Guide to Commercial Building Insulation Options

Did you know that space heating accounts for 55% of the energy used in commercial buildings in Canada?

That's more than half of your business's energy bills! 

Keeping that heat inside your commercial building should be a priority. It's expensive enough running a business – don't waste money and precious energy by allowing that heat to escape. 

Commercial building insulation is the ultimate way to keep that valuable heat inside your commercial building. For great energy efficiency, you need to look for a high R-value. This is a measure of how easily air and water can penetrate the surface.

Read on to find out what kinds of commercial insulation are available and which ones are right for you.


Spray Foam Insulation

Spray polyurethane foam (SPF) is a plastic solution that is applied with a compressed air spraying machine. Choose from open-cell (R-value 3.6 per inch) or closed-cell foam (R-value 6 per inch) depending on your needs.


Spray foam has a high R-value. It is water-resistant and completely airtight and fairly easy to have installed. You can save money in the long run with this high-performance insulation that will last a lifetime.


Spray foam insulation is very popular because of its flexibility. It can be applied almost anywhere and expands to fit perfectly into nooks and cracks. Use it to seal off old vents, electric and plumbing pipes, any space or gap you see in your walls or roof.

Fibreglass Batt Insulation

One of many forms of fibreglass insulation is batt fiberglass. A popular choice made from sand and recycled glass, this is often a more eco-friendly option. The fibreglass is provided in easy-to-manage format for simple installation.


The batts make it easy to cut to the required size. The sand and glass material makes it naturally fire retardant which makes it favoured by insurers. Fibreglass is also a great sound insulator. It has an R-value of 3.8 per inch.


Batt fibreglass is mostly popular for use in wall cavities and ceilings for insulating, and floor to floor cavities for sound dampening. It creates an insulated barrier at the top of the building minimizing heat loss through the roof and the walls.

Loose-Fill Insulation

This insulation method fills areas with loose materials such as fibres, foams, cellulose, and mineral wool. The particles are blown into a space using an insulation blower. This insulation has a typical R-value of 2.7 to 3.6 per inch.


The loose materials can conform to any space creating a thick layer of heat rapping, soundproofing insulation.


Very versatile and can be used almost anywhere from floors to walls to ceilings and roof spaces. It just needs a cavity to settle in such as a stud wall.
