What is a Casement Window?
Casement window is a hinged windows that open outward like a door, operated by a crank mechanism. Unlike slider windows or double hung windows, they provide unobstructed views and maximum ventilation.
Historical Context and Evolution
- Originally developed in medieval Europe
- Evolved from simple hinged designs to modern crank operations
- Gained popularity in North America during the 20th century
- Modern innovations in materials and technology
| Feature | Benefit | Technical Details |
| Crank Operation | Easy to open and close | Fold-away handle design |
| Multi-point Locking | Enhanced security | 2-4 locking points |
| Compression Seal | Superior weatherproofing | Double weather-stripping |
| Full Opening | Maximum ventilation | Up to 90-degree opening |
| Outward Swing | Space-efficient design | Clear interior space |
| Insulated Frame | Energy efficiency | Multi-chamber design |

Frequently Asked Questions
Can a casement window be installed horizontally?
No, casement windows are designed for vertical installation only. Horizontal installation would compromise the window’s operation, weatherproofing, and durability. Window manufacturers specifically design these windows for vertical mounting during replacement windows installation.
Can casement windows open inward?
Most casement windows are designed to open outward only. While some European window manufacturers produce inward-opening models, the standard North American window style opens outward for better weatherproofing and operation.
Can you install a casement window sideways?
No, installing a casement window sideways would prevent proper operation and void the warranty. Professional window installation must follow manufacturer specifications for optimal performance and longevity.
How far do casement windows open?
Typical casement windows open up to 90 degrees, allowing for maximum ventilation and easy cleaning. The exact opening angle may vary between window manufacturers and specific window styles.
How long do casement windows last?
With proper maintenance, casement windows typically last 20-30 years. Quality replacement windows from reputable window manufacturers can extend this lifespan, especially in well-maintained installations with quality hardware.
How to keep casement windows open?
Casement windows stay open using their integrated crank mechanism and window operator. Regular maintenance of these components during window installation or replacement ensures smooth operation and reliable positioning.
