GAF FeltBuster Roof deck protection 48.0-in x 250-ft 1000-sq ft Synthetic Roof Underlayment

Enhanced Walkability — special spunbound surface helps provide increased traction versus typical asphalt felts

Tough synthetic construction — resists tearing and will not absorb moisture, become brittle, or leach oils

Cooler to work on — medium-gray surface is up to 30 degrees cooler than typical black asphalt felts (based on GAF testing with underlayments installed on plywood deck at 90°F (32.2°C) ambient temperature and left exposed to direct sunlight)

Easy to work with super lightweight, 10-square, 48 in (1.23 m) wide roll (versus typical 36 in[914 mm] wide felt rolls)

Durable Non-asphaltic polypropylene construction for long-lasting performance (unlike conventional felts that can disintegrate over time).

A better-looking roof — lies flatter than typical felts and avoids telegraphing of wrinkles, which can detract from the look of the new roof
