1.Waterproof roofing underlayment

hybrid Waterproof roofing underlayment is an 8-layer laminated roofing underlayment consists of multiple layer of asphalt, synthetic fiber, non-woven, and HDPE, provides a vital second layer of protection of the building for waterproofing, and to prevent roof damage from rain or snow. Its construction results in high strength, low weight, unmatched tear resistance and long life tendency also almost half the cost of other synthetic underlayments.

Characteristics:

Anti-leaking and tearing: passed 110 mph wind test and 4-hour water spray test with cap and roofing nails.

Excellent tensile:       CD>=300, MD>=300

Wrinkle free:         lay flat,stay flat, but flexible

Anti-skidding:       textured surface provide good walking surface during installation

Excellent stability: strong fiber reinforcement, give the excellent elongation and life tendency

8-layer construction hybrid technology combines asphalt, synthetic fabric, HDPE

Lightweight:         faster and quicker, over 450sq.ft coverage per roll, easy to carry and easy installation

High temperature resistance: up to 260°F

ASTM standard:       meets ASTM D 1970 for nail sealing ability of roofing underlayments

UV endurance:         up to 90 days exposure for roof finishing
