Replacement Windows in Ontario
Choose the view, ventilation and finish that make your home feel right.
Made for the way you live
Start with the room. Find the right window.
Replacing windows is a chance to solve everyday problems: a room that feels cold, a sash that is difficult to open or a view interrupted by the wrong layout. Start with the purpose of each opening, then compare the styles below. Casement and awning windows open outward; sliders and hung windows operate within the frame; picture and shaped units can bring a different emphasis to the façade.
The glass package, frame and installation work together. Review double and triple pane options, Low-E coatings and complete-window ratings alongside your room’s sun exposure. Exterior colour, interior trim and privacy glass should be part of the same decision, so the result works from both sides of the opening.
For a useful replacement-window quote, share photographs, the number of openings and the issues you want to address. Ask whether the existing frame is suitable for a retrofit or whether fuller removal and repairs are needed. GreenOn Homes serves the GTA and selected Southern Ontario communities from Concord, with its own manufacturing and employee installers.

- 01Sealed glass panesSeparated glass panes form an insulating sealed unit. Confirm the glazing configuration for your chosen window.
- 02Low-E coatingA low-emissivity coating reduces radiant heat transfer through the glass, helping control heat loss and solar gain.
- 03Super Spacer® warm edgeA foam-like spacer between the panes that resists transferring temperature from glass to glass, helping reduce condensation around the edge of the window.
- 04Argon fillAn insulating gas such as argon can reduce heat transfer between the panes. Ask which fill is included in your selected unit.
- 05uPVC frameA multi-chambered uPVC frame, fusion-welded at the corners for an airtight, watertight seal.
