CURTAIN WALLING AND ALUMINIUM SHOPFRONT SYSTEMS

The range of profiles is based around 75mm, 100mm and 125mm mullion and transom designs, plus a 50mm box transom accompanied by purpose designed ancillary items required of a high performance curtain wall system.
The choice of profile sizes and frame design is determined by the expected exposure to local wind pressures.
The system can accommodate 6mm, 6.4mm 8.8mm, 10mm, or 10.8mm single glass units or panels with the use of aluminium adaptors and gasket variations, and 24mm or 28mm double glass units or panels. Vents made using the KAS 269 Curtain Wall Vent Outer Frame (from the 50mm Window Suite) can be fitted in the same way as a 24mm glass unit.
The system is designed for pressure equalised zone drainage, which is achieved with drained and ventilated glazing rebates. Infills are retained with rigid PVC pressure plates incorporating co-extruded weather seals. Inner seals are made from EPDM, and are also available as vulcanised corner components.
The Kestrel system has been independently tested by a UKAS certified body in accordance with the CWCT test method for Curtain Walling.
Curtain wall sections are designed to carry self weight, glass weight, wind pressures and other imposed loads.A curtain wall mullion must NEVER be used as a primary structural member within the building, or have loads designed for the primary structure transferred to the curtain wall grid.
The shopfront system has profiles to suit both flush glazed and bead glazed applications, or a mix of the two. The standard dimensions are 100mm front to back and 45mm wide, with some sections having a width of 50mm or 100mm. The typical wall thickness of this system is 2.5mm. 3D frames can be achieved with the 90 degree and 135 degree corner posts, or with custom pressings for other angles.
The Doors system is suitable for fabricating many types of swing and Sliding Doors, and can be used in conjunction with both the shopfront and Curtain Wall Systems.
The standard dimension is 45mm front to back, with multiple sizes of rails and stiles. The stiles include woolpile carrying versions to provide draught-proof seals. The typical wall thickness of this system is 2.5mm.
The doors are bead glazed, and can accommodate glass units or panels up to 28mm thick by varying the beads used. There are several low threshold sections to choose from. Sections are also available for making louvre Panelled Doors.
Anti-finger trap stiles are available for swing or Pivot Doors, meeting the stricter regulations now in force. Transom closer profiles are used to house and conceal the door closers, and form part of the frame. Rebated infils and thresholds allow for the construction of Hinged Doors. Swing doors can also be automated.
