VSST Series - Acrylic Single-Sided Sealing Tape

VSST is a versatile single-sided acrylic sealing tape for surface seam sealing, joining and local repairs in building envelope assemblies, including compatible air-control and vapor-control membranes, wall wraps and roof underlays.

Product Overview

VSST Series is a versatile single-sided acrylic tape for surface sealing, seaming and local repairs in building envelope assemblies. Applied over seams and overlaps, it helps maintain continuity at joints in compatible air-control layers, vapor-control membranes, wall wraps and roof underlays.

Its high-performance acrylic adhesive supports bonding to a range of building substrates. Selected panel joints and membrane-to-component transitions may also be sealed after application-specific verification. The tape is hand-tearable and supplied without a release liner for convenient installation.
