Spray Foam Insulation Safety

While the efficiency of your home or building is of utmost importance, our chief concern is the safety of your family or the building occupants. While you may hear different things from different spray foam companies regarding spray foam safety, the requirements are clear. No person(s) will be allowed to occupy the building during the Spray process and for 24 hours after completion. This requirement falls under the CAN/ULC s705.2 and all spray foam companies must comply. Once the install is complete and the 24 hours has passed, the occupants can return. The spray foam is inert and safe to be around.
