What Are Casement Windows?
Casement windows are side-hinged and usually open externally. They offer full ventilation and you can even fully open them up to the elements for air, light, and view.
Pros of Casement Windows
- Maximum ventilation — Open completely for air to circulate.
- Easy to use — Opened and closed easily with a simple crank.
- Energy-efficient casement windows – Lower heat loss and save on heating bills.
- Easy to clean – A lot of models tilt inward for easy maintenance.
- Additional security from high-quality locking systems.
Cons of Casement Windows
- Need space outside because they open outwards.
- Hinges might require upkeep in humid areas.
- Usually more expensive than sliding windows.
What Are Sliding Windows?
Sliding windows run side to side in a horizontal rail and stay closed or overlapping when not in use. They are cost friendly and work well in apartments or places with limited outdoor space.
Pros of Sliding Windows
- Sliding windows are simple to work with and manage.
- Space-efficient – Panels slide instead of swing.
- Provides broad openings for light and view.
- Requires less maintenance because of fewer moving parts.
Cons of Sliding Windows
- Ventilation is limited; only one panel opens at a time.
- Not as airtight as energy efficient casement windows.
- Tracks need to be cleaned often in order to avoid jamming.
