Do You Need A Vapor Barrier In Basement Walls. Dedicated vapor barriers have no place in a basement wall. Ensure that the measurements are accurate so that the wall is fully protected.
This barrier is meant to keep moisture from getting to the insulation after the insulation is in place you will want to add a vapor retarder, sometimes called a vapor barrier, if you need one. The laws of physics trump code. I've done a lot of research on this one.
Where it is located in an assembly and its permeability is a function of.
Do you need a vapor barrier under a concrete slab? I've done a lot of research on this one. Water damage can be very costly to repair because it can damage measure the size of the walls that need vapor barriers. So i already framed a wall and know i should have put a foam board against the concrete but i didn't know that when i did it.
