Managing Moisture
Thinking of building a timber home? Remember to mind the moisture.
“The optimum moisture level for a home is 40 to 45 percent,” says Larry Kruse, co-owner of Vermont-based North Woods Joinery. “But 60-70 percent is typical in the first year, whether the home is timber or stick built.”
Why so much moisture? Because wood-like other natural products-contains a lot of water. Ditto the materials that go into building a home, including paint, concrete and drywall mudding. As moisture outgasses from these substances, it enters the air. Hence, the dampness.
Moisture levels will decrease over time, but meanwhile, use a dehumidifier.
This past winter, home owner Joshua Durst ran his dehumidifier for two weeks in his timber home.
“I probably pulled out 20 gallons of water,” he says. By spring, however, his home’s humidity level had stabilized at a comfortable 40 percent.
Wondering how your home’s moisture level measures up? Buy a digital hygrometer thermometer-it measures temperature and humidity levels. It’ll run you about $30, and the credit-card sized gadget can be mounted out of the way in a closet. – H.S. |
