System Features

EFP SSG

Glass ThicknessThe 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.
DrainageThe system is pressure equalised, drained, achieved by meeting the requirements of “ventilated and drained glazing system” as specified in BS 6262
Thermal Insulation UfClassification 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 IsolationDepending largely upon the glass specification, generally the curtain wall framing reduces the figure by 2dB(A)
MaterialsThe 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 Glass fiber reinforced extrusion.
ConstructionAny instructions regarding the manufacture and installation of the system must be strictly adhered to.
WeatheringGlazing vision strips are made of EPDM conforming to BS 4255 Part 1.
Performance/exposure categoryThe system will achieve the following criteria when manufactured, installed and glazed to EFP recommended procedures.
Air permeabilityBS EN 12207 – Class 4
Water tightnessBS EN 12208 – Class E 750
Wind resistanceBS EN 13116 – 2400 Pa design – 3600 Pa safety
(2400 Pa is dependent upon correct mullion and transom selection to suit span and spacing by project.)
Size limitationsThe size limitation of the system depends mainly on the hardware used. Please advise our office for more details.
