Safety concerns regarding spray foam insulation
I contracted with a company to install new insulation in the attic and crawl space of my home. I hired a local company, and due to ignorance and inexperience on my part I didn't ask questions regarding the product they would use.
They removed the existing fiberglass insulation from my house, and I assumed they'd replace it with a similar product. The installation occurred last Friday 10/5. I came home and immediately noticed a strong chemical smell.
I went up to my attic and saw that the entire ceiling, walls, and windows had been sprayed with spray foam insulation. It is now an unvented attic. I wasn't given any information/ brochure about the product beforehand. The odor was extremely concerning to me, and I did my research unfortunately after the fact regarding spray foam insulation.
I went to several sites including Green Building Advisor and the EPA. I learned about the toxic nature of the components, and that at a minimum we should not have been home during the spraying and for several hours afterwards. I have also read about off gassing. I am concerned about exposure my family and I have had so far since we were home during the application and immediately following it, and the risk of continued exposure. I am seriously considering having the spray foam removed.
1. Do you have any advice regarding spray foam insulation and its overall safety track record?
2. Would it be prudent of me to remove it? Or now that it's in place is it ok to keep it?
3. Does the installer have any obligations to disclosed the product safety concerns, and to advise on measures to minimize exposure before installing the product?
