Spray foam and fire protection
Hello, I have been asking various people about the following and am getting many different opinions. I understand that sprayed in place foam needs to be covered with a building material to provide a fire retarder, usually approx 15 minutes.
My question is, "is there any type of sprayed on foam insulation that will not ignite when exposed to an open flame?" I did watch a television program that showed a sprayed foam installed to the ceiling area between the floor joists in a basement. They held a torch to the material and it did not burn. Does this material need to be covered if it is installed in a area that people live?
Thanks for any input. Dave.
