Polyglass: Polyanchor HU and HU PLUS


Polyanchor HU and Polyanchor HU PLUS are mechanically attached modified-bitumen hybrid underlayments for tile roofing. Their Tri-Strata construction combines nonwoven fabric facers with a modified bitumen core comprising more than 80 percent of each product, supporting traction, tear and puncture resistance, deck stability and nail sealability around fasteners. Polyanchor HU is intended for new construction; HU PLUS addresses reroofing, heavier jobsite traffic, deck variability and material staging.
