Foam and water do not mix.
Should you insulate concrete basement walls.
Closed cell spray foam is the best way to insulate concrete basement walls.
Foam insulation for instance is a common material for basement walls.
Concrete rubble mortar and brick especially older brick can be susceptible to damage in the freeze thaw cycle.
Shouldn t i insulate my basement freezing damage another factor is the potential for freezing damage.
Many people will argue that basement insulation is not important because the foundation temp stays a constant 55 degrees and the wind does not blow 8 feet underground.
Uninsulated the finished wall will be cool cold.
The answer is yes you should.
That s because any insulation you might install on say the walls would potentially get ruined with excessive moisture.
I still believe you should insulate when you finish your basement.
Basement walls made out of concrete stone concrete bloc and other masonry foundation materials have very minimal insulating properties and cause approximately 20 of heat loss in a home.
Insulation materials are the key the key to successfully insulating basement walls is selecting insulating materials that stop moisture movement and prevent mold growth.
An excellent question.
If you insulate the foundation the outside will be colder.
It can fill in all the gaps and spaces thoroughly giving you the best protection against moisture and air infiltration.
Because they are naturally located below ground level basements are mostly cool and damp.
So you must assume that your concrete is fully saturated and full of water in order to properly insulate your basement walls.
This is because it can achieve a higher r value along with excellent moisture resistance with less thickness required.
