Insulating older homes is an all-or-nothing proposition. Just blowing insulation into the walls can create moisture problems that will rot the wood structure from the inside out.

Product Trends: Wrapping Up Energy

Housewraps regulate the amount of air-based moisture that travels in and out of the home, which can be up to 2,000 times as much as through diffusion. If the water can’t pass through walls as easily, it can get trapped there, eventually leading to mold, mildew, and rotting inside the wall.

Housewraps are the best resource for keeping a home warm and dry—and saving money in the process.
