The Secret to Saving Money with Improved Home Insulation in Toronto

August 26, 2017

For homeowners ready to improve their home insulation in Toronto, there’s no project that can deliver a better return-on-investment. Sometimes, with remodeling and renovating, it's easy to overlook improvements to the home’s energy efficiency, particularly home insulation. Needless to say, home insulation isn't very glitzy, and it’s certainly not a “fun” project, like a kitchen reno.

secret to saving money with home insulation in torontoToday, home energy efficiency is a high priority, and home insulation is at the top of the upgrade list. By any measure, industry experts estimate that upgraded home insulation and air sealing can save upwards of 20% on annual utility costs. As such, making improvements to home insulation in Toronto represents a very substantial ROI that will actually pay for itself season after season.

What’s important with insulation is to target the most vulnerable areas of the home, and boost areas of poor performance. While many think that more insulation is better, the important thing is to actually consider overall performance. With professionals like Great Northern Insulation, upgrades to energy efficiency are specifically targeted so that the best overall ROI is achieved.

In general, most homes in Canada are under-insulated. It means that the cost of winter heating and summer cooling is significantly higher than it should be. For homeowners who are interested in retrofitting their home insulation in Toronto, the options are varied, although some parts of the house will deliver more measurable results (a professional approach is recommended).

The Basement

In the basement it’s absolutely essential to ensure that the foundation, walls, and crawl spaces are properly sealed and insulated. High performance basement insulation will prevent heat loss, protect the foundation, stop moisture build up, and provide energy efficiency, with reduced utility bills. With a professional installation, the cost of the project will pay for itself in a few short years.

The Ductwork

For the ultimate in energy efficiency, heating/cooling ducts should be properly sealed and well insulated. This will allow for optimum airflow, regardless of the season, and ensure that there is minimal air leakage throughout the house. A professional Energy Auditor can ascertain the long-term benefits, and the cost benefit of such a project. Utility savings could be substantial.

Exterior Walls

Homeowners who are renovating can take the opportunity to better insulate exterior walls. With Great Northern Insulation, one option is to install spray foam into the open walls and re-drywall. Another option is to “inject” loose-fill cellulose into existing wall cavities, without disturbing the drywall. Either way, the dead air space is filled and R-Values are boosted considerably.

The Attic

Attic insulation is likely the most constructive insulation upgrade that any homeowner can make. A well-insulated attic stops warm air from escaping in winter and prevents outdoor heat from intruding in the summer. Here, high performance insulation and effective air sealing will improve energy efficiency dramatically, reduce energy consumption annually, and create more comfort.
