Anair barrier, situated on the exterior of the building envelope, acts as a shield against the infiltration of air through the structure. It can be fashioned from various materials such as house wrap, plywood, or gypsum board sheet products. In contrast, avapor barrier, located on the interio...
buildings, either alone or in combination with other types of insulation. Unlike some other common forms of insulation, Radiant Barrier requires a small airspace in order to be effective. Once installed properly, Radiant Barrier is extremely effective, blocking up to 97...
However, this type of insulation can settle over time, reducing its R-value. Spray foam is an insulating option that can be installed by a professional or DIYer. It consists of a two-part liquid that expands into a foam upon curing. It acts as both an insulator and air barrier and ...
Terms such as “vapor barrier” or “vapor retarder” are familiar to most of us, even though we may not be completely clear on their differences. They describe a material’s vapor...
(a) health or safety of building users, (b) the intended use of the building, or (c) the operation of the building services. The research demonstrated the ability of typical framed walls using spray polyurethane foam insulation, with and without additional vapor ba...
A vapor barrier for sealing an interior of a building from an insulation cavity defined by framing members of the building includes a flexible and substantially impermeable sheet ha

In a fire, the side of the fabric with the intumescent coating expands to create a char barrier. The char helps to protect against the conductive penetration of hot gasses and flames. It can also absorb smoke into its matrix, thus lowering by-products from the fire. It reduces the flame ...
