Built Up Felt Roofing Systems
Knowle & Solihull West Midlands
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.
