Consequently, should you put plastic on basement walls?
Visqueen on Walls A common question people have when finishing a basement is: "Should I use visqueen or plastic sheeting on one side or the other of the framed basement walls?" The answer is no. Plastic will keep moisture from moving through the wall.
Beside above, what type of insulation should be used in a basement? The most commonly used insulation materials in the basement include spray foam, fiberglass, and foam board. In older homes, the basement many times is left uninsulated. This allows air from the outside to get into the rim joist, basement ceiling, and exposed walls.
Additionally, is vapor barrier necessary?
The purpose of vapour barriers A vapour barrier is an important component in building construction. Its purpose is to help prevent water vapour from reaching building walls, ceilings, attics, crawlspaces or roofs, where it can condense and cause building materials to rot or grow mould.
Should you insulate your basement walls?
Walls. Basement walls should be insulated with non-water sensitive insulation that prevents interior air from contacting cold basement surfaces—the concrete structural elements and the rim joist framing. The best insulations to use are foam based and should allow the foundation wall assembly to dry inwards.
