In this way, is house wrap necessary?

House wrap is a moisture barrier, but it is not 100% waterproof. If it is directly exposed to water for too long, that water can get through. Since it is underneath the exterior siding of a home, being completely waterproof is not required.

Likewise, how do you use a Tyvek house wrap? To install Tyvek, start by positioning a roll at the first stud on the outside wall, leaving a 12 inch overlap around the corner of the house. Then, unroll the Tyvek and secure it with nails every 12 inches along each stud.

Keeping this in consideration, what is the purpose of a house wrap?

Housewrap (or house wrap), also known by the genericized trademark homewrap (or home wrap), generally denotes a synthetic material used to protect buildings. Housewrap functions as a weather-resistant barrier, preventing rain from getting into the wall assembly while allowing water vapor to pass to the exterior.

Is Tyvek the best house wrap?

Originally, asphalt-laden felt paper was thought to be the best type of house wrap on the market. In fact, it's still available, along with other house wrap solutions. However, Dupont's Tyvek HomeWrap® is considered by most in the building profession to be the industry leader.
