Window types for Calgary homes: which one belongs in which room

Why the way a window opens matters more than the brand

Two windows with the same glass can lose very different amounts of heat, and the reason is almost always the sash, not the pane. A sash that slides has to clear its track, so it can only touch a soft brush or felt strip. A sash that swings or tilts shut can be pulled hard against a rubber gasket by its lock, the way a fridge door seals. In a Calgary January, with a chinook swinging the temperature 20 degrees in an afternoon, that difference is what you feel standing next to the window — and what you see on the gas bill.

So the first question is not «vinyl or fiberglass» or «double or triple pane». It is: does this window compress a gasket when it locks, or slide past a strip? Everything below follows from that.

The six types at a glance

«Cost order» is relative, because every quote depends on size, glass and how the window is installed. For the one type I sell, the installed price per opening is published on the cost page — $1,800 to $7,500 depending on the REHAU line, wall finish and shape.

Casement (crank) windows

The default window in most Calgary houses built after about 1980. A crank swings the sash outward on side hinges, and the lock pulls it back into a gasket. Sealed well, a casement is a good cold-climate window — which is why I will tell you to keep yours if the frame is sound and the hardware still pulls tight. The weak points show up with age: the crank gear strips, the hinge arm sags so the sash no longer meets the gasket evenly, and the screen sits on the inside where it collects condensation. In wind, an open casement is a sail; many homeowners stop opening the big ones. The full comparison is on casement vs tilt-and-turn in Calgary.

Casement wins when: the existing units are sound and you only need glass or hardware; the opening is small; the room has no inward swing room (a sash that opens into the room needs the blinds and the plants out of the way).
Look at tilt-and-turn instead when: the crank or hinge has failed on more than one window, the opening is large, the room is a bedroom you want to air at night without a sash hanging outside, or you cannot reach the outside of the glass to clean it. Full comparison: European vs North American windows.

Slider windows

The least expensive operable window and, for some openings, the right one. A slider has no sash swinging in or out, so it suits a low, wide opening above a counter, a window behind a deck railing, or a basement where egress hardware has to be simple. The trade is the seal: the moving sash rides a track and touches a brush strip, which is why sliders are the window people stand near and say «I can feel the cold». The second sash also has to fit in the same depth, so the glass units in a slider are usually thinner than in a casement of the same price.

Slider wins when: budget is the deciding factor, the opening is low and wide, or the window is in a garage, shed or unheated space.
Not the answer when: the room is a bedroom on a street, you are paying for triple glazing (a thin, leaky frame wastes the glass), or you are tired of drafts — a slider cannot be adjusted tighter; a compression window can.

Awning windows

A casement turned on its side: hinged at the top, cranked out from the bottom. Rain runs off the open sash, so an awning can stay open in a shower — useful over a bathtub or a kitchen sink. It seals the same way a casement does. Limits: the opening is small, the screen is inside, and the gasket at the bottom edge sits where snow and ice collect on the sill.

Awning wins when: you need ventilation from a small, high opening and nothing else.
Tilt-and-turn covers the same job: the tilt position opens the top of the sash about 10–15 cm for ventilation in any weather, with the screen outside and the handle at hand height, and the turn position lets you clean the glass. Details on the screens and child-safety page.

Picture (fixed) windows

No sash, no hardware, no air leak path — a fixed unit is the best-insulating window you can buy for the money, which is why a living-room wall of glass is usually mostly fixed. The question is how much of the wall you can afford not to open. Building code requires an operable, large-enough window in every bedroom (see the permit page for egress), and a kitchen or bathroom without a vent window is a condensation problem waiting to happen.

Picture wins when: the view is the point and the room has another way to vent.
The combination that works in Calgary: a fixed centre unit with one operable tilt-and-turn beside it — one sash to maintain, the rest glass. Every REHAU line I sell is available as a fixed unit in the same frame depth, so the sightlines match.

Single- and double-hung windows

Common in older Eastern Canadian and American houses, rare in Calgary new builds. The sash slides vertically against brush strips, so they share the slider's weakness, and the meeting rail in the middle is an extra leak line. Most Calgary installers stopped offering them except for heritage replacements where the look must match. If you have hung windows and like them, the honest advice is that a modern casement or tilt-and-turn in the same opening will be noticeably warmer, and the frame proportions can be matched closely enough that the house still reads as itself.

Tilt-and-turn windows

The European standard and the one type I sell, so judge this paragraph accordingly. One handle gives two positions: turn it 90° and the top of the sash tilts into the room for ventilation; turn it 180° and the whole sash swings inward like a door. Locked, a multi-point mechanism pulls the sash into a gasket on every side at once. The frames are uPVC with a steel core, which is what lets the sash be large without sagging. Screens sit outside, so the sash never touches them. Full product page with prices and warranty: tilt-and-turn windows in Calgary.

Where it does not win: a window the sash would hit (deep sills full of plants, inside shutters, a toilet directly under a small window); openings so small that a casement is cheaper and does the job; and budgets where a slider is the only way the whole house gets done this year — in which case I would rather see you do one room properly than every room with the wrong window.

Choosing by room, not by catalogue

This is how I walk a house on a measurement visit:

Bedrooms — must open for egress, should vent at night quietly and safely: tilt-and-turn or casement; never a picture window alone.
Living room — mostly fixed glass for insulation and view, one operable unit for airflow.
Kitchen over the sink — awning or tilt-and-turn with the handle you can reach; a crank behind a tap is a daily annoyance.
Bathroom — a small operable unit you can leave open in rain: awning or tilt mode.
Basement — egress size first, then whatever seals; sliders are common here because of cost, but a basement bedroom on the north side is exactly where a compression seal pays back.
Street-facing rooms — the seal also decides noise; see windows that reduce traffic noise.

Before you pick a type, check whether you need new windows at all

Fogged glass, a stripped crank or condensation on the inside face of the pane each has a cheaper fix than replacement. I keep a six-step check you can run yourself, and about a third of the homes I visit leave with «not yet» from me. When the answer is yes, the next decisions are glass (double or triple pane), installation method (insert or full-frame) and whether to do the house in one go or one room at a time.

Who I am and what I sell

I am Lex Oleksiienko, a window specialist at Permanent Windows Solutions in Calgary. PWS supplies and installs REHAU tilt-and-turn and fixed uPVC windows and European doors; I advise, measure and quote, and I earn commission when you buy. I do not sell casements, sliders or hung windows, which is exactly why I can tell you when one of those is the right answer — nothing in it for me either way.
