Double-Hung vs. Casement Windows

Double-Hung vs. Casement · Which Window Wins

Double-Hung vs. Casement Windows The two most common operable window styles in DMV homes, compared honestly on sealing, airflow, cleaning, cost, and where each one belongs.

This is the question we get asked at almost every estimate. The honest answer is that neither one wins everywhere. They win in different rooms for different reasons. Here is the straight comparison so you can pick the right style for each opening in your home.

Quick answer

Double-hung windows have two sashes that slide up and down and suit traditional DMV homes, easy interior cleaning, and budgets. Casement windows hinge on the side and crank open, sealing the tightest of any operable window and catching a side breeze better, which suits kitchens, hard-to-reach openings, and homeowners who want maximum airflow and efficiency. Casements generally cost a little more and offer the best energy seal, while double-hung windows cost less and are the most familiar and versatile. Most homes use both, matched room by room.

Head to head

The Two Styles, Side by Side

Double-Hung

The classic DMV workhorse

Strengths

  • Both sashes tilt in for easy cleaning from inside
  • Open from the top, bottom, or both for balanced airflow
  • Lower cost per window than casement
  • Timeless look that fits colonials, ramblers, and townhomes
  • No sash swinging out into walkways, decks, or patios
  • Screens sit on the exterior, out of your living space

Trade-offs

  • Slightly less airtight seal than a casement
  • You reach across the sill to operate the lower sash

Casement

The airflow and efficiency champ

Strengths

  • Tightest seal of any operable window when closed
  • Sash swings fully open to catch side breezes
  • Effortless crank operation, great over a sink or counter
  • Unobstructed glass for a clean, modern view
  • Excellent energy performance from the compression seal
  • Easy to open even when reaching is awkward

Trade-offs

  • Sash swings outward, so mind decks, patios, and walkways
  • Generally costs a little more than double-hung
  • Screens sit on the interior side

Room by room

Which to Choose, Where

The smartest homes do not pick one style for the whole house. They match the window to the room.

Choose Double-Hung For

Bedrooms, living rooms, and traditional facades. If your home is a DMV colonial, rambler, or townhome, double-hung windows keep the look right and let you clean both sashes from inside, which matters on a second floor. They are also the budget-friendly choice when you are replacing a whole house full of openings, and they never swing out into a deck or walkway.

Choose Casement For

Kitchens, bathrooms, and hard-to-reach openings. Over a kitchen sink or behind a counter, a crank-open casement beats reaching across to lift a sash. Casements also deliver the tightest seal and the best side-breeze ventilation, so they shine on a wall that catches the prevailing wind, and their clean, unobstructed glass suits a more modern home.

“Homeowners think there is a right answer, like one style is just better. There is not. I tell people to walk their house room by room. Over the kitchen sink, put a casement, because cranking it open beats leaning across the counter every time. In the bedrooms, double-hung, because you can tilt both sashes in and clean them without a ladder on the second floor. We have been speccing windows since 1999, and the best projects almost always mix the two. Match the window to how you live in the room.”

Comparison questions

Frequently Asked Questions

Which is more energy efficient, double-hung or casement?
Casement windows have a slight edge because the sash presses into the frame and compresses a seal when you crank it closed, creating the tightest seal of any operable window. Double-hung windows are still excellent and meet ENERGY STAR in the same ProVia lines. For most DMV homes the difference is small, and proper foam sealing during installation matters more than the style you pick.
Are casement windows more expensive than double-hung?
Generally yes, casement windows cost a little more per window than double-hung, because of the crank hardware and hinge mechanism. The difference is usually modest. On a whole-house project, many homeowners use lower-cost double-hung in bedrooms and bay areas and spend a bit more on casements only where the crank operation and tight seal really pay off, like kitchens.
Which is easier to clean?
Double-hung windows have a slight edge for cleaning because both sashes tilt inward, letting you wash the exterior glass from inside, which is a real advantage on upper floors. Casements are also easy to clean because they crank fully open and you can reach the outside glass, but on a high second-story opening, the tilt-in double-hung is the simpler choice.
Can I mix double-hung and casement windows in the same house?
Absolutely, and we recommend it. The best window projects match the style to the room: casements over kitchen sinks and in hard-to-reach spots, double-hung in bedrooms and on traditional facades. Both come in the same ProVia lines with the same glass and finish options, so they look cohesive from the street while each one works best for its room.
Do casement windows seal better for noise and drafts?
Yes. Because a casement sash compresses against the frame when cranked shut, it seals very tightly, which helps with both drafts and outside noise. If a quiet, draft-free room is the priority, such as a bedroom facing a busy road, a casement paired with the triple-pane option on the ProVia ENDURE line is a strong combination.
Which style is better for a traditional DMV colonial?
Double-hung windows are the classic match for a colonial, rambler, or townhome and keep the traditional look that fits the architecture and most HOA and historic-district expectations. You can still add casements in the kitchen or a modern addition without clashing, since both styles share the same frame profile and color options in the ProVia lines.
