Advantages of Spray Foam

Spray Foam Insulation in Toronto and the GTA

Spray foam is a distinctive insulation and sealing solution, molding itself to the application surface. This on-site application process creates a robust building envelope, enhancing overall energy efficiency.

In a rapid reaction, distinctive liquid components combine to create insulating foam sealants and spray foam insulation. Once mixed, the result quickly transforms into foam that can seal off gaps, create a barrier against air, moisture, and vapour, and extend protection. The flexibility of this product makes it ideal for covering interior and exterior walls, attics, crawlspaces, and small openings. The ability to cut down on air infiltration and contaminants contributes to overall comfort and energy savings for homeowners.

Advantages are distinct for each type of spray foam and its application method. The three major types are:


  • 3 lbs./cubic ft., closed-cell foam
  • R-Values starting at 5.5 per inch*
  • Ideal for exterior and roofing applications


  • 2 lbs./cubic ft., closed-cell foam
  • R-Values starting at 5.7 per inch*
  • Commonly used for continuous insulation, interior wall cavity fill, and unvented attic applications.


  • 0.5 lbs./cubic ft., open-cell foam
  • R-Values starting at 3.6 per inch*
  • Frequently used for interior wall cavity fill and unvented attic applications.

(*R means resistance to heat flow. The higher the R-value, the greater the insulating power. Refer to the seller’s fact sheet on R-value for more information.)

High-density Spf Advantages

Density has much to do with SPF effectiveness, as a higher density will provide better protection against the sun. The benefits of high-density SPF are immense, as it shields your skin from the harmful effects of UV radiation. You will also be protected from prolonged sun exposure’s wrinkles and fine lines. Another advantage of high-density SPF is that it doesn’t need to be reapplied as frequently. This means you can enjoy your time outside without worrying about getting burnt. Overall, high-density SPF is an excellent way to keep your skin youthful and healthy.

Builders sometimes use high-density spray foam for maximum insulation and durability during construction. This more concentrated foam creates a smooth and seamless unity when used as roofing or exterior insulation. This foam type minimizes energy expenses over an entire roofing system’s lifespan and offers thermal-resistant features. Protecting against water and wind infiltration, high-density spray foam strengthens stability and safeguards the structure. Increased bonding also raises defences against wind uplift, further minimizing damage during heavy storm periods.

Medium-density Spf Advantages

A versatile choice, medium-density foam presents climate and building-specific advantages when applied via high or low-pressure two-component spray. This closed-cell spray foam offers optimal insulation per inch with its commendable R-value. It acts as an air, vapour, and water barrier and is renowned for its noise-reducing properties. Medium-density foam’s high tensile and bond strength remain unaffected by moisture.

Low-density Spf Advantages

Low-density spray foam, or open-cell foam, gives continuous insulation and an air-sealing barrier. Its open-cell structure makes it soft and flexible because of its weight, which is almost 0.5 lbs. per cubic foot. While used in different applications such as walls, unvented attics, ducts, ceilings, vented attics and crawl spaces, it serves as an air barrier but at the same time remains vapour and moisture permeable as well for low-density foams. It can be used for sound absorption because of its large cell structure and softer texture, making it versatile.
