Importance of Insulated Windows and Doors -Toronto

At Toronto, our products are designed to be as functional and useful as they are beautiful. We create each of our windows and doors with superior insulation to ensure your home is guarded against the outdoor elements while also giving you these benefits:

Cost Savings

It’s just a small draft, how much harm can it do, right? While drafty windows and doors may just seem like an inconvenience, they could be costing you hundreds more in energy bills each year. While it may seem expensive to replace your windows and doors Toronto residents stand to recoup those costs and then some with properly insulated replacements.


Additionally, your home will be more comfortable with proper insulation.. Oftentimes, no matter how much you turn up the heat or AC to compensate for drafts, you simply can’t eliminate the discomfort caused by frigid or humid air leaking in from the outside. If you’ve ever spent a night tossing and turning because you couldn’t stop sweating or couldn’t get warm enough, then you know the importance of proper insulation.


If you’ve opted to use a space heater to minimize the chill from drafty windows and doors, you could be putting yourself at higher risk for a home accident. Space heaters, though improved over the years, are still responsible for thousands of fires and hundreds of deaths each year. Moreover, space heaters tend to eat up nearly as much energy as turning up the heat in your home, so there isn’t a great cost savings either.
