500g Sand Felt Roofing Asphalt Shingles Underlayment Breathable Membrane
500g sand felt roofing asphalt shingles underlayment breathable membrane YAP 500 is based on PET non-woven fabrics and then saturated with modified bitumen,upper surface coated with high strength polypropylene fiber and back side coated with antiskid sand. When applying, it has the advantage of waterproofing, damp proofing,sound proofing and breathable performance.
The YAP 500 is an approved underlay construction of a polyester body which is impregnated and coated with SBS-modified asphalt. . The YAP 500 is a quick mount surface cover as it is easy to handle. Approved down to 6 ° roof slope with concealed mounting.
The YAP 500 is approved under both concrete pans and clay tiles, roofing sheet, striped sheet and surface board. The product has a self-adhesive edge with bitumen adhesive and an opposing edge that is exposed which gives a dense and leakproof joints. The YAP 500 is nailed or stapled and it mechanical attachment must be covered by overlapping wet with the adhesive strip.
1. excellent tensile strength and elongation
2.big surface friction, closely integrated with the grassroots.
3.no smell,no taste, accord with environmental protection requirement.
4.the surface has an function of antiskid to make sure the safety of application.
