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"
