About product
G.A.P. ASTM 30 D226 Asphalt Saturated Roof Underlayment is a professional-grade asphalt-saturated felt underlayment engineered to provide superior protection beneath asphalt shingles. Each 36 in × 72 ft roll covers 216 sq ft and is designed with a high-strength, nonwoven surface that resists tears during installation. This construction is designed to lay flat and provides a slip-resistant walking surface to enhance safety and ease of use during installation.
Because the underlayment is made from durable asphalt-saturated felt, it does not absorb water or wrinkle like traditional felt. The material resists mold growth, ensuring a dry and stable roof deck. ASTM 30 D226 is up to 4 times stronger than traditional #15 felt, offering excellent wind resistance and durability even during heavy roof traffic and harsh weather conditions.
ASTM 30 D226 is lightweight, with a nominal weight of 26.0 lbs per 100 sq ft, and can be easily handled by roofing crews. Its advanced backside non-slip coating and UV resistance for up to 30 days of UV exposure allow for faster, wrinkle-free installation and longer-lasting protection for the roof deck until the primary roofing material is applied.
ASTM 30 D226 is engineered for easy handling and quick installation. The high-quality, lightweight material features a non-slip surface for added safety on the job site, allowing roofing professionals to work faster and with fewer complications. The rolls are designed to lay flat, improving the ease of installation and minimizing wrinkles. ASTM 30 D226 can be cold-nailed or stapled and is compatible with asphalt shingles, making it a versatile choice for both residential and commercial applications.
ASTM 30 D226 passes ASTM standards and is resistant to harsh environmental conditions, including extreme heat, heavy rain, and high winds. Its strength and flexibility make it suitable for use in a variety of climates, including cold temperatures where traditional felt may become stiff and difficult to handle.
ASTM 30 D226 is a trusted choice among roofing professionals, meeting key industry standards such as ASTM D226, ensuring reliability and superior protection under asphalt shingles.
