System 17 Sloped Glazing uses curtain walling profiles. It has been developed for mono or dual pitched roofs with a minimum pitch of 15º from the horizontal, subject to the structural sections being designed to accommodate the applicable loads in accordance with the relevant site conditions and application.


– Thermal:

  • All windows/ screens, in conjunction with a suitable glazing specification, have been designed to meet the current requirements of Building Regulations Approved Document L for England and Wales, Technical Handbook 6 for Scotland and Technical Booklet F for Northern Ireland. Consult with Metal Technology for details.

– Weathertightness:

  • Class III to BS 6375: 1989 Part 1 and BS 5368.

– Dynamic Test: In accordance with the CWCT sequence B test regime using a representative two storey test sample:

  • Static Air Permeability: <1.5 m³/hr at 600 Pa.
  • Static Water Penetration: Zero ml at 600 Pa.
  • Dynamic Water Penetration: Zero ml at 600 Pa.
  • Structural Performance: 2400 Pa (140 mph).
  • Safety Gust Performance: 3600 Pa (210 mph).

– Deflection:

  • All structural profiles can be designed so that maximum deflection of any member shall not exceed L/200 of its span, with no evidence of any permanent deformation once the load has been removed.

Incorporated components:

A range of specialist roof windows can be incorporated. Consult with Metal Technology for recommendations and details.
