Casement windows remain one of the most popular window styles throughout London thanks to their versatility, excellent thermal performance and timeless appearance. Whether you’re renovating a Victorian property, extending your family home or replacing ageing windows, modern timber casement windows offer an ideal balance between traditional craftsmanship and contemporary engineering.
At International Windows Group, we manufacture bespoke timber casement windows designed specifically for each property. Every window is built to order using premium engineered timber, modern glazing technology and high-quality hardware, ensuring long-lasting performance and exceptional appearance.
What Are Casement Windows?
Unlike sash windows, casement windows open outward on side-mounted hinges. This simple yet highly effective design provides excellent ventilation, outstanding weather resistance and impressive thermal insulation.
Our bespoke Timber Casement Windows are suitable for both traditional and contemporary homes across Greater London.
Benefits of Timber Casement Windows
- Excellent energy efficiency
- Superior weather sealing
- High security locking systems
- Wide opening for natural ventilation
- Low maintenance engineered timber
- Made-to-measure for every property
Because every window is manufactured individually, homeowners can choose the size, glazing configuration, paint finish and hardware that best suits their property.
Energy Efficiency Matters
Replacing older timber or uPVC windows with modern engineered timber casement windows can significantly improve thermal performance. Modern glazing, weather seals and precision manufacturing help reduce heat loss while improving comfort throughout the year.

Reducing Outside Noise
For many London homeowners, noise reduction is just as important as thermal insulation. Our casement windows can be fitted with acoustic glazing designed to reduce traffic, railway and aircraft noise while maintaining excellent thermal performance.
