What is house wrap?

House wrap is a material that is used to protect a building's structure from moisture and air infiltration. It is typically made of a synthetic material such as polyethylene or polypropylene, and it is installed underneath the exterior siding of a building.

House wrap helps to create a barrier that prevents water from seeping into the walls of a building, which can lead to mold, rot, and other structural issues. It also helps to reduce air infiltration, which can improve the energy efficiency of a building by preventing heat loss and reducing drafts.

House wrap is typically installed over the sheathing of a building and underneath the exterior siding. It is important to properly install and seal house wrap to ensure that it functions effectively. It is also important to choose a house wrap that is breathable, to allow moisture to escape from the walls and prevent mold and mildew buildup.

Overall, house wrap is an important component of a building's envelope and can help to improve its durability, energy efficiency, and overall performance.
