Why Insulate With Spray Foam?

Save Money

Living in a home that isn’t properly insulated is like throwing money out the window. Air leaks in and out through cracks and openings in your home’s structure.

Protect your family

SPFI eliminates drafts and cold spots, keeping room temperatures constant and comfortable. Its air-tight vapour barrier keeps moisture, mould and mildew from entering your home.

Environmentally Friendly

We now have an option to install eco-friendly spray foam insulation. It is a high quality, premium product ideal for residential, commercial, and industrial installs.

seals clean air in

Spray foam insulation expands to fill all gaps and becomes rigid when dried. It greatly reduces the amount of dust, pollen and pollutants from entering your home. Spray foam insulation works as a barrier, keeping outside noise, insects and rodents.

most efficient

Spray foam has the highest R-Value of any insulation – because your furnace and air conditioner don’t have to work so hard, they’ll cost less to operate and last years longer.


Say goodbye to drafts, or hot and cold spots. Air leaks in and out through cracks and openings in your home’s structure. Spray foam insulation stops this wasteful air exchange.

Still Not Sold on SPFI?

Spray foam insulation is truly multi-purpose – it seals airtight; provides very high R-Value; deters mold; and adds structural strength where installed. For homeowners who are focused on improving home energy efficiency, spray foam insulation is the best option, and with long-term energy savings.

Spray foam insulation, once sprayed, expands and completely seals the area being insulated. This air-tight seal is more energy efficient due to less air leaving your home. Your home stays warm in winter and cool in the summer while you save up to 50% on your energy costs.
