Cape Cod Home – condensation on LL floors – mid-May through mid-September
Cape Cod Home – condensation on LL floors – mid may thru mid september… the basement is walk out with windows, slider, so a fair amount of air goes through.
I do understand the floor is colder than the air flow temp. The key piece of info is that there is no insulation under the concrete floor.
The real question…. can a layer of foam be put down over the concrete and then a sleeper floor over that ?? or simply the sleeper floor ? what is the correct way to mitigate that condensation problem on some level.
Also do not want to trap moisture and cause mold … (ie plastic … or foam that is not thick enough).
We have 2.5 inches of working space until slider would need to be raised.
Old timers… say build a dead floor. (sleeper floor). leave a space for air flow at the edges for the condensation and water vapor to dissipate … ” their words ..”you will likely never stop as long as doors and windows will most likely be open”.
Slider is open 80% of the time… as people use that entrance and exit …
