1. Remove anything that will get in the way of installation. Cut the STYROFOAMâ„¢ extruded polystyrene insulation panels to the length needed to cover from the top of the footing to the top of the foundation wall.

2. Apply a bead of foam compatible adhesive in a rectangular pattern on the the back of the STYROFOAM insulation board and press the insulation to the wall. The adhesive will hold the insulation in place while you next install furring strips.

3. Attach 1"x3" or 2"x3" wood furring strips vertically or horizontally over the foam insulation at 16" or 24" on center. Use Tapconâ„¢ or other fasteners for concrete. Fasteners should penetrate at least 1.5" into the concrete. Fasteners should be spaced no more than 24".

4. A thermal barrier consisting of 1/2" gypsum drywall must be installed over the insulation. Use the wood furring strips as a fastening base for the 1/2" gypsum drywall.

5. A ground cover must be installed to reduce moisture levels in the crawlspace. The ground cover should consist of a minimum 0.006 inch polyethylene sheeting. The edges of the ground cover must be sealed to the crawlspace wall. The joints in the ground cover must be lapped a minimum of 12" and sealed and weighted down. An alternative to sealing and weighting down is the installation of a 2" concrete skim coat over the ground cover.

6. Crawl spaces may require ventilation. Consult your local building code for specific requirements.

7. Insulate the inside of the band joist with either fiberglass batts with vapour retarder facing to the inside of the crawl space or with pieces of foam cut to fit tightly, covered with gypsum drywall adhered to the foam pieces.
