When Twin Cities homeowners start a window replacement project, the style decision usually comes down to two finalists: casement (crank-out) or double-hung (slide-up). Both are available from every major brand we install, both come in the same materials and glass packages, and both can look right on almost any house.
But they behave differently — in how they seal against a January wind, how you clean them, and where they physically fit. Here's the honest comparison we walk through at kitchen tables every week.
How each style works
A casement window is hinged on one side and cranks outward like a door. When it closes, the locking hardware pulls the entire sash tight against compression weatherstripping on all four sides.
A double-hung window has two sashes that slide vertically past each other. Both sashes typically tilt inward for cleaning, and you can ventilate from the top, the bottom, or both.
Side by side: the decision table
Here's how the two styles compare on the factors that matter most in our climate:
| Factor | Casement | Double-hung |
|---|---|---|
| Air sealing | Excellent — sash compresses into the seal; wind makes it tighter | Good — sliding sashes need some clearance, so slightly more air movement |
| Ventilation | Catches breezes like a sail; full opening ventilates | Top/bottom options; about half the opening ventilates |
| Cleaning | Crank open and reach both sides from inside (most sizes) | Both sashes tilt in — easiest of any style |
| Egress fit | Meets bedroom egress in smaller openings since the full width opens | Needs a larger opening to meet egress clear-space rules |
| Obstructions | Swings outward — avoid over decks, walkways, patios | Never protrudes — safe everywhere |
| Hardware | Crank and multi-point locks — more moving parts | Simple locks and balances — less to maintain |
| Typical cost | 10–20% more than double-hung | The value benchmark for replacement windows |
Where casements win in a Minnesota home
The compression seal is the headline. On a windy site — open lots, lake exposure, the west wall of a two-story — casements measurably out-seal sliding styles, and that shows up in comfort during a windchill week.
They're also the practical answer for hard-to-reach openings: over the kitchen sink, behind a bathtub, anywhere you'd struggle to push a sash up. A fold-away crank handle takes little effort even at full arm's reach. And in basements and smaller bedroom openings, a casement is often the easiest way to meet egress requirements, since the entire sash swings clear.
Where double-hungs win
Double-hungs are the traditional look — on a 1920s St. Paul four-square or a classic Minneapolis bungalow, they simply look correct, especially with grille patterns that match the era.
They're also the right call anywhere an outward-swinging sash would be in the way: along decks, patios, sidewalks, and play areas. Cleaning is their other superpower — both sashes tilt into the room, which second-story owners appreciate every spring.
The mix-and-match answer most homes land on
This isn't an all-or-nothing decision. A typical whole-home project we install might use casements in the kitchen and primary bedroom, double-hungs across the street-facing front for curb appeal, and an awning or two in the basement. Brands offer both styles in the same series, so colors, hardware finishes, and glass match across the whole house.
If you're weighing styles for a replacement project anywhere in the Twin Cities metro, we'll bring samples of both to your free in-home estimate so you can crank, slide, and tilt them yourself. Call 763-204-2099 to schedule.
Frequently asked questions
Which is more energy efficient, casement or double-hung?
With the same glass package, casements typically test slightly better on air infiltration because the sash compresses into its weatherstripping rather than sliding past it. Both styles from a quality manufacturer will be dramatically tighter than the worn windows you're replacing.
Do casement window cranks wear out?
Crank operators are a wear item over decades, but on quality brands they're metal-geared and replaceable. Keeping the hinge track clean and avoiding forcing a sash against a locked position are the two habits that extend their life.
Can I replace double-hung windows with casements?
Usually, yes — the rough opening doesn't care which style fills it. The main checks are exterior clearance (nothing blocking the outward swing) and proportions, since very wide openings may need paired casements or a casement-picture-casement combination.
Which style is better for bedroom egress in Minnesota?
Casements generally meet egress requirements in smaller openings because the full sash swings clear of the opening. If you're replacing bedroom windows in an older home, this is worth checking before you fall in love with a style — we verify egress compliance as part of every measure.
