What’s the Use of a House Wrap?
When installed for slowing winds, house wraps seal leaks and gaps in the plywood sheeting or your home’s exterior walls. It prevents drafts from reaching the insulation. Also, it helps in keeping cooled and heated air from escaping through the walls. While your siding protects your home against harsh elements, there are different types of gaps and cracks in the joints where siding panels align. That can result in air leaks, which can increase heating and cooling costs.
Meanwhile, when used as a moisture-barrier, house wraps offer protection against rain, snow and moisture. Moisture barrier house wraps are usually made with permeable materials that let water vapor pass through them while keeping out water droplets. It keeps the surface dry to prevent the formation of mold.
