POLYANCHOR® SU
Synthetic, Self-Adhered Underlayment
Polyanchor SU is a lightweight, nailable synthetic roof underlayment designed to protect the roof deck. Polyanchor SU is stronger than traditional felts for improved wind resistance, durability through heavy foot traffic and adverse weather conditions. Polyanchor SU’s non-woven fiber surface top surface and polymeric coated bottom surface provides enhanced walkability.
Polyanchor SU is ideally suited for asphalt shingles, synthetic shingles, and cedar shake roof covering systems. Polyanchor SU is preferably matched with Polystick IR-Xe installed on the eaves and valleys for ice and water protection.
