Product Overview

VDST Series Acrylic Double-Sided Sealing Tape is designed for securing and sealing overlapping layers of waterproof and vapor-permeable building membranes. Installed between membrane laps, it creates a hidden bond that helps maintain a clean exterior surface while improving airtightness and water resistance at critical overlap joints.

As part of the Vantell WRB and membrane seam sealing system, VDST helps reduce wind-washing, air leakage, and moisture penetration at membrane lap joints. It is suitable for housewraps, breathable membranes, vapor barriers, and related building envelope sealing details.
