Specification summary:
Glazing—The system is glazed from the outside, structurally bonded to the moving frame (window vent). Glass should conform the requirements of BS 6262 for thickness and type, in terms of wind resistance, safety and security.
Drainage—The system is pressure equalised, drained, achieved by meeting the requirements of “ventilated and drained glazing system” as specified in BS 6262
Thermal insulation—Classification in accordance with DIN 4108 or EN ISO 10077-1
Thermally broken window: The thermal transmittance ( Uf ) W/m2 K, is depending on the insulator strip, calculated as per EN ISO 10077-1. Comparable with class 1.0 or 2.1 DIN 4108-4 Table 3
Sound insulation—Depending largely upon the glass specification, generally the curtain wall framing reduces the figure by 2db (A)
Materials—The system is constructed from extruded aluminium profiles, using alloy 6063 complying the requirements of BS 1474. The thermal barrier system is achieved by means of PA Glasfiber reinforced extrusion.
Construction—Any instructions regarding the manufacture and installation of the system must be strictly adhered to.
Weathering—Glazing vision strips are made of EPDM conforming to BS 4255 Part 1.
Performance / exposure category— The system will achieve the following criteria when manufactured, installed and glazed to EFP recommended procedures.
