Casement vs. Double-Hung Windows: Which Works Best in a Minnesota Winter?

Picking new windows means picking a style. For a lot of Central Minnesota homes, it comes down to two: casement or double-hung. Both are good windows. They just work differently. Those differences show up most in a Minnesota winter, when the wind is blowing and the glass is cold. That's when you least want a window that sticks or leaks.

This guide compares casement vs. double-hung windows on the things that matter here in St. Cloud and the surrounding area: how each one seals against the wind, how it handles screens, cleaning and ice, and which rooms each style suits best.

How Casement and Double-Hung Windows Work

A casement window is hinged on one side and swings outward, like a door. You open and close it by turning a crank at the bottom of the frame. When you lock it, the sash (the part that holds the glass) is pulled tight against the frame.

A double-hung window has two sashes, one above the other. Both slide up and down in tracks along the sides of the frame. A single-hung window looks the same, but only the bottom sash moves. Many double-hungs made today also let each sash tilt inward, so you can clean the outside of the glass from inside the house.

Here's how the two compare at a glance:

Sealing Against Minnesota Wind: Casement vs. Double-Hung

Wind is what finds the gaps in a window. The biggest difference between these two styles is how they close.

A casement closes a lot like a freezer door. The crank and lock pull the sash straight into the weatherstrip and squeeze it shut. When wind blows against that side of the house, it presses the sash even tighter into the frame. As we put it on our window and door replacement page, casement and awning windows "crank open outward, creating a tight seal when closed."

A double-hung has to slide, so the weatherstrip along its sides can't be squeezed as hard. It has to let the sash move. There's also a seam in the middle, where the rails of the two sashes meet (these are called the meeting rails). That gives cold air a few more places to try to sneak through. A well-built double-hung makes up for a lot of this with extra weatherstripping and an interlock where the sashes meet. Vector, for example, lists a triple weatherseal and an interlock weatherstrip on its Envision double-hung.

You can see the style difference in Vector's own test results. In its 2025 product brochure, the Envision casement earned a lower air-leakage rating than the Envision double-hung. Same maker, same product line, and the casement still rated tighter.

So is a casement the automatic winner? Not always. A good double-hung that's installed right can still seal well. Our window and door page notes that double-hungs "seal tightly against cold air infiltration in winter." On the other hand, a casement with a worn crank or tired weatherstrip won't seal the way it did when it was new. Build quality and a careful install matter a lot with either style.

One more thing: style mostly affects air leaks. How much heat gets through the glass itself depends on the glass you pick, like double- or triple-pane glass. You can get the same glass options in either style. To learn what the energy numbers on a window label mean, read Can New Windows Really Lower My Bills?

Winter tip: Lock your windows, whatever style they are. The lock does more than keep people out. On a double-hung, it pulls the two sashes together at the meeting rails. On a casement, it pulls the sash tight against the weatherstrip. An unlocked window can leak cold air even when it looks closed.

Ventilation, Screens and Cleaning From Inside

Ventilation

A casement opens nearly all the way, so you get fresh air through almost the whole window. Because the open sash sticks out from the wall, it can also catch a breeze moving along the side of the house and steer it inside. On a gusty day, though, don't leave a casement cranked wide open. A strong gust can push on the open sash and strain the hinges and crank.

A double-hung only opens about halfway, since one sash slides over the other. But you can open it at the top, the bottom or both. Warm air tends to leave through the top while cooler air comes in at the bottom. Double-hungs are also the style that holds a standard window air conditioner. If you run a window AC in the summer, keep a double-hung in that room. Sliders and casements need a special air conditioner made for them.

Screens

Because a casement swings out, its screen goes on the inside. That makes the screen easy to pop out and clean from inside the house. The trade-off: while the screen is in, you look through it even when the window is closed.

A double-hung's screen goes on the outside. A half screen covers only the bottom half, so the top half of your view stays clear. A full screen covers the whole window, so you can open either sash and still keep the bugs out. Vector lists a full screen on its Envision double-hung.

Cleaning

Both styles can usually be cleaned from inside. That matters on second-floor windows, and during our long winters, when getting to the outside of the glass isn't easy. On a double-hung, you tilt each sash in and wipe the outside of the glass from the room. On a casement, you crank the sash wide open and reach through the gap on the hinge side. Vector puts what it calls a "washability hinge" on its Envision casement for this, according to its product brochure. Not every casement opens that wide, so if you plan to clean from inside, check the window before you buy.

Cold-Weather Operation: Cranks, Sashes and Ice

Most of us keep our windows shut for most of the winter. Even so, cold weather is hard on window hardware, and each style has its own weak spots.

Casement cranks

A casement's crank turns a small set of gears that push the sash open. If frost or ice has frozen the sash to the weatherstrip, cranking harder can strip those gears or bend the arm. If it won't budge, stop. Let the sun or the heat in the house thaw it, then try again. Check outside, too: snow or ice piled on the sill can keep the sash from swinging out.

The good news is that the crank is a replaceable part. A crank that's stiff, slips or spins freely doesn't always mean the whole window is done.

Double-hung sashes

A double-hung can freeze too, usually where the bottom sash sits on the sill or where the two sashes meet. Don't pry it loose with a knife or screwdriver. That can tear the weatherstrip and let in even more cold air. Wait for it to thaw.

Double-hungs also rely on balances, the parts hidden in the sides of the frame that hold a sash in place when you open it. When balances wear out, a sash may slide down on its own or refuse to stay open. That's a common sign of an aging double-hung.

Where Each Style Fits: Kitchens, Bedrooms, Basements and Older Homes

You don't have to pick one style for the whole house. Plenty of homes use both. Here's where each one tends to work best.

• Over the kitchen sink: casement. Reaching across a counter to lift a double-hung sash is awkward. A casement or awning window cranks open with one hand, which is why we suggest them for hard-to-reach spots like above a kitchen sink.
• Bedrooms: either, but think about the opening. Every bedroom needs a safe way out in an emergency, and that's often a window. A casement opens nearly all the way, while a double-hung opens only about half its height. So from the same size window, a casement gives you a bigger opening to climb through. That matters most when a bedroom window is on the small side.
• Basements: casement, awning or slider. Basement windows are often small and high on the wall, where lifting a sash is hard. If the window sits in a window well, make sure there's room for a casement to swing open. And if a basement room is used as a bedroom, it needs a safe way out in an emergency too, so keep that in mind before you pick a style.
• Next to a deck, patio or walkway: double-hung. An open casement sticks out from the wall, right where people walk. A double-hung stays flat with the house.
• Rooms with a window air conditioner: double-hung. A standard window AC is made to sit under a sash that slides up and down.
• Older homes and the front of the house: often double-hung. Many older homes were built with double-hungs, and keeping that style keeps the look of the house from the street. Some homeowners keep double-hungs across the front and use casements where they work better, like the kitchen.
• Big views: casements beside a picture window. A pair of casements on each side of a large picture window gives you a wide view with fresh air at both ends.

Double-hungs also have a long track record around here. As our window and door page says, "Double-hung windows remain the most popular choice for Central Minnesota homes."

Casement or Double-Hung: A Quick Way to Decide

A casement may be the better fit if:

• You want the tightest seal against the wind when the window is closed.
• The window is hard to reach, like over a sink or counter.
• You want as much fresh air, or as big an escape opening, as you can get from one window.
• You like one clear pane of glass with no rail across the middle.

A double-hung may be the better fit if:

• The window opens onto a deck, patio or walkway.
• You run a window air conditioner in the summer.
• You want to keep the classic look of an older home.
• You'd rather not have a crank to look after.

Awning, Picture and Slider Windows: When a Third Option Wins

Sometimes neither style is the best fit for an opening.

• Awning windows are hinged at the top and swing out from the bottom. Like casements, they crank shut to a tight seal, and they can let in air during a light rain. They're common in basements and above or below larger windows.
• Picture windows don't open at all, so there's no moving sash to let air in. We recommend pairing them with windows that open nearby, so the room still gets fresh air.
• Slider windows (also called gliders) slide sideways. They work where there isn't room for a sash to swing out. Quality sliders have multiple weatherstripping points and interlock when closed to keep cold air out.

Replacement Casement and Double-Hung Windows: Price and Brands

Style is only one part of the price. The size of the window, the glass (double- or triple-pane), the frame material, the brand and the install all play a part. The easiest way to compare is to have both styles priced for the same opening. At Zablocki Roofing & Exteriors, we install windows from Andersen, Vector (Envision Series) and Sierra Pacific. Vector builds its windows in Fergus Falls, Minnesota, and makes its Envision Series in casement, awning, double-hung, single-hung, glider and picture styles, according to its product brochure. Our project specialists can walk you through the styles and options each brand offers for your home.

Frequently Asked Questions

Are casement windows more energy efficient than double-hung windows?

When they're closed, casements usually seal tighter, because the sash presses straight into the weatherstrip instead of sliding past it. Heat loss through the glass depends on the glass you choose, and you can get double- or triple-pane glass in either style. A well-built double-hung that's installed right can still seal well.

Which is easier to clean, a casement or a double-hung?

Both can usually be cleaned from inside. Many double-hungs have sashes that tilt in, and many casements open wide enough to reach the outside of the glass from the hinge side. Check the specific window before you buy, especially for second-floor windows.

Do casement windows freeze shut in winter?

Any window can freeze shut when moisture freezes the sash to the weatherstrip. With a casement, don't force the crank, since that can strip the gears. Let it thaw first. If your windows freeze shut often, too much moisture in the house may be part of the problem.

Can I replace my double-hung windows with casements?

Often, yes. A new window doesn't always have to match the style of the old one. Just keep in mind that a casement swings out, so it needs clear space outside, and changing styles on the front of the house changes how it looks from the street. Our project specialists can go over the options for each opening during your free estimate.

What's the most popular window style in Central Minnesota?

In our experience, double-hung windows remain the most popular choice for Central Minnesota homes. That doesn't make them right for every opening. Plenty of homes use double-hungs in most rooms and casements where a crank works better, like over the kitchen sink.
