This split level home in Springfield had cold basements as there was no insulation in the walls.
The injection foam rig/trailer. We have to carefully mix the 2 part foam and get the flow correct before we start.
Close up of the rig. Notice the two big containers holding the 2 parts of the foam mixture.
Holes were drilled in each empty wall stud space.
More holes to inject the foam insulation into the walls.
Use of a fiberglass rod about 6 feet long helps us make sure the injection foam will spread behind the wall cavity.
Injection foam process takes 2-3 crew members. One to work the rig outside, one to insert the vinyl tube into the wall, and one to turn the foam flow on and off.
