What Is House Wrap?

In construction, air and moisture infiltration can’t always be avoided—it’s impossible to protect a home from all the elements. But house wrap has helped control the problem and is used today for a large number of homes.

Many homeowners, however, don’t know exactly what a house wrap is.

What Does House Wrap Do?

So, what is house wrap and what does it do? House wraps, also referred to as housewraps, prevent moisture, mold, and drafts from entering your home and can act as a strong barrier against moisture or wind. House wrap is especially useful in humid climates that receive a lot of rain because it can prevent damage from water penetration.

What Is House Wrap Made Of?

House wrap is a synthetic material that has come to replace asphalt treated paper—this lightweight material is installed over the sheathing and behind the siding. Basically, house wrap is the home’s last line of defense against air leaks, water infiltration and leaks, etc.

This thin but resilient material functions as a weather-resistant barrier, preventing rain from getting into the wall assembly while allowing water vapor to pass to the exterior. If sealed carefully, it’s also effective as an air barrier for homes.
