Rigid Foam Insulation On Basement Concrete Walls

I ve read basement insulation systems a research report c 2002 by building sciences corporation.

Rigid foam insulation on basement concrete walls.

Attach the tongue and groove insulation boards to the concrete wall with adhesive. We are going to finish the basement and remove all of the old insulation we ve seen some small skinks lizards hiding in there as well as on our porch and we want to use xps boards along the walls before studding out and drywalling. How to glue polystyrene insulation to a concrete wall. Styrofoam brand insulation is a rigid insulation that can be placed directly on walls framing and drywall.

There is almost. Any of the following insulation materials are acceptable for this purpose. When insulating interior basement walls in a finished basement use our styrofoam brand insulation. Closed cell spray polyurethane foam or either xps eps or polyisocyanurate rigid foam.

My basement has some old insulation above the frost line as well as some 2x4s nailed down to the concrete walls. After that thin furring strips are installed on top of the foam to provide a firm base for the drywall screws and drywall but can you run rigid foam between the studs just as you would do with fiberglass rolls or spray foam. Their diagrams indicate foil faced polyisocyanurate rigid foam or xps for insulating the rim joists and the top of the concrete foundation wall then xps rigid foam on the concrete wall face. For a basement remodeling project consider insulating basement walls with foam board.

Polystyrene foam boards commonly called foamboard are a clean lightweight convenient way to insulate bare concrete walls. The correct method of using rigid foam is to run continuous 4 foot by 8 foot sheets of the foam across the concrete basement wall making the rigid foam the de facto wall. Use a premade kit for this type of project. For new construction use rigid boards to insulate slabs and the outside of foundation walls.
