Safety That Optimizes Performance & Keeps The Noise Down

Stay Calm With

50db Sound Attenuation

Acoustic Glass

Professional planners and architects need to select appropriate glazing

solutions for commercial buildings. With the various factors that have to be

considered in selection, this could be a daunting task, such as meeting the

original design concept, the solar, optical and acoustical performance

requirements.

Glass has been known to be a poor sound attenuatorby property, but with

technological combinations of various glass types and acoustical frames,

sound can effectively be reduced even up to 50dB, intelligently.

Glass As A Sound Barrier

Glass used in building construction provides substantial benefits. To optimize the

acoustical performance of glass for specific applications, the points to be considered are

the mass, stiffness and damping characteristics. The only effective way to increase

performance is to increase the thickness, because stiffness and damping cannot be

changed.

Commercial buildings use a wide variety of glass types, which may enhance solar control

and safety performance. Monolithic glass will provide the lowest acoustical performance

levels. Laminated glass can provide higher acoustical performance levels than

monolithic glass due to the sound damping characteristics of the polyvinyl butyral (PVB)

interlayer used to permanently bond the glass plies together. And, insulating glass tends

to provide the highest STL potential of any glass product due to the versatility of the

product and its ability to combine monolithic and laminated glass plies.

How Sound Penetrates

Sound transmission can occur through various sources other than glass or windows. The

complete building envelope has to be considered as sound may be transmitted through

many components of a building structure and this transmitted sound may be absorbed in

varying degrees by other components of the building. Another condition that can occur in

building construction is sound flanking where sound from one side of an acoustical

barrier can find alternative routes through pipes, HVAC ducts, electrical conduits, outlets,

plumbing, drains and wall vents.

Notes:

Pyrolytic Solar Reflective Glasses can be assembled with coating outside or in contact with the air

cavity (surface #1 or #2). For Low E or Solar Low E whether Pyrolytic or soft coated the coating will

have to be in surface #2 or #3 of the unit to take advantage of the Low E characteristic. For units with

Polycarbonate, the compatibility of sealants with Polycarbonate is to be confirmed. Glass shapes

shall comply with insulating process requirements.

Ideal Applications Of Tone Glass

Airports

High decibel sounds from aircraft take-off and landing can be attenuated in airport

terminals, offering passengers clear views and noise control for a peaceful transitional

experience during their travels.

Hotels

Hotel buildings can make effective use of Tone Glass to match their safety and noise

control requirements between busy traffic circulation areas and high noise level

locations, offering visitors a confortable and serene experience.

Recording Studios

The application of Tone Glass in music and recording studios supports the external

environment more than the internal, in the fact that it prevents the noise levels from

leaking out, so as to cause negligible disturbance to nearby office/residential

locations.

Other Acoustic Applications

As per requirement, Tone Glass can be configured to meet the most urgent

requirements in diminishing noise, like in hospitals - where patient serenity is of

importance, or in the case of custom requirements like glass-walled discotheques, etc.

Color Rendering Index (CRI)

The ability of transmitted daylight through the glazing to portray a variety of colors

compared to those seen under daylight without the glazing. Scale is 1 - 100. For instance,

a low CRI causes colors to appear washed out, while a high CRI causes colors to appear

vibrant and natural. In commercial glass, CRI indicates the effect the specific glass

configuration has on the appearance of objects viewed through the glass. Heat gain is

heat added to a building interior by radiation, convection or conduction.

Heat Transfer Methods

Heat transfer occurs through convection, conduction or radiation (also referred to as

"emission"). Convection results from the movement of air due to temperature differences.

For instance, warm air moves in an upward direction and, conversely, cool air moves in a

downward direction. Conduction results when energy moves from one object to another.

Radiation, or emission, occurs when heat (energy) can move through space to an object

and then is transmitted, reflected or absorbed.

Light to Solar Gain

Ratio of the visible light transmittance to the Solar Heat Gain Coefficient. A higher LSG

ratio means sunlight entering the room is more efficient for daylighting, especially for

summer conditions where more light is desired with less solar gain. This ratio is the

measurement used to determine whether the glazing is "spectrally selective."

Low-E Coatings

Relatively neutral in appearance, low-E coatings reduce heat gain or loss by reflecting

longwave infrared energy (heat) and, therefore decrease the U-Value and improve energy

efficiency. Current sputter-coated low-E coatings are multilayered, complex designs

engineered to provide high visible light transmission, low visible light reflection and

reduce heat transfer.

GlossaryTechnical Data

Solar Heat Gain Coefficient (SHGC)

The percent of solar energy incident on the glass that is transferred indoors, both directly

and indirectly through the glass. The direct gain portion equals the solar energy

transmittance, while the indirect is the fraction of solar incident on the glass that is

absorbed and re-radiatedor convected indoors.

Solar/Reflective Coatings

Typically, highly reflective coatings that reduce solar heat gain through reflection and

absorption. Though very effective at reducing heat gain, visible light transmittance is

generally low and U-Values are not as energy efficient as low-E coatings.

Transmittance Percent

Percentage of incident ultraviolet energy that is directly transmitted through the glass.

Long-termexposure to UV light may result in fabric and pigment fading, plastic

deterioration and changes to the appearance of many types of wood.

Ultraviolet radiant energy from the sun having a wavelength range of 300 to 380 nm with

airmass of 1.5.

U-Value (U-Factor)

A measure of the heat gain or loss through glass due to the difference between indoor &

outdoor air temperatures. It is also referred to as the overall coefficient of heat transfer. A

lower U-Value indicates better insulating properties. The units are Btu/(hr)(ft2)(°F).

Relative Heat Gain (RHG)

The total heat gain through glass for a specific set of conditions. This value considers

indoor/outdoor air temperature differences and the effect of solar radiation.

R-Value

A measure of the resistance of the glazing to heat flow. It is determined by dividing the U-

Value into 1. A higher R-Value indicates better insulating properties of the glazing. R-Value

is not typically used as a measurement for glazing products and is referenced here to

help understand U-Value.

Shading Coefficient (SC)

An alternative measure of the heats gain through glass from solar radiation. Specifically,

the shading coefficient is the ratio between the solar heat gain for a particular type of

glass and that of double strength clear glass. A lower shading coefficient indicates lower

solar heat gain.

Solar Energy

Radiant energy from the sun having a wavelength range of 300 to 4000 nm, which

includes UV (300 to 380 nm), visible light (380 to780 nm) and near infrared energy (780 to

4000 nm).

% Reflectance Out - percentage of incident solar energy directly reflected from the glass

back outdoors.

% Absorptance - percentage of incident solar energy absorbed into the glass.

% Transmittance - percentage of incident solar energy directly transmitted through the

glass.

The sum of percent reflectance out + absorptance out + transmittance = 100%. An

additional consideration is emission, or emissivity. This refers to the reradiation of

absorbed energy that can be emitted toward both the exterior and interior of the building.

Emissivity is controlled through the use of low-emissivity, or low-E coatings.
