Built Up Felt Roofing Systems

Daventry Northamptonshire

A Built Up Roof Membrane is made up of two or more layers of bitumen sheet, these sheets are bonded together with hot bitumen or by torch method. This system gives more levels of defence against water ingress.

The majority of materials consist of a reinforced base layer of polyester coated with modified bitumen, this is popular choice of roof system because of the strong adhesive properties of bitumen, it is also the nature of the reinforced base which gives this system the strength and fatigue resistance which makes it so popular. 

Torch On Membranes

A range of APP and SBS membranes which utilise distilled and modified elastomeric polymers combined with thermally bonded and rot proof polyester reinforcement to give excellent mechanical properties such as stability, heat expansion damage, aging and resistance to atmospheric conditions. 

Pour and Roll 

These high performance membranes use modified bitumen reinforced with non woven polyester, this system offers resistance to aging and atmospheric conditions. 

Heat Activated & Self Adhesive

Heat activated membranes are a solution to a roofing situation where direct torching or hot bitumen applied directly to the roof deck is not acceptable. Using distilled bitumen and heat sensitive adhesives, this system is manufactured to adhere using a Peel and Seal technique without the need for hot bitumen or gas torches.
