EXPERIENCE, ESTIMATING, MANAGEMENT & INSTALLATION EXPERIENCE

More than two decades of experience has proven the team constituting Reflection Windoor Technology more than capable of handling some of the largest and most complex projects throughout the Middle East. Our team’s involvement from conceptual planning through steadfast quality control in every phase of the work has established our experience base. Our future clients can count on us for our technical knowledge and our long-term alliances with preferred vendors which we utilize to complete projects on time and on budget. Our vast experience includes, but is not limited to:

• Complex Curtain Wall • Unitized Curtain Wall and Window Wall • High Performance, Heavy Commercial Window, Sliding Glass Door, and Terrace Door • Structurally Glazed System • Metal Wall Panel System • Louver, Sunshade, and Storm Panel • Glass Handrail • Fire and Blast Resistant Product • Entry System including Balanced, Revolving, and Frameless • Basic Storefront

ESTIMATING

To begin each project, Reflection Windoor Technology' estimating team analyzes design criteria, local building codes, and the project schedule. We utilize an extensive database of competitive and well-qualified vendors worldwide, along with sophisticated estimating software. As a result, our clients get budgets and hard-price quotes that balance cost, performance, and aesthetics.

MANAGEMENT

At Reflection Windoor Technology, our Project Management team goes well beyond the expected. By the end of an installation you can be sure that each component and every aspect of the project has been triple-checked for accuracy––and then checked again. Stringent quality control standards in the field include a series of well-managed redundant check systems that ensure the integrity of your project. Our team's dedication to quality is one reason Reflection Windoor Technology is well known for unparalleled field installations. Our plan of attack begins with project shop drawings, and the product test reports which determine the caulking and fastening details required for each product to reach peak performance. We continue with on-site installation training, building mock-ups, planning installation sequences, and arranging on-site staffing and management. Dry-in and substantial completion are important, but final touches such as punch list work prior to handing the project to the owner, is also a top priority. In addition, constant communication with our

Page 6 of 54

Clients, vendors, and staff are vital to the success of each project, as well as our commitment to first-class service. This means hiring only those who are skilled and knowledgeable in glass installation, and working hard to keep them on our team for years to come. Crew size consists of two to six people, depending on the weight of the product being installed. Each crew member is an experienced craftsman or an apprentice-in-training. Reflection Windoor Technology does not utilize general laborers and/or subcontract labor for the installation of materials. The installation crew reports to the on-site Reflection Windoor Technology Job Captain and, subject to the size of the project, a Foreman will be utilized between the installers and the job captain. A Job Supervisor is an authorized representative of Reflection Windoor Technology who performs on-site management, maintains quality control, and attends job-site meetings. Job Captains report to Reflection Windoor Technology Project Management team who, in turn, report to our Production Manager and Vice President of Production.

INSTALLATION

Installation begins with shop drawing detail(s), product test report(s), on-site training, and mock-up(s). The accurate creation and implementation of shop drawing detail(s) are imperative to a successful project installation. In correlation with the project’s water consultant(s), Reflection Windoor Technology works with surrounding trades to supply and install products that are properly weather sealed. Product test reports dictate the proper caulking and fastening methods in which to utilize in order to gain the maximum performance from each product. Regardless of the redundancy of the work performed by Reflection Windoor Technology employees, all installations begin with on-site training. Training includes Reflection Windoor Technology' management and installation teams, the manufacturer’s representative, shop drawings, and product installation manuals. Besides the manufacturer’s installation recommendations, Reflection Windoor Technology implements its own stringent installation details which include methods from handling the product carefully to avoid damages and/or scratches to “buttering-up” each and every last installation fastener with caulk. Reflection Windoor Technology recommends that mock-ups are built and tested prior to the project installation in order that all installation methods can be confirmed at the start of the project. Each installer is responsible for preparing and executing a written-check report for each product they install. The Foreman and/or Job Captain then verify the work and sign off accordingly. The Project Manager ultimately reviews all written reports and files a report weekly at Reflection Windoor Technology’ Dubai Office. At Reflection Windoor Technology, we are not afraid to admit and prove that our capabilities far exceed that of most other firms within our industry.

WINDOWS & SKYLIGHTS A window is an opening in an otherwise solid and opaque surface that allows the passage of light and, if not closed or sealed, air and sound. Windows are usually glazed or covered in some other transparent or translucent material. Windows are held in place by frames, which prevent them from collapsing in. We can produce the following types.

TYPES

- Double-hung sash window - Roof lantern or copola - Single-hung sash window - Bay window - Horizontal sliding sash window - Oriel window - Casement window - Thermal window - Tilt and slide - Fixed window - Tilt and turn - Picture window - Transom window - Multi-lit window / divided-lit window - Jalousie window - Emergency exit window / egress window - Clerestory window - Stained glass window - Skylight - French window - Roof window - Awning window

SKYLIGHT

Skylight windows provide the building with a unique lighting function during the day. Skylights are a built in roof window and come in many different shapes and size and even surfaces. There are flat sky windows and bubble skylights that have more of a dome shape and protrude out from your roof. Both are available in square and rectangular shapes. For fresh air, then there are ventilating sky windows rather than the usual skylights that stay shut.

DOOR SYSTEMS

A door is a panel or barrier, usually hinged or sliding, that is used to cover an opening in a wall or partition going into a building or space. A door can be opened to give access and closed more or less securely. The term door is also applied to the opening itself, more properly known as the doorway. Glass and UPVC doors are mounted on a pre-built frame to match the size of the door space. Flush doors are those with a completely flat surface. They are un-paneled and have no trim around the edge. Our doors are supplied to us manufactured from an aluminum frame which is concealed by sheets of composite or aluminum. A surface veneer may also be added if the door is to retain a more natural wood-look. Flush doors are most often used internally, when their hollow-core will be filled with corrugated cardboard. Heavier external flush doors will include a central horizontal rail to allow a letter box to be included, and the remainder of the core may be filled with hardwood blocks, particleboard or fiberboard. The frame of a fire-resistant flush door is filled with solid fire-retardant material.

Paneled Doors Paneled doors are put together using a frame of vertical stiles and horizontal rails of soft or hardwood, that are connected by mortise and tendon joints (using wedges), or dowel joints in cheaper versions. This aluminum framework then supports wooden panels which can be flat, beveled or fielded, or louvered slats or glass. A paneled door can include anything from a single large panel, to in excess of 24 small panels, so these doors are available in a wide variety of styles. This construction tends to minimize any swelling, warping or shrinking that the wood may undergo with variations in humidity.

CURTAIN WALLING SYSTEM

Is a term used to describe a building facade which does not carry any dead load from the building other than its own dead load. These loads are transferred to the main building structure through connections at floors or columns of the building. A curtain wall is designed to resist air and water infiltration, wind forces acting on the building, seismic forces (usually only those imposed by the inertia of the curtain wall), and its own dead load forces.

Curtain walls were originally used to protect medieval castles and were built of stone. Modern curtain walls are typically designed with extruded aluminum members, although the first curtain walls were made of steel. The aluminum frame is typically in filled with glass, which provides an architecturally pleasing building, as well as benefits such as day lighting. However, parameters related to solar gain control, such as thermal comfort and visual comfort are more difficult to control when using highly- glazed curtain walls. Other common infill’s including: stone veneer, metal panels, louvers, and operable windows or vents.

Curtain walls differ from storefront systems in that they are designed to span multiple floors, and take into consideration design requirements such as: thermal expansion and contraction; building sway and movement; water diversion; and thermal efficiency for cost-effective heating, cooling, and lighting in the building.

Design Principles for Exterior Walls

We follow the principles where a building enclosure may be broadly defined as a set of interconnecting elements which separate the outside from the inside. These elements would include exterior walls, a roof, other components such as windows and doors, and sometimes exposed floors. The function of a building enclosure is to control the penetration of snow, wind, rain and sun to the inside and to contain the desired indoor climate. The enclosure must meet many individual requirements but for the purpose of this paper they are limited to the following six:

Page 23 of 54

1. Control of air flow, control of heat flow, control over the entry of rain and snow, Control of sunlight and other forms of radiant energy, control of water vapor diffusion,

2. Accommodation of building movements. Thermal Insulation (Control of heat flow)

The control of heat flow is generally achieved through the use of insulation. Although it is not apparent from the exterior, the curtain wall system uses considerable insulation usually behind spandrel glass or any opaque panels. Because of the materials used in the structure, i.e., glass and metal, which are highly conductive, the system must also contend with potential condensation on the interior surfaces.

The "Rain Screen" Principle (Control of rain and snow penetration)

To control rain penetration through exterior walls the conventional approach is to seal the exterior façade of the building. However, experience has shown that it is unreasonable to expect perfect sealing of a façade; most sealing strategies require continuous attention and maintenance.

Solar Radiation (Control of sunlight and other forms of radiant energy)

Solar radiation falling on building surfaces may have two distinct effects: the first is to cause a significant change in temperature of the façade elements and the second is the slow but destructive effect of ultraviolet radiation impinging on all materials, particularly organic. On curtain wall systems the most important concerns with solar radiation have been the thermal expansion and contraction of curtain wall components, in particular those forming the outside cladding, and the effects of solar radiation on the glazing elements. A warping of glass occurs due to differences in temperature between the inner and outer panes, while pumping results from expansion and contraction of the air in the cavity of the sealed units. Daily and seasonal temperature differences can also cause this effect. The action of the window (thermal pumping) is particularly stressing to the inner air seal; however, serrated edges or recessed flanges keep the seals from pumping out. Most of the ultraviolet-sensitive materials in curtain wall systems are located in the pocket and cavity areas of the joints and are partly shaded by metallic and glass components.

The Vapor Barrier (Control of water vapor diffusion)

Water in its gaseous phase (water vapor or humidity) always tries to migrate from a region of high water vapor pressure to a region of lower pressure. The migration of water vapor through a wall can be compared to heat flow; it moves through all materials at a rate that is dependent on both the resistance of the materials to water vapor flow and the difference in water vapor pressure on both sides of the material. The migration of water vapour through an assembly of materials is not a serious problem in itself, provided it does not condense to liquid form in the material or wall. If water vapour is likely to condense in a wall, the principal defense is to restrain its migration by using, a "vapour barrier" with a high water vapour flow resistance, positioned on the warm side of the insulation material or wall assembly.

Page 24 of 54

Joints and Tolerances (Accommodation of building movements)

Movements of the structural elements of a building must be determined prior to the design of an exterior wall system. Movements may be grouped into three types:

1. live load deflections due to occupancy loads or peak wind loads on the building façade, and dead load deflections of the building structure,

2. expansion and contraction of materials as a result of temperature, radiation and sometimes hygroscopic loading,

3. Slow but inexorable movements due to gradual deformation, such as creep in concrete, foundation settlement, etc.

Designing the Interface 'By Others'

Assuming that most curtain wall systems can perform well or that the components are available to build a quality wall system, we turn our attention to the connections or the interface joint between the curtain wall system and the other parts of the building.

The Parapet

When a curtain wall system is designed to extend upwards past the roof line and thus to get cold, several potential problems must be considered. Without proper termination at the head of the curtain wall system, condensation and frost may form in the tubes and eventually drain to the inside of the building, or icing may force parts of the parapet cap off the building. Also, if allowed to fluctuate with the outdoor temperature, the structural part of the curtain wall system may expand and contract beyond its design limitations, thus straining all connections in and around the parapet elements. The material used to construct the parapet air barrier is of particular importance. While this air seal may be a flexible membrane, it must be able to carry air pressure loads as high as the combined wind load, stack effect, and ventilation pressure or it will rupture and cause a major air ex-filtration problem. It is better to use a rigid material such as sheet metal with appropriate connection details because the insulation on its outboard face must remain in place.

The Corner Interface

Buildings using curtain wall systems are often required to form an inside or outside corner. When two sections of curtain wall meet, the interface detail must be designed to provide control over all of the aforementioned requirements. Because corner details vary considerably from project to project, suppliers do not have stock sections to draw upon to construct this interface detail. However, curtain wall suppliers will fabricate the necessary interface components provided that their participation is solicited early enough in the planning phase, preferably before tenders are closed.

When dealing with an inside corner, the same requirements apply (Figure 5). However, if the mullion caps are in near contact or overlap slightly, it is not necessary to add a further "Rain Screen" baffle over the insulation. The air barrier should be rigid and sealed against the shoulder flanges of the vertical mullions and held in place by suitable pressure blocks. The final architectural solution may require a decorative finish inside to follow the dotted line profile. This

Page 25 of 54

Space should not be insulated; otherwise the structural air barrier becomes a vapor barrier on the wrong side of the insulation, inviting condensation problems.

The Grade Connection

Whether on a concrete curb, a block wall or a concrete floor slab edge, the grade connection interface between the curtain wall and the remainder of the building is particularly sensitive to rain penetration and air infiltration. The most common interface detail is shown in Figure 6. This design approach often results in two performance problems: first, cold air infiltrates through the ends of the vertical tubes, increasing the potential for condensation on the tube surfaces and for glass breakage, and second, rainwater accumulates in the cavity between the curtain wall section and the floor, which will prematurely deteriorate the floor-to-mullion air seal. In keeping with the design requirements for continuity of the air barrier, it must be started from the horizontal mullion lower shoulder flange and extended directly to the floor or curb as in Figure 7. A sealant might be used to create a sloped edge or a water dam, and a small amount of insulation will control any condensation forming on the warm side of the air barrier surface. Then a flashing component should be installed over a pressure block and under the snap cap. This will ensure that surface water draining from the panel above is directed to the outside of the cavity instead of into it.

The Masonry Interface

In the recent past there has been a trend in architectural practice to devise new ways of obtaining the flush façade. Specifically, window glass is often aligned or nearly aligned with the exterior veneer or cladding to create a smooth unsculptured exterior wall. Several general design weaknesses have been found in this type of interface joint, between the masonry and the curtain wall systems. Most often the detail shown in Figure 8 results in condensation on the inside mullion surface and efflorescence on the outside surface of the brick veneer. The reasons are twofold: first, the wall insulation is out of line with the thermal break of the curtain wall mullion. This results in a discontinuity of the insulation plane and creates a thermal bridge that allows part of the interior structural or metallic components to become cooler than the inside dew point temperature. Condensation often shows up on the inside surfaces of the sill mullions. The second reason is a discontinuity of the air barrier, because there was no provision for an air barrier element in the masonry wall; if there is an air barrier, it may be attached to the wrong part of the curtain wall mullion. When this represents a sill detail, the sill flashing connected to the curtain wall mullion must reach over the brickwork and have the appropriate drip profile. This flashing should not be connected on the inner shoulder flange surface of the curtain wall section as it will cause a thermal bridge to occur at the air barrier connection. Similarly the flashing should not go over the cap or be fastened to the cap surface, as more water than necessary will penetrate the cavity between the curtain wall and the masonry. The sill flashing will perform best if it is installed over the pressure block, held in place by the pressure plate and cap. There are also other types of extrusion to suit this application.

Page 26 of 54

The Precast Panel Interface

At times a curtain wall is used in a building façade system with conventional precast panels. Vertical strips of precast panels are interspaced with vertical strips of windows or horizontal strips of precast panels can be interspaced with horizontal strips of windows to create a layered effect of glazing, precast, and glazing. In these combination systems several questions should arise during the design phase: first, will the curtain wall system be connected to a pressure-equalized wall or a precast panel wall using the face seal approach and second, does the sequence of construction allow for the successful assembly of the interface joint? In these cases it is imperative that the general contractor work closely with the designer to arrive at interface detail which is buildable within the sequence of construction and that this detail embody all the elements required of exterior wall design.

The Soffit

This part of the building is perhaps one of the most troublesome and misunderstood parts of the building enclosure. First, it must be determined whether a soffit is to be heated or unheated, as most design decisions must be based on one or the other of these premises. In the event that the soffit is to be heated, then the enclosure area of the soffit, which includes the lower part of the wall façade and the underside surface of the soffit, must be designed to meet all the requirements of an exterior wall. In the event that a soffit is to be unheated, most of the building envelope design requirements must be achieved at the roof/floor element. In this case, it would be wise to consider a complete discontinuity of the structural components of the curtain wall system composing the façade so that no vertical tubes in the soffit area are connected to the corresponding vertical element starting at the floor above and going up the façade of the building. An alternate approach is to construct a narrow vertical enclosure around the curtain wall system facing the soffit cavity so that the curtain wall system is maintained in a warm environment at all times and is properly sealed and insulated.

Sloped Walls (Glass Roofs)

Architects and owners want to see through their roofs. Skylights, atrium and mall spaces are to be bright, open and clear and at the same time provide all the functions of a normal roof. The first attempt at constructing sloping glass walls using conventional mullion sections revealed the major weakness almost immediately. Because of the angle at which the mullions rested, the cavity could not drain and the window unit glazing seal could be continually immersed in water. This caused two problems: it destroyed the inner air seal, which eventually allowed rain to penetrate, and the glazed sealed window unit failed prematurely because the edges were frequently immersed in water. In addition, it was discovered that if sloped walls were constructed in humid environments, severe condensation would form on the glass surfaces, accumulate at the lower edge, and drip from the horizontal bars. While this was not a serious problem, some measure would have to be taken to control the effects of condensation.

Page 27 of 54

The interface connection between a sloping glass wall and other building elements is somewhat complex. However, if the sloping wall abuts a vertical wall that rises above the glass roof, the air seal requirement is the same as that for all of the interface details. An air barrier element must be joined from the flange surface of the horizontal mullion to the similar function element of the adjoining wall. The air barrier must be insulated from the outside and a protective cover installed over the insulation. This cover must also serve another purpose. Because of the possibilities of snow accumulation, the cladding cover should extend sufficiently high up the vertical wall to guard against a water dam buildup at the upper edge of the glass roof and over the cladding joints. This cladding should be one piece where possible and may connect to the normal mullion cap; however, it is probably better to extend it over the cap of the sloping glass curtain wall mullion and fasten it to the mullion face cap. Where a sloping glass wall is required to interface with a vertical glass wall from underneath, consideration must be given to melting snow and ice formation at the edge, and to the condition and continuity of drainage from the sloping roof mullion drain gutters to the wall mullion sections below.
