DuPont Tyvek Fluid Applied Air and Water Weather Barrier System

The DuPont Tyvek Fluid Applied System provides a one-coat air and water barrier that can be used alone or combined with DuPont’s commercial wrap. Wall systems are protected from water accumulation, preventing mold, mildew, wood rot, and corrosion.

The low-VOC fluid is ideal for concrete, CMU, gypsum sheathing, and high-rises and can be sprayed on or power-rolled. Its low shrinkage and high elongation and elastic recovery allow it to move with the building. Vapor permeability is 25 perms.
