At Red Isle Spray Foam, our goal is to educate our customers on the benefits of spray foam and how to take advantage of it to leverage their savings each month. Our professional opinion and expertise is based on half a century of insulation science based in the foam industry. If you’re wonder where to start first with spray foam, we recommend having a thermal image assessment of your home to find the cold zones and correct those specific areas first. Next, you’ll want to evaluate your attic or roof insulation, check to see whether or not your air-vapour barrier is taped and sealed and measure the amount of insulation. Over 40% of heat loss occurs in the attic because heat rises. Following this, check your wall and floor insulation for a sealed air-vapour barrier and the proper amount of insulation. And then do the same for your basement.

What is Spray Foam?

Spray Foam is a short form of the main term “Polyurethane Spray Foam”, and it’s also abbreviated in the industry as “PSF Insulation”. Depending on the formulation polyurethane foam can be sprayed or poured. Poured foam is generally seen in industrial applications, and sprayed foam is seen in residential, commercial, and agricultural settings.

Polyurethane Spray Insulation

PSF Insulation is made up of two chemicals, the iso side and the resin side. Iso would be like the glue that holds foam together, whereas resin would be the unique mixture that gives foam its properties. Resin is primarily polyol with a list of elements such as a catalyst and HFO blowing agent, among trade secret chemical formulations to achieve the desired r-values, thermal performance, reaction time, and smoothness of application.
  • A-component is the isocyanate
  • B-component is the polyol resin

The two chemicals are filtered several times, removing air and filtering particulates before entering the guns mixing chamber. It only takes a second for the reaction process to take place and expand.

Spray Foam Safety

Spray foam is a very safe product once in its inert state, or fully cured state. Until it reaches this point the spray foam will continue to cure and off-gas. These fumes need to be vented out of the building for at least 24hrs. Our applicators use air filters, and fresh air-supplied units to keep our installers from breathing these fumes. Touching spray foam in its fully cured form is completely fine, if its uncured make sure to wear the proper PPE.

Is Spray Foam Common in Atlantic Canada?

Yes, spray foam is very common in Atlantic Canada, it’s been here since at least 1960. Many homeowners and architects choose to insulate with spray foam because of its significant return on investment. It’s a larger investment upfront but it is quickly regained within a few years. It’s ability to last over 50 years is why it’s so popular as an insulation choice.

Open-Cell vs Closed Cell Spray Foam

Open-Cell Half-Pound Spray Foam

Open-cell spray foam is generally used for light or non-insulation purposes. It’s primary use would be an insulation option for warmer climates, filling voids, cracks, and large cavities. The “open” part comes from the way the foam is connected because it looks like a 3D spider web with air being able to flow in and around the microscopic foam structure.

Closed-Cell 2lbs Spray Foam

Closed-cell spray foam is generally used for sealing and insulation purposes. It’s primary use would be an insulation option for mild to cold climates, and for creating air-moisture seals. The “closed” part comes from the way the foam is connected because under the microscope it looks like a bunch of closed bubbles with air trapped within them.
