Moisture Control in Your Home
Properly controlling moisture in your home can improve the effectiveness of your air sealing and insulation efforts—which will in turn help control moisture. The best strategies for controlling moisture in your home depend on your climate and how your home is constructed. Proper ventilation should also be part of a moisture control strategy.
What contributes to moisture in your home
Before you decide on a moisture control strategy, it helps to understand that moisture or water vapor moves in and out of a home in three ways:
- With air currents—accounting for more than 98% of all water vapor movement in buildings
- By diffusion through materials
- By heat transfer
