Description
A polyamide window system suitable for all types of buildings. The systems allows for construction of open out casement, and flush/ flush vent types. The 70 mm polyamide window system is designed generally to BS 4873: 2009, British standard for aluminium alloy windows.
Construction consists of outer frame and ventilator frames mitred and mechanically jointed using prepared extruded aluminium corner cleats or die cast mechanical corner cleats and die cast mechanical corner chevrons. Infills are secured by clip fit beads externally or internally. Integral mullions and transoms are secured by driving screws into extruded screw ports. Structural coupling mullions and transoms are available to construct larger composite window units. Weather stripping is by purpose designed bubble seal gaskets. Consult the manufacturer's product manual for limitations on frame and vent size and contact the technical department for details of the maximum spans and loadings applicable to the site conditions.
The system will accommodate a range of glazing thicknesses from 24 mm to 40 mm for double and triple glazed units or infill panels. Glass is dry set between TPE/EPDM bespoke gaskets internally and externally.
