  • Designed and manufactured to comply with BS 4873.
  • Window vent frame members are 87 mm front to back and mitre cut at 45°. All corner joints are assembled with screwed corner cleats, thermal corner supports and rebate supports and glued. All joints are glued sealed during fabrication against water entry. Consult manufacturer for further details.
  • Profiles are insulated with polyamide strips, 25% glass fibre reinforced to BUtgb approval, separating the internal and external faces, mechanically jointed and glued to form a single compound profile with a minimum shearing force of 30 N/mm (statistic average).
  • Dry glazed to accommodate a wide range of single, double and triple glazing units with internal clip-in aluminium glazing beads.
  • Extruded synthetic rubber ethlylene propylene diene monomer (EPDM) weather-stripping gaskets to DIN 7863 and ISO 3934, set in undercut grooves in the frame and vent.
