What advantage does house wrap have over asphalt paper?

House wrap is favored over asphalt paper primarily because it is lightweight and significantly reduces the number of seams during installation. This characteristic is essential in providing better moisture management and air barrier capabilities. A seamless installation limits the potential points of water penetration or air leaks, enhancing the overall effectiveness of the building envelope in protecting against wind and rain damage.

The lightweight nature of house wrap also makes it easier to handle and install, allowing contractors to work more efficiently without the heavy lifting associated with asphalt paper. This ease of installation can contribute to faster project completion times. Furthermore, the reduced seams help to create a more continuous barrier, which is critical in maintaining the energy efficiency and durability of a structure.

In comparison to the other considerations, the advantages of seamless application and lightweight properties clearly highlight why house wrap is often preferred in modern construction practices.
