Grace Construction Products’ Vycor enV-S

This weather-resistant barrier from Grace Construction Products is sheet applied and fully adheres to the substrate and around nails for continuous protection against water leakage and air infiltration. It seals securely at overlaps, eliminating the need for taping the seams. Because it fully adheres on its own, no mechanical fasteners are required. Vycor enV-S comes in roll sizes of 40 inches by 135 feet.
