How Changes To The Ontario Building Code Impact Window Installation And Renovation
As of January 1, 2017, a new window building code brings significant changes to window installations and renovations in Ontario. More insulation, improvements to the efficiency of furnaces and hot water tanks as well as ‘better windows’ are expected to increase the energy efficiency of new homes and cottages by 15% and large buildings by 13%. The Ontario Ministry of Municipal Affairs and Housing estimates that the new standards will make houses built this year 50% more energy efficient than a home constructed in 2005. For renovations, the code changes only affect any additions that you might make to your cottage or home.
Why the emphasis on windows? According to Natural Resources Canada, windows can account for up to 25% of the total heat loss in a home, with air entering through cracks and crevices around them driving up your energy consumption. Energy-efficient windows provide better insulation, reducing heat loss or gain and lowering your energy bills.
If you require new windows and installation, or are planning an addition to your cottage, familiarise yourself with the window building code changes. Our experts have provided an overview of some important amendments below.
Important changes in door and window building code
- Basement windows do not need to be rated
- West and east-facing windows can have lower ratings which allows for the remaining to have a higher rating.
- One exterior door does not have to meet the minimum rating
- Door leading from a non-heated space to a heated space (or vice versa) must have an insulated core with a weather strip.
- Windows and doors have two ways to qualify for energy efficiency, using either the ER (higher # is better) and/or U value (lower number is better)
- Do not remove labels until after inspection
- Window area rules
- Includes skylights
- Measure at RSO (rough opening for a window or door)
Note: Zone 1 includes most of Southern Ontario while Zone 2 covers the area north of Huntsville.
