Building Paper

Building Paper

Building paper, also known as house wrap, is a material used in the construction industry to provide a protective barrier between the building envelope and the exterior environment. It is typically made from a combination of asphalt-impregnated felt, synthetic materials, or a combination of both. Building paper is designed to be water-resistant, vapor-permeable, and durable, making it an essential component in protecting the structure from moisture damage, air infiltration, and energy loss. Building paper is installed on the exterior of the building, typically over the sheathing and under the siding or cladding. It is applied in overlapping layers, with the seams taped to create a continuous barrier. The installation of building paper is an important step in the construction process, as it helps to prevent moisture from penetrating the building envelope and causing damage to the structure. There are several types of building paper available, each with its own unique properties and applications. Some types of building paper are designed for use in specific climate zones, while others are designed for use in high-wind or hurricane-prone areas. Building paper can also be treated with fire-retardant chemicals to improve its fire resistance. In addition to its protective properties, building paper can also improve the energy efficiency of a building. By reducing air infiltration and preventing moisture from entering the building envelope, building paper can help to reduce heating and cooling costs and improve indoor air quality.
