What is meant by building paper in the context of construction materials?

Building paper refers to a general term for various sheet materials used in construction. It encompasses a wide range of products, including roofing felt, house wraps, and rain barriers, which are essential for providing weather resistance and enhancing the durability of building structures. These materials are critical in both roofing and wall applications, as they help manage moisture, prevent air infiltration, and improve energy efficiency.

In the context of construction, building paper is utilized to create an additional layer that protects the structural components of a building from water damage and other environmental factors. Its versatility allows it to be adapted to various parts of the construction process, particularly in the roofing and siding installations, making it a fundamental element in ensuring long-lasting construction.
