We have been using Superior Walls for basements for years with great results. The XI (extra insulation) wall system provides an exceptional water, thermal, and air barrier which helps us to achieve high performance in our homes. If you are worried about cold, damp, musty basements with water issues, remember, IT DOESN'T HAVE TO BE THAT WAY! We make basements that are as comfortable as the rest of the house. That means extra usable space for a fraction of the cost!
