Do I need to be concerned about the odor from spray foam?

During the installation process of spray foam insulation there is a small amount of chemical compounds in the air, just like many site applied building materials.  Anyone in the spray zone during application should have the proper personal protective gear.

The material can give off vapors that may be noticeable by some people, however with proper ventilation and cleanup afterward it will disappear.  

Did you buy a home that needs an update for the insulation or a do you just want to update the insulation in your home where you have lived for some time? 

The good news is that spray foam insulation can be used in an existing structure, whether you are doing a renovation or just an insulation retrofit.  Spray foam has the highest R-Value per inch compared to other insulations, so there are certain applications in a home, such as cathedral ceilings and 2nd floor living space in Cape Cod style homes, where you want to meet a minimum R-value and don’t have much space available.  With spray foam insulation you are able to insulate properly.
