R-Value + Air Barrier = Quality Insulating Value
What do you see, when you walk thru new homes. We see engineered hardwood floors, big trims around doors and windows. Granite or granite like counter tops. Popular today are the stainless steel appliances and appliances which beeps and tweets. So much has improved in our homes in the last thirty years, except for the insulating of our homes.
The cost of heating our homes through the winter, and keeping our homes cooler during the summer depends on what the envelope of your home is built with. A quality insulation has to have two very important property. The ability to reduce heat transfer, and the ability to reduce air infiltration.
Our current insulation of choice is batt insulation, which relies on entrapped air to insulate your home. Thus –20C climate outside is infiltrating in your wall cavity to steal more heat energy out of your house. The Batt insulation has no air barrier qualities, and relying on the vapour barrier to act as an air barrier as well.
Polyurethane spray foam insulation has the ability to reduce heat transfer and reduce air infiltration with one application. Spray foam expands initially to fill in all the cavity, without joints, the general structure of the product makes it airtight, with great total insulating qualities.
