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 does not need to be cut into shape. The underlay is made of one seamless piece of material, so that it is 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.
