Single Hung Windows in Ottawa
A single hung window has two sashes stacked one above the other. The top one stays put; the bottom one slides up to open and tilts in when you want to wash the outside. It’s the classic up-and-down window found on older houses, and it’s the way to replace tired wood or aluminium sash windows without changing how the front of the house looks.

Matching the Look of Your House
Keep the proportions. Hung windows are taller than they are wide, with a horizontal rail across the middle. Replacing them with sliders turns that tall shape on its side; replacing them with single-hung keeps it.
Grilles that suit the age of the house. Colonial grilles across both sashes for a Georgian or colonial front; top-sash-only grilles for a craftsman or 1920s look; or none for a clean modern line.
Colour on the outside only. On an older house, a painted exterior that matches the trim, with white inside, often suits best. Our painted finishes are covered for 10 years.
Three Places Hung Windows Don’t Suit
- Over a kitchen counter or a deep sill. Lifting a sash while leaning across a counter is awkward. A casement with a crank is easier.
- Second-floor rooms where you can’t reach outside. The top sash of a single-hung doesn’t tilt, so its outside face needs a ladder. Choose double-hung instead: both sashes tilt in.
- Small bedroom windows. Only the lower half opens, so a hung window has to be tall to give the 0.35 m² egress opening a bedroom needs.
What the Tests Show
Our single-hung window was tested to CSA A440.2:
- Energy Rating 34 with standard double glazing, which meets ENERGY STAR
- 36 with the i89 room-side coating, 39 with triple pane
- Air leakage 0.6 L/s·m², close to our sliders; a crank-out casement seals tighter
