VSST Series Acrylic Single-Sided Sealing Tape is designed for sealing seams, overlaps, and joints of various building membranes, including housewraps, breathable membranes, WRB layers, and vapor barriers.

Product Overview

VSST Series Acrylic Single-Sided Sealing Tape is designed for sealing seams, overlaps, and joints of various building membranes, including housewraps, breathable membranes, WRB layers, and vapor barriers. It helps create a continuous airtight and water-resistant connection across membrane joints.

With strong acrylic adhesion to common building substrates, VSST supports long-lasting seam sealing performance in building envelope applications. It helps reduce air leakage, wind-washing, and moisture intrusion at membrane overlaps and critical joint details.
