I heard that spray foam will make my house to tight and that the house needs to breathe?

How long does spray foam last?

Spray foam insulation will last as long as your home does and being that it is sprayed in place you will not have any sagging or settling of your insulation over time 

How is Spray foam Installed?

Spray foam insulation is sprayed in place by our trained professional spray foam insulation applicators. Spray foam starts off as two separate liquid chemicals that come in barrels located in our spray foam insulation trailer/truck. These two chemicals are  pumped to our specialized Graco portioning equipment that heats the chemicals, pressurizes them, and monitors the application process to make sure that the foam being sprayed is on ratio and processed to manufacturer’s specifications. The Graco equipment that we have choose to use to process spray foam has modern processing technologies that will shut down the machine if any parameters fall outside of manufacturer specifications during the  spray foam application process. This failsafe feature is not available on all spray foam processing equipment. We feel that having the most modern, high-end equipment, with extra Fail-Safe options, is well worth the peace of mind knowing that all our projects will be On-Ratio and meet the required manufacturer specifications.

What about the stud unions and gaps between lumber in the home?

When we bid a spray foam job we highly recommend sealing all stud unions in your building envelope to completely seal things up.
