There has been some controversy lately over the safety of Polyurethane Spray Foam. It has become clear in recent months (maybe years) that spray foam in houses is not always a good idea. Foam off-gasses at the time of installation, and people should avoid the spray area for a minimum of 24 hours after install. Many homeowners, contractors, and some spray-foam companies do not abide by these rules, and potentially risk their health by doing so.
I am not against the use of spray foam in construction. I estimate and sell many spray-foam jobs every year. I don't, however, recommend it as the sole insulation in a new home or cottage. It is the very best option for sealing up the floor of a cottage on piers from below and insulating timber-frame roof areas from outside. Framed walls, and ceilings are better insulated with chemical free materials that absorb sound and cost less.
My preference is the Blown-In-Blanket System (BIBS) or Blown In Insulation System like Pro-Pink.
These systems use virgin (chemical free) fibreglass blown into each specially prepared cavity to make a seamless "blanket" of insulation in your walls and sloped ceilings. I recommend loose blown material, usually fibreglass, for flat attics. Regular 6mm poly is installed as vapor barrier.
This type of system is slightly more labor intensive than installing batts, but provides vastly superior results in real life construction. Cathedral Ceilings, Rim Joist areas, Walls, and Sound Floors are where the BIBS system shines. Good value for your dollar vs spray-foam, and no worries about fire-proofing, off-gassing, and huge costs. Since this type of system requires well-trained, specialized installers, Thermo Seal Insulation has a huge advantage over companies that have only started using BIBS in recent years. Thermo Seal Insulation Systems pioneered the system in Canada, and has more BIBS installs than any company in the country.
