Windows have a considerable impact on thermal insulation and the comfort of the indoor environment. They are critical to maintaining a steady temperature and good lighting. With significant advances in window technology and construction, upgrading windows to Power Smart standards serves to improve the performance of a building by reducing heating and cooling costs and improving the overall comfort.
High performance windows have some or all of these energy efficient features:
- vinyl, fibreglass or wood frames;
- triple glazing;
- insulating spacer bars;
- low emissivity (low-e) coatings on the glass;
- argon, rather than air, between the panes.
