Spray foam insulation is one of the most efficient ways to insulate your home. It has a higher insulation rate than other options, such as fiberglass and organic insulation, making it an ideal choice for those looking to reduce their energy bills. Homes insulated with spray foam can be some of the most comfortable and energy-efficient homes ever built. I have been to many of these homes and can attest to their superior performance compared to homes with fiberglass block insulation.
However, spray foam insulation isn't without its drawbacks. One of the main issues is that it requires ventilation, so completely sealing the attic isn't a good idea. Additionally, when open-cell spray foam insulation is installed at the bottom of the OSB ceiling covering, it can sometimes get wet. This can lead to the release of amines, which are derived from ammonia and can produce a fishy smell. In Canada, all foam systems must be tested by independent laboratories accredited by third parties to demonstrate that their physical properties meet the established ULC standards for the comparative performance characteristics of the final cured product.
This ensures that homeowners are getting a quality product. When deciding to install spray foam insulation, there are several factors to consider. It's important to get referrals and do your research when looking for a spray foam contractor. Additionally, closed-cell spray insulation is recommended for attics and ceilings, while rigid insulating foam may be a better choice for carved stone bases.
