Waterproof Membrane Type bitumen sheet waterproof roll materialsTorched SBS modified bitumen waterproof membrane it is SBS (Styrene-Butadiene-Styrene) modified bitumen, torch-on elastomeric waterproof membranes with fiberglass or non-woven spunbond polyester felt ;both sides are coated with polyethylene film or one side coated with polyethylene film, the other side is coated with silica sand, aluminum foil or natural or colored slate chippings (mineral stones).
surface coating materials:PE film\aluminum foil\minerals\sands
Soluble content g/m2
no slippering,no flowing ,no dripping
Fracture elongation, %≥
Phytotrons accelerating ageing
Tension keeping %≥
no slipping, no flowing ,no dripping
3.Features and advantages:
1. High impermeability, high tensile strength, high extension coefficient
2. Puncture resistance, tear resistance, anti-corrosion, mildew resistance
3. SBS is suitable for lower temperature area, while APP is suitable for higher temperature area
4. Perfect durability, service life can up to 30 years
5. Flexible install method: Either by heating and melting method, or cold-adhesive method. Either single or multiple layer.
6. No flow, no dripping in higher temperature;
No crack in lower temperature
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.
Package, transportation and 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.
3. The shelf life is 12 months under normal storage and transportation conditions. After that period, the product can still be used if it complies with all the items in the specification.
