Green Bear Spray Foam

NOT all spray foam materials are created equal!

There are many different aspects to a properly applied spray foam product including it’s material makeup, application procedures and temperatures and also many other variables.

One major issue with soy-based spray foam insulation is the potential for shrinking. Due to some major research and product development breakthroughs shrinkage of spray foam is becoming less of a headache for spray foam installers and materials manufacturers.

Take a look at the pictures that are provided with this post. It is an image of spray foam applied to the roof deck in an attic space. There are many areas in this particular attic like this and most of them are in areas that have the hot sun beating down on the roof deck for hours every afternoon.

Though this is not a common occurrence, it is much more common on roof decks than any other area of a home. As stated, breakthroughs in the makeup of soy-based spray foam materials have virtually eliminated this occurrence.

If this happens to you…who is responsible? The spray foam installation company, the foam materials manufacturer…? Let us know your opinion, we appreciate it!
