Spray Foam FAQ



What is spray foam?


Spray foam is a chemical product created by two materials, isocyanate and polyol resin, which react when mixed with each other and expand up to 30-60 times its liquid volume after it is sprayed in place.


What are the differences between open and closed cell spray foam applications?


Open cell foam is full of cells that aren't completely encapsulated, the cells are deliberately left open. This makes the foam a softer, more flexible material.

Closed cell foam is made up of cells that are completely closed. The cells are pressed together, so air and moisture are unable to get inside the foam, because of this, closed cell foam is much more rigid and stable than open cell foam.


Do I need to leave my home during the installation process?


The area of installation will need to be cleared of children, pets and other workers/adults without protective gear until the home can be safely reoccupied.


Is spray foam insulation fire safe?


If a home has spray foam insulation in an attic or crawl space, the building code requires using materials or assemblies that offer some fire resistance but not as much as is required for a thermal barrier. If you've got spray foam insulation in an attic, for example, it's probably already separated from the living space by a thermal barrier. Most ceilings are made of 1/2" drywall. But the spray foam is still exposed to the attic and needs an ignition barrier.


Is spray foam insulation mold resistant?


Spray foam insulation can effectively seal roofs and other spaces where condensation is more likely. With Spray foam insulation, you can not only save money with energy cost but maintain the integrity of your home because molds and other outside elements can't possibly thrive inside.


Can having spray foam decrease my utility costs?


All of the benefits that spray foam insulation can provide can be summarized nicely by looking at the savings you can enjoy. With the increased energy efficiency of your home, you can save between 30%-50% on your energy bills.
