Casement impact windows
Side hinged, crank operated, and the only type that opens the whole opening.
Specifications
How it works
- Operation
- Hinged at the side, opened with a crank
- You wind it open rather than pushing it, which is why it works over a kitchen sink or anywhere you cannot reach the far edge.
- Ventilation
- The whole opening
- The only type that gives you 100%. The open sash also catches side breezes like a sail, which no sliding window does.
- Air seal
- Compression seal, multipoint lock
- Closing it pulls the sash onto the frame all round instead of sliding past it, so it seals better than any sliding type and reaches high design pressures.
- What to watch
- The sash swings outward
- It projects over whatever is outside. Next to a walkway, a driveway or a neighbour’s path, that is a real constraint and we will say so.
What to ask for
- Impact rating
- Large Missile — TAS 201, 202 and 203
- The Miami-Dade test protocol.
- Design pressure (DP)
- On the NOA, per model and per size
- The pressure the unit is approved to take.
- Product approval
- Miami-Dade Notice of Acceptance
- The document that makes the unit legal here.

The best air seal of any operable type when closed
Multipoint locking, which means both better security and higher design pressure

About casement windows
Why does it cost more than a slider?
More hardware, and hardware that has to hold a sash out in the wind: hinges, an operator, and a multipoint lock. You are paying for the ventilation and the seal, and if neither of those matters at that opening, a roller is the better buy.
Is there a width limit?
Yes. The arm has to carry the sash, so casement is limited in width in a way that a slider is not. Tall and narrow is where it excels. For a wide opening we would put a fixed unit in the middle and casements at the sides.
How does the hardware hold up in salt air?
The crank and hinges are exposed moving parts, so ask for the stainless package rather than the standard one. About ten miles inland, in Doral, this is a sensible precaution; on the beach it is not optional.
