Why Invest in Your Home’s Energy Efficiency?

Today 17% of all energy used in Canada goes towards running our homes.
This generates 15% of the country’s greenhouse gas emissions, which makes your home a great place to start in reducing your ecological footprint.

Not only does improving your home’s building envelope and increasing your home’s insulation help the environment, it helps your wallet too.
