GAF FeltBuster is a high-traction, synthetic roofing felt that adds a critical moisture barrier between shingles and the roof deck. Its non-asphaltic polypropylene construction is lightweight, tear-resistant, and resists wrinkling for a smoother shingle installation.
Key Features:
- High-Traction Surface: Special spunbond top layer provides superior foot traction for safer installs.
- Tear-Resistant Durability: Tough synthetic build helps resist damage underfoot and in high winds.
- Moisture Protection: Acts as a secondary water-shedding layer to help prevent wind-driven rain intrusion.
- Wrinkle-Resistant: Non-absorptive material avoids water uptake and unsightly wrinkling that can telegraph through shingles.
- Lightweight 10-Square Roll: 4 ft x 250 ft (1,000 sq ft) roll is easy to carry and handle on the roof.
