Roofing underlayment fabric

Roofing underlayment fabric

1, Introduction of breathable membrane

1.1 PMAX breathable membranes have excellent performance on water proof, vapor permeability and UV resistant, which are widely used in construction as roof underlayment and wall membrane. They can prevent duct, water drop from our side, but can allow air to pass through.           
1.2 PMAX breathable membranes have three lamination layers:
1st  layer: PP non-woven fabric on top layer for protection and reinforcement;
2ndlayer: Micro-porous PE film in the middle layer as breathable layer;
3rd layer:roofing underlayment fabric on bottom layer for protection and reinforcement;
1.3 PMAX breathable membranes has the following advantages:
t Permits roof & wall to breathe freely  t Excellent mechanical resistance
t Long term 4 months UV resistance   t 100% waterproof function
1.4 Usage on roof and wall
Breathable membrane with one tape   Breathable membrane with two tapes
2.4  roof underlayment
For USA market, non-woven are laminated with PE woven with PE coating are used as roof underlayment and house wrap. They performs very well in function with high tensile strength.

The roof underlayment is as below:

1,Non-slip layer is the upper layer made by non-woven and it can be printing with over lapping lines and logos etc.
2, PE woven layer is made by PE woven, mainly used as tensile strength layer.
3, PE coating layer is used as waterproof layer.

The color of PE woven, grammage, printing can be ordered according to customer's requirement.
