The insulation has made visiting the house so much more comfortable.. we had the walls spray-foamed, and now a little space heater keeps the whole house well above freezing. After many discussions and visits by five(?) different insulation contractors, we settled on Icynene spray foam, and Advantage Insulation. Icynene is made of castor oil, is sprayed without propellants, and doesn't settle over time. There is some off-gassing initially as it cures, but all off-gassing stops after 24 hours. We are so happy with our decision!

The exterior walls were all sprayed, and the ceiling is insulated with formaldehyde-free fibre glass
