Moisture Control

Properly controlling moisture in your home will improve the effectiveness of your air sealing and insulation efforts, and vice versa. Thus, moisture control contributes to a home’s overall energy efficiency.

The best strategy for controlling moisture in your home depends on your climate and how your home is constructed. Before deciding on a moisture control strategy for your home, you may first want to understand how moisture moves through a home.

Moisture control strategies typically include the following areas of a home:

• Attics
• Foundation
  • Basement
  • Crawl space
  • Slab-on-grade floors
• Walls.

In most U.S. climates, you can use vapor diffusion retarders in these areas of your home to control moisture.

Proper ventilation should also be part of a moisture control strategy.
