Things to consider when fitting UPVC fascias and soffits

Hazlemere Windows Roofline System is suitable for use externally to provide a protective and decorative trim at the roofline, where timber or other conventional materials would normally be used. The system will provide protection to the interior of the building from the penetration of moisture. Replacement, rather than over fixing, of existing fascia is strongly recommended. Timber roof structures, to which the system is fixed, must be designed and/or constructed in accordance with the relevant Building Regulations and, as appropriate, in compliance with one of the following technical specifications:

• BS 5268-2 : 2002
• BS 5268-3 : 2006
• The Building Regulations 2000 (as amended) (England and Wales), Approved Document A1/2, section 2A

Hazlemere’s Roofline System comprises a range of cellular UPVC fascia boards, soffit boards, cladding and matching components available in standard white and blue white on request. Plastic guttering and downpipes are also available to match. All these Roofline products are virtually maintenance free, only require cleaning with warm soapy water and a soft damp cloth every couple of years or so.

The cellular boards comprise a closed-cell cellular UPVC core beneath an outer weathering, impact-modified, UPVC skin. The soffit ventilator and other extruded trims are composed of impact-modified UPVC and the injection mouldings of PVC-U. Clear polyethylene film is applied to the outer face of the material before the board is cut to length.

The cellular UPVC components have a similar coefficient of thermal expansion to that of conventional solid PVC-U. A 5 mm gap should be provided at the end of each board (i.e. 10 mm at the joint trim between boards), to allow for movement. Care should be taken not to install the system in extremes of temperature. The recommended temperature for installation is between 5°C and 25°C.

The major advantages of fitting UPVC Cladding, Fascias and Soffits or Guttering, include no more painting, no rotting or warping and much improved insulation. In other words its a bit of a no brainer!
