Polyglass Polystick TU Plus Self-Adhered Reinforced Waterproof Tile Underlayment 39 in x 65 ft, 215 sq ft

Polyglass Polystick TU Plus Self-Adhered Reinforced Tile Underlayment is a professional-grade, self-adhered underlayment designed to provide superior waterproofing and protection beneath tile roofing systems. Each 39 in × 65 ft roll covers 215 sq ft and is designed with dual reinforcement, combining a fiberglass mat and a polyester surface fabric that enhances puncture resistance and slip resistance. This construction is engineered to create a robust membrane that is perfect for heavy tile applications and ensures a secure, watertight bond even under extreme weather conditions.

Because the underlayment is made from durable rubberized asphalt, it does not absorb water or wrinkle like traditional felt. The material resists mold growth, ensuring a dry and stable roof deck. Polystick TU Plus is significantly stronger than traditional #15 felt, offering excellent wind resistance, durability, and long-lasting performance even during heavy roof traffic and harsh weather conditions.

Polystick TU Plus is lightweight, with a nominal weight of 79 lbs per roll, and can be easily handled by roofing crews. Its advanced self-adhered adhesive and UV resistance of up to 360 days of exposure provide fast, wrinkle-free installation and long-lasting protection for the roof deck until the primary roofing material is applied.
