DuPont Weatherization Residential Sealant is scientifically formulated to bond with DuPont(TM) Tyvek(R) Weatherization Systems, helping create a breathable, protective barrier to increase energy-efficiency; reduce heating and cooling costs; and help protect against water infiltration that could lead to formation of damaging mold and mildew in wall structures.

Up to 40 percent of a home's energy loss is due to air infiltration such as exterior air penetrating cracks and crevices. In fact, an 8 MPH wind moving through the walls of a home is like leaving a window open all year round.

That's why Dupont weatherization experts developed DuPont Weatherization Sealant. Flexible, durable, airtight and water-resistant, DuPont Weatherization Sealant is specially formulated to help protect vulnerable wall crevices from the elements, helping increase energy efficiency and comfort in your home.
