The Solstro roofing underlay reduces installation time. It consists of a tear-proof polystyrene film, that is nonwoven and is coated with a vapour layer. Installation is much quicker because it doesn’t need to be cut in to shape. The underlay is made of one seamless piece of material, so that it’s 100% watertight.
The point where the roof and the roof window meet are a critical area for the entire structure of a home and our extra installation set can assist in achieving the best quality of install. Designed to protect the roof and ceiling construction.
