Welcome to Classic Spray Foam FAQs page, where we answer some of the most commonly asked questions we receive about our services. We understand that choosing the right insulation for your property can be a daunting task, which is why we have put together this page to provide you with the information you need to make the right informed decision.
R-value is a measure of an insulation's ability to resist heat traveling through it. It tells you how well a type of insulation can keep heat from leaving or entering your home. R-values vary based on the type, thickness, and density of the insulation material, with a higher insulation R-value usually indicating better climate control and energy efficiency for your home.
Open-cell and closed-cell spray foam are two different types of insulation materials. Open-cell foam is made up of tiny foam cells that are not completely closed, which allows air to fill up the spaces inside. Closed-cell foam, on the other hand, has cells that are completely closed, so they are filled with a gas that expands during the insulation process.
Spray foam insulation is a polymer material that expands and solidifies once it's sprayed. It creates a durable layer of insulation in the walls and ceilings of your building, sealing gaps and cracks that traditional insulation might miss. There are two types of spray foam insulation: closed-cell foam insulation (CC) and open-cell foam insulation (OC).
Yes, spray foam insulation's ability to air seal helps greatly with airborne sound transfer. It works great for sound control in combination with other insulation materials. However, significant sound transfer happens mechanically through the building structure, so building design is also important for sound deadening.
Most brands of foam are essentially the same. They all have similar R-values, are air and vapour barrier materials, and significantly increase the “tightness” of the building envelope (it doesn’t leak air).
However, our 2lb spray foam contains a revolutionary new blowing agent, which is the ingredient in spray foam that gives it a high R-value. The blowing agent in our spray foam is called Solstice. It has a Global Warming Potential (GWP) of 1. All other spray foam manufacturers in Canada use the 245fa blowing agent, which has a GWP of nearly 1000.
