Sealed Crawl Spaces 02.05.2015
Scientific research and built examples demonstrate how properly closed crawl spaces can provide much better moisture control than conventional, wall-vented crawl spaces in temperate-humid climates. Homes with closed crawl spaces–often called “sealed,” “unvented,” or “conditioned” crawl spaces–also can save significantly on energy when compared to homes with wall-vented crawl spaces.

Bizios Architect has been designing homes with sealed crawl spaces for years. The images below illustrate crawl spaces we have designed that are now providing better moisture control and energy-efficiency, contributing to better places for living.
