Casement Windows in Tulsa, OK
Hinged on one side, a casement cranks open like a small door. It catches breezes a sliding window misses, and it presses shut against the frame for a tight seal.
Style example · Casement windowWhere casements earn their keep
The crank makes them easy to open where you can’t reach to push a sash: over a kitchen sink, behind a counter, above a tub. Opened wide, the sash scoops in a side breeze. Closed, it presses into the weatherstripping instead of sliding past it, so a casement tends to leak less air than a sliding or hung window.
Good to know
A casement swings outward, so it needs clear space outside, not a walkway or deck where someone passes at head height. The screen goes on the inside. For a wide, short window, look at awning windows: they crank open the same way, hinged at the top.
Locks and glass
Multi-point locks pull the sash tight at several spots when you crank it shut, which also makes it hard to force from outside. Dual-pane Low-E glass suits most homes; triple-pane is available. Frame colors to match your trim.

Common questions
Are casement windows more efficient than other styles?
Often, yes. The sash presses into the seal when it closes, so it tends to leak less air than a sliding or double-hung window installed just as well.
Can a casement go over a sink or counter?
That’s one of the most common places for one. The crank sits at the bottom of the frame, so there’s no long reach.
Do I need triple-pane glass in Oklahoma?
Most homes do fine with dual-pane Low-E. Triple-pane is available, and we’ll help you weigh whether it’s worth the extra cost for your house.
How much upkeep do casement windows need?
Very little: keep the hinge track clear, and give the crank a little lubricant now and then.
