Description

System 17 Roof/ Sloped Curtain Walling has been developed for mono or dual pitched roofs with a minimum pitch of 15° from the horizontal, subject to the structural sections being designed to accommodate the applicable loads in accordance with the relevant site conditions and application.

Performance:

– 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 where applicable. Consult with Metal Technology for details.

– Weathertightness:

  • Class III to BS 6375-1: 1989 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.

Secured by Design:

  • All glazed curtain walling screens, windows, and doors within the ground floor and vulnerable areas shall embrace secure by design.

Standard product features

Type:

Stick system, pressure equalized and drained. The system is thermally broken throughout by means of a continuous thermal isolator located between the external pressure plates and internal framing members.

Glazing system:

Dry glazed using proprietary, high performance captive gaskets. All gaskets are bonded and sealed during construction, using waterproof adhesive. All internal gaskets have pre-moulded vulcanized corners.

Roof glazing purlins use a low profiled bevelled pressure plate only. In addition to the proprietary gaskets:

  • A fillet of neutral cure silicone is run along the exposed upper edge of the pressure plates to ensure surface water can flow easily.
  • A butyl tape is deployed across the joint between the double glazed units below the pressure plate and gaskets.
