What is Bitumen felt?
Bitumen felt is a type of building material that is used for water proofing and damp proofing and also Bituminous felt roofing us a waterproofing membrane consisting a thin fiber mat of polyester or glass fibers saturated with bitumen to use in roofing.
This involves installing multi-layered felt fiber mats that are coated on each side with a bituminous coat, for highly effective weatherproofing and a lengthy life span. It is made from bitumen, a sticky, black, semi-solid form of petroleum, and hessian fibers, which are made from jute or other natural fibres.
It is typically used to protect roofs, walls, and other structures from water damage by providing a barrier that prevents water from penetrating the surface.
It is also used to prevent dampness and condensation from forming inside buildings by allowing moisture to escape from the structure. Bitumen felt is typically applied in thin layers using a hot asphalt or tar application process, which helps it bond to the surface and form a watertight seal.
How long does bitumen felt last?
The lifespan of roof felt varies widely depending on the grade and quality of flat roof felt used, and can be anything between 2 years and 20 years.
Is this felt waterproof?
Bitumen (asphalt or coal-tar pitch) is a material made up of organic liquids that are highly sticky, viscous, and waterproof.
Systems incorporating bituminous-based substrates are sometimes used to construct roofs, in the form of “roofing felt” or “roll roofing” products.
