LIQUIDARMOR CM Flashing and Sealant Dow Chemical Company Designed to provide commercial buildings with moisture- and air-sealing protection, this sprayable, water-based coating covers and seals gaps as large as a quarter inch wide. It’s suitable for a range of surfaces, such as tapes, wood buck, and foam boards. R-Guard SureSpan EX PROSOCO A high-performance silicone material consumes both thermal movement and wind-loading stresses. It creates a long-lasting, flexible, and elastomeric seal that connects air and water barriers with building curtain walls, storefronts, or windows. DuPont Tyvek ThermaWrap R5.0 DuPont Providing air, water, and thermal protection, this breathable weather barrier is equipped with six-inch uninsulated fl aps that can be installed like shingles.
