FEBRUARY 07 - CONDENSING COLD ROOF SOLUTION



Compliance with new NHBC standards on roofspace ventilation is being simplified with what is being heralded as ‘the ultimate cold roof solution’.

The amendments to BS5250: 2002 introduced in 2005 recommended that BOTH a vapour permeable (LR) roof underlay AND ventilation should be fitted to combat the risk of condensation in cold roofs. The approach is being adopted by the NHBC in its 2007 Standards, requiring ventilation in all pitched roofs regardless of whether they incorporate a vapour permeable underlay. Specifically in regard to vapour permeable underlays used in cold roofs, the NHBC requires 5000mm2/m of high level ventilation to be used.

Glidevale Ltd, one of the UK’s leading suppliers of roof underlays and ventilation systems, has developed a complete package for builders, to achieve compliance: ‘the Ultimate Cold Roof Solution’. The package combines its Protect VP400 vapour permeable underlay and Fulmetal Rediroll universal ventilated dry ridge and hip system, simultaneously providing the vapour permeable underlay and high level ventilation from one source.

Protect VP400 is a high performance vapour permeable (LR) underlay that is entirely watertight, with BRE certification for use in both warm and cold pitched roofs. It is further certified for unrestricted use with regard to wind uplift for all exposure conditions in the UK and Ireland, and does not generate noise under wind loading.. Its three layer laminate construction provides very low resistance to water vapour but at the same time will resist at least 3m head of water when tested to BS EN 20811:1992.  Protect VP400 can be used as a temporary weatherproof covering for up to three months

Glidevale Fulmetal Rediroll is a continuous ventilated aluminium roll with integrated fixing that is simply laid across the ridge to provide ventilation and resistance to driving rain penetration, providing a throughflow of air into the roofspace, avoiding potential damp and condensation issues in the roof void. It design eliminates the need for ridge fillers and unions, and fits all tile profiles and slates, and features integral fixings to enable the system to be secured in place on both ridges and hips without any other fixings or specialist tools.
Protect VP400 and Fulmetal Rediroll are just part of an extensive range of Glidevale roofing and ventilation products developed to be innovative yet competitive, and meet the changing demands of the marketplace.
