No - spray foam insulation is not banned in Canada or Alberta. It's a code-recognized building material, manufactured to CAN/ULC-S705 and installed by certified applicators in homes and commercial buildings across the country. The 'banned' idea comes from a mix of misinformation and specific overseas headlines.
Where the confusion starts
- UK mortgage stories: some UK lenders became cautious about older open-cell roof-deck installs done poorly - a lending/underwriting issue in one market, not a product ban, and not the Canadian context.
- Bad-install horror stories: failed jobs (off-ratio, off-gassing) get shared as if the product is the problem, when it's the installation.
The Canadian reality
Spray foam is fully permitted here, governed by national standards, and required to be finished with a thermal barrier in living space. Done to standard by a certified installer, it's a mainstream, compliant choice.
