  • Outstanding air-tightness and weathering performance independently certified.
  • Superior overlapping drainage channels and thermally broken head and eaves aluminium transoms for enhanced thermal efficiency. 
  • Suitable for double or triple insulating glass units.
  • Tested to CWCT TN66-67 and classified Class 2 Non-Fragile. May be deemed to comply with CWCT TN92 when used with recommended glass specifications.
  • Opening ventilation available for natural or smoke.
  • Designed to conform with the requirements of BS5516 2004 Parts 1 & 2 for the design & installation of sloping and vertical patent glazing when installed within the manufacturers recommendations.
  • Variable pitch down to minimum 5 degrees.
  • Wide centres and long spans means less metal and more daylight.
  • Materials are supplied Mill Finish as standard or may be polyester powder coated to standard RAL or BS colours to BS6496.


ThermGard ALM100


  • A neat 40mm wide box bar design, ThermGard provides a cost-effective alternative to more expensive sloped curtain walling systems without sacrificing aesthetics. Various slim-line box rafters are available to suit small or large spans. Alternatively the carrier rail may be mounted on top of continuous timber rafters – see our ThermGard-R glazing bars. A continuous screw on pressure plate with gaskets provides outstanding glass retention and a choice of decorative external covers are available to provide either contemporary glass roof appearance or a more traditional heritage style for roof lanterns on period buildings.
