Tips on Attaching Insulation Panels to Concrete Block Walls

Finishing a basement creates more living or environmentally controlled storage space in your home. Basement walls are commonly made of concrete, which is a porous material that is not adept at keeping out the cold. Foam insulation panels are ideal for a basement remodeling project because they are waterproof and can help reduce heat loss through the concrete walls in the basement. Proper foam panel installation helps to maximize the insulation’s effectiveness.


If you have leaks in your basement walls then you need to eliminate those leaks before installing foam insulation panels. Adhesive used to install panels cannot cure properly when it is wet, and water trapped behind foam insulation panels can create a mold problem. Any cracks or noticeable leaks in your foundation should be repaired by an experienced contractor. Once the leaks are repaired you should coat your walls with a basement water sealer.


Insulation panels can be fastened to your concrete block walls using adhesive or fasteners specially designed for installing panels into concrete block. You can purchase foam board adhesive or construction-grade adhesive from your local home improvement store. Fasteners make it easier to remove the panels later if you decide to change your basement design, but adhesive can create a tight bond that can do a better job at regulating your basement temperature.

Uneven Surface

Whether you use fasteners or adhesive, you will need your concrete block basement walls to be as flat as possible prior to installation. Foam insulation boards need to be able to sit flush with the entire surface of your basement walls to be efficient. Rent a concrete surfacing grinder from a construction tool rental facility and smooth your walls prior to installation. Always wear protective goggles and gloves when using a concrete surfacing grinder.

Furring Strips

Furring strips are 1/4-inch thick wooden strips that can be attached to your concrete block walls with adhesive to allow installation of foam panel insulation with nails. Some homeowners prefer furring strips because basement wall frames can also be attached to the strips during a basement remodeling project to allow additional stability to the walls. If you intend on using furring strips to install your foam insulation panels, you need to be certain that moisture does not collect on your basement walls under any circumstances.

Basement insulation will save money on heating and cooling your new basement living space. When you install insulation panels to a concrete wall, be sure to follow the proper procedures to get the maximum energy efficiency from your basement remodeling project.
