Product Description

3mm SBS / APP Modified Bitumen Roof Shingle Underlayment Waterproof Membrane


Product Discription

It has such advantages as no flow under high temperature condition,being soft under low temperature condition,being high flexible and aging resistant.

Thus the flex durability,flexibility and cohesive force of the asphalt is largely improved.

Therefore,the waterproof quality of the buildings improves a lot and service time also prolongs



1. Type:Type Ⅰ,Type

2. Base felt:PY/G

3. Upper surface material:PE/Sand/Mineral

4. Thickness:3mm-5mm or according to customers requirement


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
