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 Duofix™ Technology, 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.

Typical Applications

• Nailable anchor sheet over approved steep-slope wood decks for temporary
waterproofing protection
• Base sheet for Polystick tile underlayments for concrete, clay, and slate tiles roof
covering systems
• Water-resistant barrier on steep slope roofing under asphalt shingles and shakes

Features and Benefits

• Duofix™ Technology provides superior wind uplift resistance.
• Top surface specially designed to provide highly bondable surface for Polystick
• Surface engineered for walkability on sloped roofs
• High tensile-tear strength mat provides increased fastener and plate tear through resistance
• Nail sealing modified asphalt compound
