Capsheeting is used for many types of buildings and construction, including sheds and garages, as a top layer in torch-applied roofing. Capsheet is an essential part of installing a torch applied flat roof.
What is Torch applied roofing? Torch-applied roofing is a flat roof covering solution that involves three layers of modified bitumen (felt) melt-welded onto the roof surface and each other with the use of a blowtorch to create an impenetrable, waterproof seal. Torch-on roofing felt is known as one of the quickest and most reliable flat roof installations readily available in the UK. The three layers which are traditionally used in this process are a vapour control sheet, reinforced felt and a cap sheet with mineral finish.
What is a capsheet? A typical flat roof is formed on-site from two or more layers of roofing felt. The top layer is the cap sheet. The cap sheet provides a watertight surface and is an essential part of protecting a building and its occupants. It is required by building regulations for habitable homes to use three layers of felt, so capsheet makes sure that your roof meets all the requirements.
