Who Are the Best Manufacturers of Spray Foam Insulations?

Having the right kind of insulation in your home can save energy costs and reduce your overall carbon footprint.

In Canada, you’ll find different kinds of insulation foams available on the market. By choosing the best one, you will get the best value for your hard-earned money.

What is This Spray Foam Insulation?

Also called foam insulation, spray foam is a new technique to insulate your home. It will prevent any air leaks throughout your house. It is of polyurethane foam, just like the one present in your memory foam mattress and couch.

Spray foam can ensure quality thermal insulation as it has a high R-value. R-value is the measurement of the density of this foam and how well it insulates. You will spray this foam into your walls and ceilings, and it will expand.

With the expansion, it will form an airtight seal. Spray foams with a high R-value can also be moisture-tight. So, your home will become impenetrable for any of those external elements.

Where Can I Use It & How Long Does It Last?

You can use this spray foam throughout your house. This includes your roof, your walls, your attic, and various other foundations.

But different areas throughout your house will need a different type of spray insulation density. We will talk about it briefly in just a bit.

Proper application of this spray foam will last till the lifetime of the house. However, open-cell spray foam is not moisture-proof, so that it will deteriorate over time.

But this is not the case with the closed-cell spray foam. It is air and moisture-proof, and it will stand the test of time. This is why it is more expensive than its open-cell counterpart.

Types of Foam Insulation

Primarily there are two types of spray foam insulations.


This foam insulation is much denser and is more expensive, with R-value ranging between 6 to 7 per square inch. However, it prevents air leaks and is moisture-tight too.


This is a less dense type of insulation foam, and its R-value is around 4 per square inch. It prevents air leaks but is not effective against moisture.

Other types

Other types include aerosol cans featuring 1-part formulas, which are suitable for DIY projects for your doorways. There are low-pressure sprayers also available with 2-part formulas, and they are suitable for smaller projects.

You can find 2-part kits that are applied with high-pressure sprayers. These are suitable for large-scale projects.
