Triple glazing can provide added insulation, but it is not always necessary for every window, especially when the main goal is summer comfort. In many cases, choosing the right double-glazed Low-E package can provide strong performance while keeping windows easier to use and service.

This matters for sliders, hung windows, patio doors, very large windows, and windows installed high above the floor. Triple glazing adds extra weight, which can make some windows and doors harder to operate. For summer heat control, the right Low-E coating can often be more important than simply adding more glass.

For Ontario homeowners, energy efficiency is a major motivation to upgrade windows – especially given our freezing winters and hot, humid summers. If you feel cold drafts around your old windows in winter or notice rooms overheating in the summer, those windows are likely leaking air and forcing your furnace or air conditioner to work overtime. Modern energy-efficient replacement windows are designed with insulated frames, Low-E glass coatings, and tight seals to eliminate drafts and help maintain a consistent indoor temperature.

In fact, replacing old single-pane units has been proven to improve a home’s ability to retain heat during frigid winter months by as much as 50%. Similarly, high-performance windows can reduce the sun’s unwanted solar heat gain in your house to as low as 14%, for magnificent comfort year round, energy savings and lower environmental impact for many years to come. These upgrades mean you’ll stay more comfortable year-round while spending far less on heating and cooling. Additionally, using less energy not only lowers your utility bills but also reduces strain on the environment by conserving natural resources. As an added bonus, the same features that seal out the weather – multiple panes of glass, inert gas fills, and quality weatherstripping – also help block outside noise, giving you a quieter and more peaceful home interior.
