Roofing system specialist Firestone has launched V-Gard; a next generation air & vapour control layer (AVCL) system suitable for use as part of all Firestone warm roof build-ups.
Developed to combine exceptional levels of vapour control with excellent adhesion to both the substrate and the insulation layer, V-Gard is a glass fibre-reinforced aluminium foil membrane with a self-adhesive backing. A film coating on the aluminium face is said to ensure excellent compatibility with PU-adhesives and the new system has been designed for use with Firestone’s ISO Twin-pack PU adhesive.
Carl Bailey, Regional Technical Manager at Firestone explains: “As the thermal performance of the building envelope improves, the risk of condensation affecting the insulation layer increases, unless an AVCL is installed to provide effective and permanent protection from vapour rising from within the building.
“With V-Gard we have enhanced the level of vapour control to create an AVCL that is suitable for buildings susceptible to high humidity, such as swimming pools, while ensuring excellent adhesion to both the substrate and the insulation layer and offering ease and speed of installation with a cold-applied, self-adhesive solution. As part of a high specification Firestone warm roof build-up, V-Gard™ will enhance the thermal performance of the building and extend the service life of the roof.”
Carl added: “Our goal was to create an AVCL which would be easier to install, offer enhanced performance and deliver an extended service life for the whole roof build-up and we believe that V-Gard achieves all of those criteria.”
