Spray Foam Insulation FAQs

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.

  • Density: Closed-cell foam is denser than open-cell foam, with a density of 1.9 pounds per cubic foot or more, while most open-cell foam has a density of about .5 pounds per cubic foot.
  • R-Value: Closed-cell foam has about twice the R-value of open-cell foam insulation. The R-value of insulation is its resistance to heat flow or, in other words, how well it insulates.

  • Superior insulation performance: Spray foam has a higher R-value than BATT insulation, which means it provides better insulation per inch of thickness. This helps to prevent heat transfer and keep the building comfortable and energy-efficient.
  • Seals air leaks: Unlike BATT insulation, which can leave gaps and air leaks, spray foam fills every nook and cranny of the space, creating an airtight seal that reduces energy loss and prevents moisture infiltration.
  • Energy efficiency: Spray foam insulation is known for its superior energy efficiency compared to other insulation types, including batt insulation. It creates an air-tight seal that prevents air leaks and reduces energy loss, leading to lower heating and cooling costs over time.
  • Moisture resistance: Spray foam is impermeable to water, which makes it resistant to mold and mildew growth. This helps to protect the building from moisture-related damage and improve indoor air quality.
  • Long-lasting: Spray foam insulation has a longer lifespan compared to BATT insulation, which can sag or compress over time. It remains effective for many years, providing reliable insulation and energy savings.
  • Versatile: Spray foam insulation can be applied to a wide variety of surfaces, including walls, roofs, and floors. It can also be used in new construction or retrofitted into existing buildings.
  • Noise reduction: Spray foam insulation can also help to reduce noise transmission, making the building more comfortable and quieter.
  • Allergens and pollutants: Spray foam insulation can be beneficial for those who suffer from allergies and respiratory issues. It forms an air-tight seal that keeps out dust, pollen, and other allergens and pollutants, whereas batt insulation can act as a trap for these particles.

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.
