Product Category:Underlayments

Description:

This 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 on top 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.

Applications:

- to serve as an essential part of the roofing system

- to serve as a temporary roofing cover during construction

- to serve as a safety "net"
