As winter continues to bite, roofers, specifiers and builders battling to select an insulating roofing underlay which can cope with winter storms and cold weather may be interested in a new brochure produced by insulation specialist Actis
The document offers technical advice on its insulating breather membrane product, Boost R Hybrid Roof, which is aimed at both the new build and refurb market.
The flexible and easy-to-use product offers an extremely effective way of eliminating condensation and preventing moisture entering the building.
It doesn’t require any special cutting tools, eye or respiratory protection and there’s hardly any wastage
Used on the cold side of roofs, it is quick and easy to install, has a water vapour permeable roofing underlay which acts as a wind barrier suitable for all wind zones (1-5) throughout the UK and a self-adhesive lap to ensure joints between adjacent sheets can be sealed quickly and easily, creating an airtight layer.
In common with sister product Boost R Hybrid, it has the highest thermal resistance of any insulating breather membrane of the same thickness on the market and is extremely cost competitive.
The brochure provides example build-ups in a timber pitched roof using Boost R Hybrid Roof alone, as well as in combination with accompanying Actis products, honeycomb structured insulation Hybris and insulating vapour control layer H Control Hybrid.
The modelled examples specify U-values achievable in each scenario.
