VaproShield® membranes are breathable, water-shedding, weather resistant barriers that provide high performance vapor control. VaproShield® membranes are your offense for water vapor and your second line of defense for exterior moisture intrusion. Our membranes allow your building to breathe with a vapor permeable fabric that helps to prevent mildew, mold and rot.

VaproShield® products can work in conjunction with most building products and systems. Project scale ranges from single family residential to high-rise towers.

VaproShield® membranes are manufactured using high density polypropylene fabric. Two highly durable outer layers are welded to a finer inner layer that controls the level of vapor transmission.

VaproShield® vapor control products are the result of five years of scientific research & testing. Take vapor control to an all new level with scientifically tested and approved products, proven in construction application since 1997: RoofShield™, WallShield® and WrapShield®.
