When it comes to improving your home's efficiency, you probably think of retrofitting the most visible places first. However, what many people overlook is the attic — which is out of view but is actually the most important place to have proper insulation.
It's more than adding good insulation that will make your home feel more comfortable. Air sealing is the first step, and a vital component of the weatherization process to make your attic airtight, greatly limiting airflow from the outside to the inside and vice versa.
The combination of air sealing and adding the best insulation — namely, spray foam combined with blown-in cellulose or blown-in fibreglass — will help create an effective air and vapour barrier. Spray foam blankets the entire attic floor as well as support beams, plumbing and electrical components while delivering a higher R-value (the industry standard for thermal resistance) than other types of insulation.
This means valuable heat won't be escaping from your home, which will have a positive impact on your family's comfort and your utility bills. Spray foam insulation is not the least expensive insulator on the market, but the investment will pay for itself over the course of a few seasons. In fact, there's a handy online energy audit tool called My EnergyXpert that can estimate how much money you can save with a home retrofit.
Adding the right insulation for your home and air sealing are two steps towards attaining a better indoor environment, but it's also important to do your research and make sure you choose a contractor that will do the job right the first time — and that includes removing the existing, less-efficient insulation.
Having a properly insulated attic can also help your new roof shingles last longer, because it will reduce the moisture that can lead to damage. If you're planning on getting a new roof, have the attic looked at first.
