Most homeowners are aware that warm air rises and attic insulation is important for reducing heating costs. They are also aware that over the years the building code has changed significantly, insulation materials have improved as has knowledge of the importance of air and vapour barriers. Chances are you are reading this because your attic doesn’t have as much insulation as you would like and you heard that doubling the amount of insulation in your attic can effectively halve the heat loss.
If you have existing insulation in your attic chances are blown in insulation is a cost effective way to increase the R-value (insulation value) and reduce your heating and cooling bills. Homes fitted with Batt insulation in the attic (pink rolls) or loose fill fiberglass are ideal candidates for adding blown in fiberglass.
At Eco Energy, we ensure the use of leading products in the industry such as Owen’s Corning Pro Pink blown in fiberglass, CertainTeed Insulsafe blown in fiberglass and Thermo Cell Thermo Shield Blown in Cellulose.
New homes, garages or additions have the luxury of opting for spray foam insulation, which additionally provides an air and vapour barrier reducing air infiltration, and is a much more effective, though slightly more expensive up front cost. Or the popular hybrid approach of applying 2″ (R13) of spray foam, which we top up with sufficient blown in insulation to achieve a combined value of R50, taking advantage of the superior insulation properties of SPF and the lower cost per inch of blown insulation.

For mature homes, with some existing insulation (except vermiculite), adding additional attic insulation such as blown in insulation is a more cost effective solution. It is recommended that we inspect and assess the air barrier and insulation to provide the best advice and explain the trade offs of the various options available to you.
