How To Remove Spray Foam Insulation

Spray foam insulation is typically only removed during a remodel or prior to the installation of a new material. Removal of this insulation is a difficult task, and is best left to the professionals.

Removing Spray Foam Insulation

It should be known that removing this form of insulation is certainly no easy task. The properties that make this such a quality insulation are the same that make it difficult to remove. Spray foam insulation will expand upon insulation, forming tight seals and eliminating all voids to create an impenetrable barrier.

When installing and removing the insulation, safety is paramount. Always wear protective clothing and masks during these processes.

Step 1. Wear protective gear, including a mask.

Step 2. Cut the insulation with either a knife, saw or claw hammer.

Step 3. Tear the insulation away from the spaces it was installed.

Step 4. Repeat the second and third steps until the majority of the insulation has been removed.

Do not use any water on this insulation, as it will only make the material harder. Using heat in order to melt or burn away the insulation will also not work. It is extremely dangerous to attempt to use heat for removal.
