Polyanchor SU is a lightweight, nailable synthetic roof underlayment designed to protect the roof deck in commercial buildings. It offers superior strength compared to traditional felts, resulting in enhanced wind uplift resistance, increased durability in the face of heavy foot traffic, and resilience against adverse weather conditions.
It’s suited for asphalt shingles, synthetic shingles and cedar shake roof covering systems, accommodating a variety of roofing materials. When it’s paired with Polystick IR-Xe self-adhered shingle underlayment installed on eaves and valleys, Polyanchor SU provides a complete solution for ice and water protection to ensure the longevity of the roofing system.
