Insulating a heated basement

There are two ways to insulate basement walls. If the masonry walls are too irregular to attach a finished wall directly to them, build a free-standing conventional stud wall against the masonry foundation and then install fiberglass bats between the studs. If the walls are generally straight (like masonry block walls), then you can simply glue rigid foam insulating panels directly to the foundation walls between a framework of vertical wood furring strips installed on the wall about 24" apart. To fasten 1" X 2" or 1" X 3" wooden furring strips to the masonry walls using Loctite® Power Grab® Heavy Duty Construction Adhesive:

Step-by-Step Directions

    

Apply a continuous bead to the back of the furring strip and press in place.

    

Loctite Power Grab’s Instant Grab insures the furring strips remain in place with minimal need for bracing, making installation quick and easy.

    

Repeat until all furring strips have been installed.

    

Pre-fit the foamboard insulating panel and then apply a continuous 3/8" bead of Loctite Power Grab Foamboard Adhesive on the foamboard, ½" in from the edge and down the center. Press firmly to the wall.

Tips

  • To make your newly-insulated basement space look more like conventional rooms, the foamboard insulation should be covered by drywall or pre-finished paneling. Use Loctite Power Grab to fasten the panels to the furring strips.
