Spray Foam Insulation
Spray Polyurethane Foam
Spray foam insulation is recognized as the most cost-effective, versatile and insulation-effective material in the market. Providing air sealing and a higher R-value per inch, spray foam is a better option than any other insulator material. This material solves most of the homeowner issues around their homes since it will expand up to 30 times its liquid state, filling and sealing every possible crack or fissure through the building creating a continuous envelope.
How does it works?
Spray foam insulation, also known as spray polyurethane foam insulation, is a product that is applied with two-component sprayer equipment that mixes both components simultaneously while they travel from the gun to the substrate. When both components reach the substrate, the mixture will expand up to 30 times its volume and solidify.
There are many types of spray foam insulation, the most common ones are 2 lb or ½ lb. Names depend on their density and have different properties. Two-pound spray foam has an R-value of 7 approximately, and half-pound is about 3. Two-pound will act as both air and vapour barrier, will stop water leaks and will add some strength to the structure. Whereas half-pound has a lower R-value, it does not provide air or vapour barrier, however, helps as sound dampening.

One added bonus of spray foaming along the roof (rather than the floor of an attic) is that the attic becomes climate-controlled storage by making that space more comfortable and freeing up your attic floor that will no longer be covered by traditional insulation. It is also shown to prolong the life of your HVAC air handler (if the air handler is in the attic) by preventing exposure to temperature extremes.
In both cases, we recommend using spray foam. However, on renovations, we strongly recommend spray foam due to probable cracks and fissures on the walls or foundation related to the deterioration of the structure over time.
