Boost Your Home's Efficiency with Casement Windows

Here’s why we recommend casement windows for energy efficiency: 

Superior Sealing: Unlike sliding windows with tracks that can become loose over time, casement windows crank open and shut, creating a tighter seal against the frame. 

Reduced Infiltration: With a strong seal on all four sides, casement windows effectively prevent drafts. This means less hot air sneaks in during the summer and less cold air escapes in the winter, keeping your home comfortable and reducing the strain on your climate control systems. 

Low-Emissivity (Low-e) Coating: This invisible layer on the glass reflects heat back inside during winter and deflects it outwards in summer, significantly improving your home’s thermal performance.

Warm Edge Spacers: These spacers minimize heat transfer around the edges of the glazing unit, reducing energy loss and further enhancing your window’s efficiency

How to Maintain Casement uPVC Windows

Maintaining your uPVC casement windows is key to their longevity and performance.

uPVC: We recommend cleaning uPVC frames every few months, perhaps quarterly. You can use warm soapy water and a soft cloth or sponge. For more stubborn dirt, a specialized uPVC cleaner is a good option. Avoid abrasive cleaners as they can scratch the surface.

You can use a standard household glass cleaner and a clean, lint-free cloth. For particularly dirty windows, you might pre-wash them with warm soapy water. Always dry the glass thoroughly to avoid streaks.

Casement Windows Insulation

When you choose Horizon Windows, your new casement frames do more than look good – they lock in warmth, drive down bills and make every room feel calmer and cosier. 

All-round compression gasket – as the sash swings shut, a weather-tight seal presses against the frame on every side, blocking draughts that sliders and double-hungs often leak through.

Multi-point locks pull the sash tight to that gasket, improving both security and air-tightness in one turn of the handle.

Double- or triple-glazed Low-E units filled with argon or krypton trap heat inside in winter and reflect solar gain in summer, cutting heat transfer by up to 70 % compared with obsolete single panes.

uPVC multi-chamber frames add layers of insulating air pockets, keeping the edge of the glass warmer and reducing condensation.

Your Casement Window Questions Answered

Yes, Casement windows are often considered better due to their energy efficiency, ease of operation, and ability to provide excellent ventilation. They open outward like a door, allowing for a larger opening compared to sliding or double-hung windows. This makes them ideal for airflow and natural light. Additionally, they tend to seal tightly when closed, improving insulation and energy savings.

No, casement windows are generally harder to break into compared to other window types. They open outward and are often equipped with a locking mechanism that secures the window tightly when closed. The fact that they are hinged on the side also makes it more challenging for burglars to force them open compared to sliding or double-hung windows.

Casement windows are hinged on one side and open outward, similar to a door. They usually have a single large pane of glass, which makes them ideal for unobstructed views and maximizing natural light. These windows can be found in various sizes and frame styles, but they are characterized by their outward-swinging design.

To secure casement windows, you should install a high-quality locking mechanism. Additionally, consider using window security pins, which prevent the window from being opened even if the lock is bypassed. You can also add metal or security bars on the inside for extra protection. Another option is to install a secondary locking device or a key-operated lock to ensure the window remains securely shut when not in use.
