The inorganic materials that make up ZenWall — fiberglass, foil and vinyl, are all inorganic and will not rot or support mold growth, unlike the concrete walls in the before picture. It can also make up to a 10 degree difference in the surface temperature of the wall, adding comfort and saving energy. Aside from all of these benefits, ZenWall panels can be installed in any basement to make your walls look great! They dramatically brighten the room.
