Torch Down Roof Felt SBS Waterproofing Membrane for Flat Concrete Roof
Introduction:
Torch down SBS (styrene-butadiene-styrene) modified bituminous membrane is made by saturating the core felt (polyester felt, glass fiber felt, glass fiber reinforced polyester felt) in SBS modified bitumen, finishing the upper surface with sands, mineral granules or PE film, aluminum film. Sands and mineral granule colors can be customized. For example, blue sand,green sand,grey mineral,etc.
Product features:
1.Traditional building waterproof material, withstand the test of time.
2.High tensile strength, high elongation, strong adaptability to base layer shrinkage deformation and cracking.
3.Good flexibility, even in cold climate zone. No crack of deformation under-20 degree/-25 degree.
4.Puncture resistance, smash resistance, tear resistance.
5. Anti-corrosion, anti-mild.
6.Easy application. Heat the bottom side of the membrane and then stick it on the substrate.
Application:
1) Make sure the roof deck smooth, clean and dry (Moisture <9%), then coat the surface of your roof deck with a kind of bitumen paint till dry to start installation.
2) Two ways in installation:
First, heating and melting method----Heat the PE film of the membrane and roof deck surface by heating and melting method to nearly melted (not flowing), then install the membrane fully bonded to the roof deck with overlaps of 5-10cm.
Second, cold-adhesive method-----Pour the cold adhesive homogeneously on the roof deck, the roll the membrane to install it to be fully stick to roof deck.
3) After installation, a full serious inspection is required to make sure no air bubble, no fold, no falling away to guarantee the waterproof life.
Storage:
1. Packed by plastic bag or adhesive tape.
2. During transportation and storage, keep the package well , put them in a dry airy place, keep away from direct sunlight, acids, alkalis, oil and organic solvents.
