Is spray foam insulation safe for your home? Yes, when it's installed correctly. In Canada, spray foam must meet CAN/ULC-S705.1 material standards and be installed by certified applicators following CAN/ULC-S705.2. The final safety step is a proper spray foam thermal barrier, which protects the foam from heat during a fire. Without it, exposed foam can spread flame and produce toxic smoke. With it, spray foam is a safe, code-approved insulation used in thousands of BC homes every year.
