Spray foam insulation isn't asbestos if installed properly. Canada requires manufacturers to test chemical composition and installers to apply foam in 2-inch passes with specific ventilation: 0.3 air exchanges per hour for 24 hours before reentry.
We've been seeing some concerns online with people talking about spray foam and having some concerns with it being in their home. Some people are even comparing it to the new asbestos. Today we want to talk about safety with spray foam. What we want to talk about today are some standards that we follow to make sure that every install is going to be done safely in your home. The first one we'll talk about is the S705.1. So this is the CAN/ULC S705.1. It's done by the Underwriters Laboratories of Canada, which is a third party to the government. So it's not governed by the government, it's just overseen by them to make sure that there's no conflict of interest. Now what the S705.1 dictates is the manufacturer standards, so it makes sure that the manufacturer who's making our products is held to a really high standard. So they're tested for the contents of the foam to make sure that the quality of the foam is tested and is going to perform for your house. The other side of that is the S705.2, and that's where we come in. So that's for the actual application. That makes sure that once we're installing the product, it's getting done properly and leaving your home safe. The contents of that are doing 2-inch passes, making sure that we have proper ventilation time. So we need to have 0.3 air exchanges per hour for 24 hours, and after that, the house is completely safe to enter.
