PolyAnchor® HV

Jun 06, 2023

PolyAnchor HV is a nailable anchor sheet specially designed for the temporary protection of steep-slope roofs in areas prone to high winds. Designed with ANCHORTIGHT TechnologyTM, PolyAnchor HV uses a strong bituminous bonding surface combined with a special tear resistant fiberglass mat to provide superior wind uplift resistance.

The top surface of PolyAnchor HV is formulated to provide an ideal bonding surface for Polystick polymer modified self-adhered underlayments. The bituminous compounds in the sheet enhances sealability around fasteners and moisture protection while the heavy-duty mat provides strength and tear resistance around fasteners and plates.

PolyAnchor HV is ideally suited for use with clay/concrete tile roof covering systems with Polystick TU Plus or TU Max as the final substrate for the roof covering. PolyAnchor HV is also suitable for use under asphalt shingles.

“Polyglass is excited to announce the launch of PolyAnchor HV. With stricter building codes being enforced in Florida, it has become a challenge to use traditional felts due to poor performance in wind uplift. PolyAnchor HV provides over 80% stronger top surface bond with our self-adhered Polystick Underlayments and 2.5 times greater nail pull through compared to traditional felts.” states Marco Sieber – North America Product Manager – Roofing Membranes
