Spray foam insulation is a product that is applied by certified installers using specialized equipment. The two most common types of spray foam used in buildings are open-cell (OCSPF) and closed cell (CCSPF). Choosing what type of spray foam to use depends on both the application and the budget. The primary benefits of spray foam insulation are that it can act as both a thermal barrier and an air barrier when properly designed and installed.


Open Cell spray foam is an economical spray foam solution, ideal for main living space walls, as well (due to the open cells) this foam can create an excellent sound barrier between interior walls and/or floors. Open Cell spray foam becomes an air barrier, eliminating drafts that can exist with traditional batt insulation. With Open Cell spray foam, you will still require the installation of a vapour barrier.


Closed Cell spray foam is a premium solution with many applications. All exterior walls, basement walls, cathedral ceilings, exterior applications, and more. With an R value of greater than 6 per inch, Closed Cell spray foam reduces the amount of material required to increase your homes insulation, and after just 2" the Closed Cell foam becomes an air and vapour barrier.


Batt insulation is the most commonly found insulation in homes. It comes bagged in pre-cut lengths and widths which the installer places manually into the wall cavity. Batting insulation is not an air barrier and requires a vapour barrier be installed on the warm side of the buildings envelope to resist moisture movement. The two most common batting insulation types in our climate are Roxul and Fibreglass. The primary benefits of batt insulation are it’s upfront affordability, wide availability and sound dampening properties.


Roxul is a rock-based mineral fibre insulation with fire, moisture, sound and thermal resistant properties. Roxul is a great option due to its’ higher fire resistance and sound dampening properties.


Fibreglass batting was the most commonly used product within the building industry of the past. It comes in a variety of R values, widths and thickness to fit with any building assembly. Choosing when to use fibreglass depends on both the application and the budget.


Wetted fibreglass insulation offers smaller fibers to fill tight spaces around pipes, wires, electrical boxes and other wall cavity obstacles. While comparable in price with traditional insulation, the wetted solution fills the wall cavity and removes the manual installation, while insualting the wall just as well.


Reducing the amount of air that leaks in and out of your building is a cost-effective way to reduce heat loss and cut energy costs, improve durability, increase comfort, and create a healthier indoor environment.
