Flooring Options For Unconditioned Air

If a floor built over an unconditioned space isn t sealed to be airtight it can cause unwanted heat loss in cold weather and heat gain in warm weather.

Flooring options for unconditioned air.

Lvf installation that occurs over an unconditioned crawl space especially in warmer more humid climates can significantly slow down vapor under the floor and increase the risk of condensation. Lvf installation that occurs over an unconditioned crawl space especially in warmer more humid climates can significantly slow down vapor under the floor and increase the risk of condensation.

A semi conditioned space is not conditioned to the same degree as indoor air but it s not as cold or hot as outdoor air. Removal would be the best way to adequately air seal the attic floor so moving the air and thermal boundary to the roof line is the better option.

An unconditioned space is not heated or cooled so it s the same temperature roughly as outdoor air. The most common types of floors that have to be insulated and air sealed include cantilevered floors floors over garages and floors above unconditioned crawl spaces.
