This is our page for showing how to solve difficult insulating problems with foam insulation. We have solved hundreds of difficult problems, but never realized we should photograph them beforehand. Bear with us. We will add additional pictures to this page as quickly as possible. But, since a picture is worth a thousand words, we think you'll get the idea from the "two thousand words worth" of pictures shown below:
BEFORE : With traditional insulations, this area would be impossible to insulate.
These BEFORE and AFTER pictures below demonstrate the amazing ability of our sprayed expanding foam to fill those hard-to-reach places that traditional insulators can't reach. In the BEFORE photo (above) a band joist is inaccessible because a floor joist was only 1/4" from the top plate of the wall. Cold air would leak into this area unchecked for as long as the house was standing. We explained to the owner how we could fix the problem with Foam Insulation, and he was eager to have us give it a shot (literally!). He even drilled a few holes for us as shown.
In the AFTER photo (below) you can see the results when we sprayed Foam Insulation into the opening. Within 10 seconds the foam expanded, completely filling the band joist cavity, and the excess squirted back out through the crack and the holes at our installer. When the excess foam shoots back out the holes, it is proof that the cavity is completely filled and insulated. And that one more difficult insulation problem has been solved...with sprayed foam.
AFTER : Problem solved...withFoam Insulation!
You can imagine the number of places in a home where the expanding nature of spray foam would be beneficial. Just a few are:
