Foundation insulation strategies reduce moisture movement and energy loss
Home insulation strategies should include protecting below-grade walls and foundations from potential moisture damage and energy loss.
At the 2016 International Builders' Show, Brian Lieburn, residential applications technology leader for the Dow Chemical Company, reviewed some of the strategies for interior and exterior insulation of below-grade structures.
Lieburn noted that proper exterior continuous foam insulation systems can significantly reduce heat loss through concrete walls, resist hydrostatic pressure, keep crawl spaces dry, and protect against frost.
Insulating basement walls, including rim joists, helps increase the energy efficiency of both new and older homes and provides long-term thermal performance to warm the basement walls while also providing moisture-resistance to help prevent the “damp basement” feeling.
"To achieve these multiple objectives, it is important for builders and remodelers to regard each home as an overall system that should be insulated and sealed, including below-grade walls and foundations," Lieburn said.
