 6, 8, 10 and 12 mm thicknesses,they are often used in combination with other environmentalcontrol glasses. Pilkington Optitherm™ S1 and PilkingtonOptitherm™ S3 cannot be toughened or laminated after coating.However, where a safety glass is required, the coatings can beapplied to toughened or laminated glass.
For safety applications, Pilkington offers Pilkington Opti therm™ S3 Pro T.This glass has to be toughened and its colour is matched toPilkington Opti therm™ S3. After toughening the product has similartechnical performance to Pilkington Opti therm™ S3.

3.0 Fire Protection
92 www.pilkington.com
Fire Protection
The wide range of modern functional glazings now available hasopened up remarkable scope for creative design in today'sarchitecture. Transparent design from façades and roofs rightthrough to the centre of the building is no longer a vision, it is reality.
State-of-the-art glazing can now be used in high performance designs to provide a protected, yet comfortable and versatile buildingenvironment, founded on daylighting, brightness and clear vision,replacing solid roofs, doors and partitions which block out views andnatural light. Our fire protection range of products, Pilkington Pyrostop®
and Pilkington Pyrodur®, combine fire resistance and designflexibility, for peace of mind, elegant and functional buildings.
New and existing buildings according to regulations in force shouldprovide suitable level of fire safety. The ordinary clear float glasswidely used in buildings is not resistant to fire at all. It breaks attemperature difference equal to about ΔT 40°C. Ordinary laminatedsafety glass is also not resistant to fire – the glass breaks as quickly asclear float. Furthermore, at temperature of about 250°C, when thePVB foil melts and fails to retain the glass fragments, the glasscollapses. Whilst standard toughened glass is more resistant to hightemperatures, it generally cannot survive temperatures higher thanabout 300-350°C.

foam
The reaction of Pilkington Pyrostop® and Pilkington Pyrodur® in case of fire.
Fire Protection
That is why it was necessary to introduce products that couldwithstand typical temperature of fire of 1000°C, and additionally inthe event of fire, would be able to give people the maximum amountof time for safe escape. Pilkington Pyrostop®and Pilkington Pyrodur®meet these criteria.
Pilkington Pyrostop® and Pilkington Pyrodur® are clear, multi-layered fire resistant glasses made of clear or extra clear float glass(Pilkington Optifloat™, Pilkington Optiwhite™), laminated withtransparent intumescent interlayer. When exposed to fire, the panefacing the flames fractures but remains in place, and the interlayerimmediately foams up to form a thick, resilient and tough insulatingshield that absorbs the energy of the blaze. This takes place at onlymodest temperatures around 120°C, such that protection is providedright from the early stages of a fire. The resilient sandwich structureof Pilkington Pyrostop® and Pilkington Pyrodur® ensures that theystay in place and continue to act as an insulating fire-resistant wallfor the required time periods, as defined in the standard approvalstests.
Pilkington Pyrostop® and Pilkington Pyrodur® have been tested inmore fire doors, fire protection framing and façade systems than anyother fire-resistant glass product, covering vertical, horizontal andinclined glazing situations.
Definitions:Integrity (class E)The ability of the system to keep back flames, smoke and hot gases.No flaming on the non-fire side is permitted within the approvedtime classification.
Insulation (class I)The ability of glazed screens or doors to limit the temperature rise onthe non-fire side to an average of no more than 140°C and in any oneposition by no more than 180°C.
Radiation (class W)The ability of the element of construction to reduce the probabilityof transmission of fire as a result of significant radiated heat, eitherthrough the element or from its unexposed surface to adjacentmaterials on the non-fire side.

4.0 Noise Control
Introduction
It could be a Sunday afternoon when you are indoors reading a goodbook, you could be tucked up in bed at night or seated at work tryingto concentrate when you are disturbed by noisy neighbours, traffic ora variety of other unwanted noise. We all suffer from the intrusion ofnoise at some time or another.
With an increasing population density, factory production andtransport, the noise seems to get worse with fewer opportunities toescape. Along with the increase in noise is a growing awareness ofthe effect on health due to the stress caused by everyday soundsintruding into once quiet environments. The trend for the futuresuggests that traffic and noise in general is going to get worse asliving space declines. There is an increasing interest in ways toprotect people from noise to avoid the considerable stress that itcauses and in some cases serious illness.
A considerable amount of work has been done to control noiseintrusion into a building and between adjoining areas, and whilstthis is valuable we want to concentrate on the contribution that thecareful selection of glass has to offer in managing the problem.
Figure 1: Sound spreads out in a similar manner to waves in water.

Noise Control
What is sound?
From a physical point of view, sound belongs in the field of wavephysics / mechanical oscillations. Even 2000 years ago, a Romanarchitect engaged in the construction of amphitheatres used waves inwater to improve his design.
For example, if we strike a tuning fork, we can hear the oscillations,but we cannot see them. These oscillations of the tuning fork aretransmitted to air molecules, which then pass on their oscillations toother air molecules. This behaviour can be demonstrated in water.These oscillations are comparable to a wave in water, with the heightof the wave being a measure of the volume of sound and the numberof waves in time is the frequency of the sound i.e. the more waves,the higher the frequency. Frequency is defined as cycles per secondor Hertz. Hertz is the correct way to describe the frequency or pitchof the sounds and is abbreviated to Hz.
Figure 2: Definition of frequency.
In music, the note A (nearest A above middle C) has a frequency of440 Hz or oscillations per second in concert tuning. If the frequencyis doubled to 880 Hz, the note increases by an octave for equaltempered tuning.
The human ear of a young person can detect frequencies of 20 Hz up to 20,000 Hz and is capable of detecting sound pressures, or to be more precise pressure fluctuations, of between 10-5 Pascals (Pa) =0,00001 (lower limit of hearing) and 102 Pa = 100 Pa (pain threshold)

by passing these on to the brain as a sensation of volume. Withincreased age the range of audible frequency diminishes from bothends of the scale naturally or from hearing damage.
The relationship between the quietest and the loudest noise is a ratioof 1 to 10 million. Since this is very unwieldy, in practice the sound-pressure level, or sound level L for short, is expressed as alogarithmic scale which represents a conversion of the soundpressure into a more convenient measure known as the decibel scale(dB). The normal range extends from 0 dB (hearing threshold) toaround 130 dB (pain threshold). Figure 3 shows a few examples.
Figure 3: Noise source and perception (source: Kuraray, Troisdorf).
There are a variety of ways of creating noise and each noise canproduce different volumes of sound at different frequencies. If weuse aircraft as an example there is a clear difference in the soundmade by propeller driven aircraft, modern fan jets and militaryaircraft. If the volume by frequency is plotted as a graph they wouldlook distinctly different. When trying to defeat noise these variationscan be taken into account and different glass types also work betterat some frequencies than others. By matching the performance of theglass to the noise we can selectively reduce the most annoying

sounds to get the maximum benefit. Anyone living next to a privateairstrip with light aircraft has a very different problem to a neighbourof a military base. The solution to the noise problem will be to use adifferent glass configuration.
Determining the noise level can be done in a number of ways. Forlarge or difficult projects a site noise survey can be commissionedusing acoustic consultants who use sensitive equipment to measureand average noise levels by frequency over a period. These surveysgive precise data on the volume of noise at each frequency that needsto be attenuated. The information is often provided in reports thatbreak the noise down into a table showing octave frequencies, e.g.:
The sound can be measured at the site, close to the noise source or adistance in between. Where site data is not provided an adjustmentcan be made to the sound to allow for distance. The further you areaway from the source the less impact it has.
The noise level is often measured over a period and averaged toremove the disproportionate effect of isolated loud noise that isexceptional like a car horn sounding. A level of noise energy can bedetermined that is an A weighted long term average called the day-evening-night level (Lden). It is the Lden noise level that should be thebasis of the design rather than isolated peaks in sound. Therefore
Example: Decay of noise with distance.
Road traffic noise decreases by approximately 3 dB with doubling of distance atright angles to the road. If, for example, L is the dB noise level at 5 meters, then thedecay follows the pattern:
5 m L dB
10 m (L-3) dB
20 m (L-6) dB
40 m (L-9) dB
80 m (L-12) dB
160 m (L-15) dB

the aim of the design should be to control the general noise ratherthan exceptions otherwise the noise reduction criteria would becomeextreme. For some applications it may be appropriate to use only partof the three periods or a supplementary noise indicator for noise thatonly occurs for a short period of time.
There is sometimes an option with noise measuring equipment torecord the data with an A weighting. Where interior noise limits areset they are often expressed in dB (A) lub LAeq. The A weighting is an adjustment to the noise at each frequency that follows astandardised curve. The A weighting is a recognition that the humanear does not react to the same volume at each frequency equally i.e.some frequencies seem louder than others even though they arebeing delivered with the same energy. It is important that the humanreaction to noise is considered rather than making decisions basedupon the sensitive instruments that measure sound in an absoluteway.Where a survey is not carried out then there are examples of previoussurveys that allow designers to assume typical noise levels fromcommon sources of noise e.g. road traffic, music, speech, trains,aircraft etc.
Where third octave or octave band information is not provided thereare a range of shorthand expressions used for the noise, typically theRW and Rtra figures may be used to abbreviate the information. Forglass performance the abbreviations are determined by taking plotson a graph of the sound attenuation by frequency and mathematicallycomparing standard curves to then until they are a good fit. The noise reduction at a fixed frequency on the standard curves providesthe RW and Rtra figures.
When the noise level is known the performance of the glass can bematched to get the required level of residual noise. It is importantthat the indices of measurement are matched or in the same scale toensure that the calculation is correct.
For those who like to dig a little deeper
The measured values for 10 mm Pilkington Optifloat™ – 16 mm airspace – 9,1 mm Pilkington Optiphon™* are shown in blue. The* previously known as Pilkington Optilam™ Phon
reference curve specified in EN 717 Section 4 is shown in red. Thisreference curve is now moved downwards in whole dB increments,until the sum of the deviations of the measured values from theshifted reference curve is maximised and less than 32 dB. Only thosemeasured values that are less than the reference values are taken intoaccount. The y-value of this shifted reference curve (green curve inFig. 4) at a frequency of 500 Hz is the sought RW-value, in thisexample 45 dB. Unfortunately, the above-mentioned relationshipbetween the sound-pressure amplitude and the perceived volume isnot as simple as scientists would like it to be because nature hasmade our hearing more sensitive to certain ranges than to others.This means that we perceive a thousand Hz tone as louder than ahundred Hz tone, even though the volume is the same. This propertyof the human ear is taken into account in the shape of the referencecurve.

standardised conditions. As we see, sound insulation is veryfrequency-dependent. To avoid having to work with the completedata set this diagram can be reduced to a single value. Thestandardised procedure is described in the box below. The result is asingle number – in this case RW = 45 dB – which can be used infurther calculations.
The disadvantage of such a single-value specification is that we canarrive at the same result with completely different curve shapes, asshown in Figure 5.
We achieve more expressive single-value specifications if we use“custom-made” reference curves for specific requirements.
Such “special cases” are C and Ctr. They take into account thedifferent frequency spectra of residential and traffic noises and thusmake it possible to find adequate solutions to the problems inquestion in a simple manner.
The C-value takes into account the noise sources:● residential activities (talking, music, radio, TV),● children playing,● rail traffic at average and high speed,

● motorway traffic > 80 km/h (50 mph),● jet aeroplanes a short distance away,● businesses that emit primarily medium- and high-frequency noise.
The Ctr-value takes into account noise sources such as:● urban road traffic,● low speed rail traffic,● propeller aeroplanes,● jet aeroplanes a long distance away,● disco music,● businesses that emit primarily low- and medium-frequency noise.
Thus, if the planned building is located in a city, right by a main road,the Ctr value is the most suitable. If a building is planned right nextto a motorway, the C value is more appropriate.
Calculation rules
Although the use of the dB scale facilitates nice convenient numbers,it also gives rise to somewhat unusual “calculation rules”. If a noisesource is duplicated then the overall dB value rises by only 3 dB. A ten-fold increase i.e. ten electric fans instead of one, leads to anincrease of only twice as much noise i.e. 10 dB.
To complete the explanation, we should also mention that a halvingof the noise level at the ear is not recognised as a halving of thevolume. In general it is true that:
● a difference of 1 dB is not practically noticeable,● a difference of 3 dB is just perceptible,● a difference of 5 dB represents a clear difference,● a difference of 10 dB halves / doubles the noise.
The different types of sound insulation
Mass
As mentioned above, sound spreads in waves by exciting themolecules of the medium in question so that they oscillate. Due tothis means of transmission, the noise is subject to a naturaldamping – depending upon the mass in question. Expressed

simply: the more mass put between transmitter and receiver, thegreater the damping.
The simplest way of increasing the sound insulation of glass istherefore to use a lot of glass. Thus a 12 mm single pane has an RW
value of 34 dB, whereas the corresponding value for a 4 mm pane isonly 29 dB.
Coincident frequency and asymmetry
If we compare the spectra of 4 mm, 8 mm and 12 mm float glass, we see that each of these spectra has a downturn in the right-handsection.
This fall off in performance at certain frequencies or coincidentfrequencies occurs at the frequency that matches the natural resonantfrequency for the product. The so-called coincident frequency fg ismaterial specific and dependent upon thickness for glass. As a ruleof thumb:

119Glass Handbook 2010
Noise Control
According to this formula, fg is 3000 Hz for 4 mm float glass, 1500 Hz for 8 mm float glass and 1000 Hz for 12 mm float glass,which corresponds very well with the spectra in Figure 6.
To overcome this we can mix the thicknesses of glass panes in aninsulating unit structure so that when one pane is at its coincidentfrequency the other is not and continues to defeat the sound. Suchasymmetric structures can thus significantly reduce the downturn inthe coincidence range, as shown in Figure 7. A 30% difference inthickness is desirable. Not only does this reduce the dip but it alsoshifts it up the scale which is beneficial as the higher the frequency,the more effective the glass becomes at reducing the overall noiselevel.
Gap between panes / gas fillings
Another method for controlling the transmission of noise is to varythe distance between the panes of glass. With conventional insulatingglass units the gap between the panes is limited to maintain theoptimal thermal performance and the size ofthe gap is not largeenough to significantly improve the acoustic performance. Withsecondary glazing there is an opportunity to have relatively largegaps and an airspace of over 60 mm starts to provide realimprovements in performance. The space between the panes can alsobe lined with acoustic tiles to enhance the benefit.

Gas filling the space between panes of an IGU has a marginal effectand there is no practical improvement in using argon gas. Due to thedensity of krypton a small benefit can be gained in acousticperformance of up to 1 dB. Sulphur hexafluoride (SF6) could be usedfor sound insulation simply because it is so heavy, however, this gashas two disadvantages. Firstly it worsens the thermal insulationvalue and secondly this gas has a CO2 equivalent of 22.800 and thusmakes an extremely large contribution to the greenhouse effect. Forthese two reasons, the use of SF6 gas is banned throughout large parts of Europe.
Decoupling / damping
We have said that the thickness of glass helps and varying the glassthicknesses in an insulating unit is a useful method of improvingnoise reduction. Adding mass to the product or having large air gapsmay also be undesirable for reasons of weight and space.Fortunately there are ways of improving the noise reduction ofrelatively thin panes of glass by introducing a damping effect withinthe glass. By laminating the glass with ordinary PVB interlayer wecan reduce the fall off in performance due to the coincidentfrequency and shift the frequency at which the downturn occurs.Adding a Pilkington Optilam™ product to the construction can havea marked improvement particularly where the noise level would behigh at the coincident frequency for a monolithic glass. Insulatingglass units can provide very good results with a mixture of monolithic(Pilkington Optifloat™) and Pilkington Optilam™ glass types.
For higher specification requirements there is Pilkington Optiphon™.These products use special interlayers in a laminate that furtherdecouple the two panes of glass whilst still providing the impactsafety of laminated glass. If you look at the curve profile forPilkington Optiphon™ you will see that the fall off in performance atwhat would have been a coincident frequency is almost eliminated.The correct grade of product can be chosen to match the soundprofile to allow superior performance without dramaticallyincreasing the glass thickness. This allows for greater flexibility indesign without compromising other glazing functions.
In the left-hand part of the spectra (Fig. 7) we see a furtherdownturn. This is the so-called resonant frequency. This is the
121Glass Handbook 2010
Noise Control
frequency at which the component as a whole oscillates inresonance and thus transports the sound oscillations particularlywell and insulates poorly.
The sound insulation can be improved by moving the resonantfrequency of the component to another frequency (away from thenuisance frequency or to where the human ear can hear less well).This is achieved by “decoupling” the insulating glass unit, bymaking a pane of glass at the same time dense and soft. This can beachieved by joining two panes of glass either with special (soft)cast-in-place resins or with modern PVB interlayers developedspecially for this application.
Important reminder
The object of selecting the right acoustic product is to make theinternal environment comfortable and free from the stress associatedwith noise intrusion. The level of residual noise is not the same forall locations and national guidelines are produced for mostenvironments. For instance, the background noise in a library shouldbe around 30 dB. Zero noise is undesirable and tends only to befound in an echoic chambers usually reserved for testing. Zero noisecan be an eerie experience as the ear tunes to other sounds thatbecome distracting.The equation as a first guide becomes:
Noise Source – building attenuation = residual noise
Note that the whole building needs to work and that glass alone willnot solve all acoustic problems. Sound only needs a small entry wayto get into a building unlike heat loss or gain, which tends to beproportional to the surface area. For a noise reduction of up to 35 dB provided by the glass the window frame without a ventilatorshould provide similar performance. Above this level, windowsdeveloped for noise reduction need to keep pace with the glassperformance to ensure the combined product is functioning.

To sum up
There are five factors that can be combined, which can positivelyinfluence the sound insulation of an insulating glass unit.1. Glass mass.2. Asymmetric structure.3. Large gap between panes.4. Use of alternative gases.5. Use of Pilkington Optiphon™ special laminated safety glasses or
Cast In Place (CIP) products.
For the higher sound insulation requirements, modern soundinsulating laminated safety glass products such as Pilkington Optiphon™, are becoming increasingly prevalent incomparison to the cast-in-place resin products because RW values ofeven more than 50 dB can be achieved and they can be supplied inlarge sizes. The compatibility of PVB with other materials is wellunderstood and safety benefits such as impact protection / saferoverhead glazing can also be achieved.

Insulating glass units with improved sound insulation
With increasing traffic on the road, rail and in the air, noise insulationhas become a very important topic. It is not a question of it being aluxury anymore it is essential that noise reduction is considered inthe specification of the glazing.Pilkington In su li ght™ Phon is a proven and tested solution to theproblem of noise control.
The enhanced sound insulation of Pilkington In su li ght™ Phoninsulating glass units is made possible through the use of:● panes of varied thickness – a 30 percent difference in thickness is
recommended, e.g. 6 mm and 10 mm;● Pilkington Optilam™, laminated glass, which is produced by
combining two or more glass sheets with one or more PVBinterlayers;
● Pilkington Optiphon™ glass: laminated, sound absorbing glass withhigh acoustic insulation, which uses special foil to yield excellentnoise attenuation parameters.
All above mentioned products can be combined with otherfunctional products such as low-emissivity glass for improvedthermal insulation or solar control glass for better solar controlperformance.

5.0 Safety / Security
133Glass Handbook 2010

Safety / Security
Demanding safety legislation has highlighted the critical areas wheremodern safety glazing must comply with the relevant safetyrequirements. Innovations in the development of Safety/Securityglass has opened up new avenues of design, which allows people tobe protected from personal injury and, in the most extreme cases,protect buildings from various forms of attack.
With this in mind, we have developed a wide range of sophisticatedproducts, in order to meet these ever increasing demands, withoutcompromising on design criteria of natural light and visibility. We arealways at the forefront in further developing the products and theindustry standards, so that personal accident and serious injuriesresulting from glass impact are further prevented or minimized.
What does “Safety” and “Security” mean?
Although Safety and Security are closely linked topics, it is importantto understand the distinction between the two terms, to ensure theright glass is specified.
The term “Safety” is applied to glazing used to reduce the risk ofaccident by impact, fracture, shattering, or in a fire. The term“Security” is applied to glazing, which in addition to “Safety”, is ableto withstand a variety of deliberate attacks such as physical, armed orblast.
Using only the right type of glass is not enough to secure thenecessary resistance to the severe loads. The glass, once impacted,behaves differently in different framing systems, it is thereforeimperative to combine high performance glazing with highperformance framing systems.
The standards
EN 12600 Glass in building – Pendulum test –Impact test method and classification for flat glass
The pendulum impact test is the standard for classifying flat glassproducts by performance under impact and by mode of breakage.Similar in principle to previously used swing bag tests, EN 12600utilises a dual rubber tyre impactor to strike the glass at three dropheights.
The classifications are summarised below.
The classification has three components:
● The first is the class (i.e. 1, 2 or 3) at which the glass has either notbroken or broken safely.
● The second is the mode of breakage defined as:Type A: numerous cracks appear forming separate fragments with
sharp edges, some of which are large – typical ofannealed glass.
Type B: numerous cracks appear, but the fragments hold togetherand do not separate – typical of laminated safety glass.
Type C: disintegration occurs, leading to a large number of smallparticles that are relatively harmless – typical oftoughened glass.
● The third is the highest drop height (i.e. 1, 2 or 3) at which theproduct did not break (e.g. for toughened glass) or where it broke,but no shear or opening bigger than 76 mm in diameter appeared.

EN 1063 Glass in building – Security glazing –Testing and classification of resistance against bullet attack
This specifies performance requirements and test methods for theclassification of bullet resistant glass, based on attack by handguns,rifles and shotguns.
The test consists of 3 shots fired on the vertices of a 100 mmequilateral triangle glass sample with a weapon corresponding to therequired class.
If the glass sample has not been pierced by the shots then therequired class is achieved. Behind the glass sample is an aluminiumwitness sheet. If after the shots have been fired there are someperforations on it, then the resistance class must have the suffix S(splinters), otherwise it is classified NS (no splinters).
These classes of resistance are summarised below.

DescriptionPilkington Toughened Safety Glass is manufactured by subjectingthe final glass size to a heating and cooling treatment which sets uphigh compressive stresses at the surface and balancing tensilestresses in the centre of the glass, which increases glass strength.
The high compressive surface stresses give Pilkington ToughenedSafety Glass its increased resistance to mechanical and thermalstresses. It can, however, break under extreme loads or by severeimpact. When broken, Pilkington Toughened Safety Glass shatters intosmall, blunt-edged fragments, reducing the risk of personal injury.
Most Pilkington glass is available in toughened form.
ApplicationsPilkington Toughened Safety Glass provides an economical andproven solution in any areas of particular hazard where nationalstandards or Codes of Practice specifically require the use of safetyglazing material.Pilkington Toughened Safety Glass can be used, for example, alongpassageways and areas of high pedestrian traffic, in doors andadjacent panels, shower and bath enclosures, balconies, barriers,staircases and other structural glazing applications. It can be used to provide uninterrupted single or double glazed cladding for the whole building. Other applications include frameless shop fronts and entrances, internal partitions, furniture, canopiesgymnasiums and sports arenas.
Features and benefits● Achieves up to Class 1(C)1 according to EN 12600, dependent
upon glass type and thickness.● Up to 3-4 times stronger than ordinary glass of the same thickness,
offering a proven solution to safety and strength concerns.● Can be heat soaked for extra confidence in use.● When broken, it shatters into small, relatively harmless pieces,
reducing the risk of personal injury.● Reduces the risk of thermal stress breakage of glass exposed to
solar radiation.● Conforms to all the requirements of EN 12150-1 and is CE marked
in accordance with EN 12150-2.● Available in a wide range of sizes and thicknesses.
Pil king ton Toughened Safety Glass
All types of Pilkington Toughened Safety Glass will be readilyidentified by the simple use of ‘T’ following the product brandname.To distinguish heat soaked toughened glass from standardtoughened glass, the word ‘Plus’ is used at the end of product name. Examples are given below.

Self-cleaning
Pilkington made a significant step in the glass industry with thedevelopment of Pilkington Activ™ the first dual-action self-cleaningglass. The unique dual-action of the Pilkington Activ™ coating usesthe forces of nature to help keep the glass free from dirt, giving notonly the practical benefit of less cleaning, but also clearer, better-looking windows. The Pilkington Activ™ coating, located on surface#1 of the glass, works in two stages. Firstly, it reacts with naturaldaylight to break down and loosen organic dirt. Secondly, when itrains, instead of forming droplets, the water spreads evenly over thesurface of the glass, forming a thin film and helping to wash any dirtaway, preventing the formation of drying spots and streaks, andhelping the glass to dry very quickly. In installations wherecondensation is a problem, it reduces its visibility and helps it toevaporate more quickly.The Pilkington Activ™ coating works also on cloudy days and duringthe night. During dry spells the glass can be cleaned by simplyhosing it down.
Glass used today in commercial buildings and offices, has to providemultiple functions. A technical profile of large glazed areas mustmeet requirements related to solar control, thermal insulation andnoise control, as well as strict safety regulations. These requirementscan now be combined with self-cleaning properties. Availability ofdual coated products and laminating possibilities allow themanufacture of the glass products that ensure aesthetics, safety,comfort and cost-effective operation of modern buildings, allowingbest cost effective management of buildings.
Dual coating technology is used to combine self-cleaning and solarcontrol properties in one product, ensuring a highly cost effectiveglass combination. Pilkington Activ Suncool™ is manufactured witha Pilkington Activ™ coating on the outside (i.e. on surface 1) and aPilkington Suncool™ coating on the inside (i.e. coating on surface 2).It is used in insulating glass units to enable cost effective buildingmanagement literally from both sides.

In the commercial sector the glass often needs to provide additionalprotection features. To meet these requirements, Pilkington offerstwo product lines of laminated safety glass. Using laminatedPilkington Activ™ glass for façade elements and on glazed roof andsloping areas which are difficult to access, both safety and self-cleaning can be assured.The same applies to the combination of the self-cleaning propertieswith noise control of the façade. Functional glass, such as Pilkington Activ Optiphon™ allows a significant decrease in costs ofwindow cleaning, and at the same time, it has an increased soundreduction index (Rw).
Pilkington Optitherm™ S3 low-emissivity coating, usually used onsurface #3 in insulating glass units, is sometimes difficult orimpossible to apply on some glass types. However, dual coatedPilkington Activ Optitherm™ S3 provides self-cleaning and goodthermal insulation for insulating glass units with thick bullet-resistant or textured glass.

Pilkington Ac tiv Suncool™ is a range of dual coated productsincorporating self-cleaning, solar control and thermal insulationproperties. The external self-cleaning coating breaks down theorganic dirt, and rain water washes any loosened dirt away. Theinternal solar control and low-emissivity coating reflects shortwavelength solar radiation out of the building, as well as longwavelength heat radiation (generated by heating systems, lightingand building’s occupants) back into the building.Pilkington Ac tiv Suncool™ effectively reduces solar heat gain, at thesame time providing high level of light transmittance and aestheticappearance.
We have developed a range of Pilkington Spandrel Glass productsfor use with Pilkington Activ Suncool™ solar control glass to ensurecontinuity in the aesthetic design of façades. Pilkington SpandrelGlass Coated is available in thicknesses 6 mm, 8 mm and 10 mm in toughened form. Maximum size of such spandrels is 2500 x 4500 mm.

expected to be perfect.
** Pilkington Spandrel Glass Coated A200 is the recommended solution for
Pilkington Activ Suncool™ 70/35 and Pilkington Activ Suncool™ 66/33. Whilst not a
perfect colour match this is the most harmonising offering in comparison to an enamelled
spandrel solution.
*** Pilkington Spandrel Glass Coated A140 is the recommended solution for
Pilkington Activ Suncool™ 40/22. Whilst not a perfect colour match this is the most
harmonising offering in comparison to an enamelled spandrel solution.
As with all spandrel constructions, it is strongly advised that the customer conducts a
visual ‘mock-up’ test to ensure an acceptable match.

Glass Systems
Glass can be used to create building interiors which connectoccupants with the external environment, combining unbroken viewsof the surrounding nature and high level of natural light with thecomfort and safety of the internal environment.
This section present two of our attractive and practical glass systems,which will allow you, for example, to transform yards into cosyinteriors, enclose private and public outdoor areas under glass roofsand build stunning glass façades.
Our two major glass systems, Pilkington Planar™ andPilkington Profilit™ are developed for use in glass façades, walls orroofs, and also for internal glazing applications. Our Pilkington specialists and accredited installers can provide allthe support that architects and designers require during theirplanning and design process.
185Glass Handbook 2010
Pilkington Planar™
The ultimate structural glazing system
DescriptionA structural glazing system that provides a flush glass surface, byutilising stainless steel fittings housed in countersunk holes to fix theglass façade back to the structure, instead of using the moreconventional framed systems. The result is a fully engineered systemwith the minimum of structure and the maximum visual clarity. The exterior glass used in all Pilkington Planar™ systems is normally10, 12, 15 or 19 mm thick Pilkington Optifloat™ heat soakedtoughened glass. A silicone seal between adjacent panels providesweatherproofing. Pilkington has been at the forefront of structuralglass testing and design for over 40 years. The fixture holes are acritical feature, subject to constant investigation and testing becauseof the stresses induced locally by wind or snow loading, or by theweight of the façade. Positive and negative wind loads as well assnow loads must be resisted by the system and transferred throughthe fixing locations. The system uses a combination of thickness ofglass, panel size and number of fixings to accommodate for a varietyof loads. Pilkington Planar™ system has given architects the freedomto create the stunning glass buildings and canopies that are such afeature of modern cityscapes.
Glass types used within Pilkington Planar™ systems:● Single glass – flat and curved.● Single laminated safety glass.● Pilkington Planar™ Integral.● Insulating glass units.● Laminated insulating glass units.● Triple insulating glass units – Pilkington Planar™ Triple.
Please note that Pilkington Planar™ can incorporate most Pilkingtonglass types, including our the range of solar control, low-emissivity,screen printed glass as well as our Pilkington Activ™ self-cleaningglass.

Solar controlPil king ton Pro fi lit™ Antisol reduces the total solar energytransmittance (g-value) of the glazing.Although the Pil king ton Pro fi lit™ Antisol coating is bronze incolour, high visible light transmittance can be maintained.
SafetyThermally toughened profiled glass Pilkington Pro fi lit™ T isspecially designed to satisfy increased safety requirements withincommon areas of public buildings. This product variant providesgreater mechanical strength compared to its annealed version,allowing the creation of large surfaces that are bright whilst alsomeeting all safety requirements. In addition it allows for longerinstallation lengths in comparison with standard Pilkington Pro fi lit™.Heat soaked thermally toughened glass is available upon request.
8
Pilkington Profilit™
DecorationThermally toughened and colour coated Pilkington Pro fi lit™ T Coloris a profiled enamelled glass available in a wide range of colours,that gives architects new design possibilities. As the glass istoughened, it also meets higher safety requirements.
Noise controlNoise ranks among the most unpleasant emissions. Thepsychological and physical strain resulting from noise is acontinuous hazard to human health.The use of Pilkington Pro fi lit™ glass reduces the level of externalnoise to a level that is safe for the human ear. A double glazedinstallation with the padding profiles no. 165 and 166 achieves asound reduction of 38 - 41 dB. Triple glazing can be used to achievea sound reduction of 55 dB.
ApplicationsPilkington Pro fi lit™ can be used in interior or exterior applications.The "U-shaped" channels can be installed either vertically orhorizontally. The glass is available in a variety of colours andtextures with varying translucency, allowing for the passage ofnatural light without the loss of privacy. Pilkington Pro fi lit™ isenergy efficient, provides excellent sound reduction and is one of themost cost-efficient glass wall systems available. It can be singleglazed for interior use or dual glazed for exterior applications.

Special Applications
Our special applications section includes products with specificproperties.Pilkington Optiwhite™ – is an extra clear low iron float glass whichcan be used as a final product, in insulating glass units or as a by-product for manufacture of other special glass products. It is alsoused in the fast developing solar energy sector.
Pilkington Mirropane™ is used as a one-way vision mirror forundetected surveillance. This type of glass is used in areas whichneed to be observed or where people need to be prevented fromlooking in, for example in police stations, customs halls, hospitals,warehouses, computer installations and banks.
Pilkington TEC Glass™ is a range of low-emissivity glasses with anelectric conductive coating of special qualities. Pilkington TEC Glass™
is also used in white goods applications such as fridge and ovendoors, where high insulation is required. In its toughened version, itis used for direct electrical heating, which uses an electric currentpassing through the coating. Because the coating conductselectricity, static electricity is conducted from the coated side. Wemanufacture various types of Pilkington TEC Glass™ with differentresistance levels. The glass is neutral and transparent likeconventional float glass and has high light transmission. It can becurved, toughened and screen printed.If you are interested to know more about these products pleasecontact our Technical Advisor.

Pilkington Mirropane™
High reflective coated glass for one-way vision
DescriptionAn on-line coated glass product developed for use as a one-way mirrorwhere total clear vision is required and specific lighting conditions canbe achieved. Under specified lighting conditions it offers an effectivemeans of providing undetected surveillance and high quality one-wayvision to achieve complete privacy.
In order to maintain privacy in the observing area, the ratio ofillumination levels between public and private side, or observed andobserving side, must be 8:1. It is also advisable, if absolute privacyis essential, to have dark furnishings, to wear dark clothing in thearea from which observation is taken place, and to ensure the lightson the observed side are not directed at the glass.
ApplicationsPil king ton Mir ro pa ne™ is the ideal choice for supermarkets,computer rooms, banks or cash offices, where areas need to be keptunder observation or hidden from public scrutiny. It is alsoappropriate for patient monitoring in hospitals or residential careestablishments. Pilkington Mir ro pa ne™ is available in 6 mmannealed form.
Pilkington Mir ro pa ne™ is normally only used for internalapplications. In such cases, since neither side of the mirror will beexposed to the weather, glazing materials such as adhesive cottonbased strips, plastics or rubber channels can be used in a suitableframe. The glass must be installed with the coating on the observer’sside. In such situation glass on the observer’s side appears like anormal mirror and helps to hide the fact that the glass is used forsurveillance purposes. In addition such position of the coating avoidsa risk of finger prints, scratches etc. on the higher traffic side of theglass (e.g. in shops). When used within an insulating glass unit, thecoating should face the cavity, and the Pilkington Mirropane™ glassshould be on the observer’s side.
If you would like to use Pilkington Mirropane™ in externalapplications, please contact your local Pilkington representative.

Pilkington Optiwhite™
Extra clear low iron float glass
DescriptionAn extra clear low iron float glass. The glass is practicallycolourless, and the green cast inherent to ordinary clear float glass,which is particularly noticeable in thicker glasses, is virtuallyeliminated. Pilkington Opti whi te™ offers the highest level of lightand solar energy transmittance.
ApplicationsPil king ton Opti whi te™ is recommended for applications that requirehigh light transmission or for which a glass of neutral colour is desired.These include clear fire protection glazing, laminated security glazing,insulating glass units, photovoltaic modules, solar collectors, projectionroom windows, shop fronts, demonstration counters, shelving,showcases, table tops and other frameless glazing applications.Pilkington Opti whi te™ is also ideal for glass which is to be ceramicallydecorated, as the true colours of the decoration will show through the glass. The colour neutrality of Pilkington Opti whi te™ is mostlynoticeable in applications where the edges of the glass are exposed,for example in shelving or table tops.
Features and benefits● Practically colourless compared to ordinary clear float glass, ideal
for applications where the glass edges are visible or when a neutralcolour is desired.
● Highest light transmittance (1% higher than clear float glass in 3 mmthickness – 6% higher in 15 mm thickness), offering outstandingvisual clarity when unrestricted view is required.
● High solar heat transmittance (4% higher than clear float glass in3 mm thickness), allowing more heat through the glass, thusreducing the need for heating the building.
● Available in annealed or toughened form.● Can be combined with other Pilkington products to offer
additional benefits such as solar control, noise reduction or fireprotection.
● Available in a wide range of thicknesses, from 2 to 19 mm.
