What this means in Canada

Cold weather makes interior glass temperature matter more

As outdoor temperatures drop, the interior glass surface tends to feel colder. Better glazing usually means warmer interior glass, better comfort near the window, and less chance of interior condensation when humidity is high.

Single pane: weakest thermal barrier
Double pane: practical Canadian minimum
Triple pane: strongest comfort upgrade
Humidity makes poor windows show problems faster

Best fit by situation

Single pane
Mostly legacy stock or sheds. Not ideal for modern Canadian comfort or efficiency goals.
Double pane
Good mainstream choice for many Ottawa homes, especially with quality low-e coatings and gas fills.
Triple pane
Best where winter comfort, condensation resistance, and energy performance matter most.
