Take a look at many different styles of British home and you’ll more than likely notice that they have one thing in common – most, if not all, will have a casement window of some description. This design classic has been a staple of British architecture for centuries, offering an elegant and practical solution for homeowners.
Combining traditional craftsmanship with modern technology, timber casement windows provide excellent thermal insulation, energy efficiency and durability. Whether you’re restoring a period property or looking for high-quality replacement windows, understanding the different types of timber casement windows will help you make the best decision for your home.
A brief history of timber casement windows
Casement windows date back to the late 18th century. Initially, all timber casement windows were flush with the frame, a design commonly found in cottages and smaller homes. However, as architectural needs evolved, the lipped casement window emerged to provide additional protection against bad weather.
Today, both flush and lipped casement windows are popular choices, with modern manufacturing processes ensuring that each type offers excellent thermal insulation and weather resistance. The primary difference between the two lies in how the casement sits within the window frame.
Flush Casement Windows
Flush casement windows feature a design where the casement sits level with the outer edge of the window frame when closed. This style of window is often associated with traditional properties but is also a sleek, understated choice for contemporary homes. Modern flush casement windows have been developed to withstand the test of time, offering superb weather resistance and energy efficiency.
Benefits of flush casement windows:
- Traditional aesthetics suitable for period homes
- Smooth, streamlined appearance for modern properties
- Excellent energy efficiency with double glazing or triple glazing
- Long-lasting durability with proper maintenance
Lipped Casement Windows
Lipped casement windows were developed as a solution to early issues with water ingress in flush casement designs. The casement slightly overlaps the outer surround of the window, creating an extra barrier against wind and rain. This additional protection makes lipped casement windows particularly suited for properties exposed to harsh weather conditions.
Advantages of lipped casement windows:
- Increased weather resistance and additional protection
- A more contemporary look while still maintaining a traditional feel
- High thermal insulation for energy efficiency and reduced energy costs
- Suitable for a range of property styles, from heritage homes to modern builds
Choosing the right timber for your casement windows
Timber casement windows can be crafted from a variety of hardwoods and softwoods, each offering distinct advantages.
- Hardwood (e.g. oak, sapele, idigbo): Known for its exceptional durability, hardwood is a great choice for homeowners looking for long-lasting windows with minimal maintenance. It is naturally resistant to warping and provides a beautiful grain that can be finished with a wood stain.
- Softwood (e.g. pine, larch): A more cost-effective alternative, softwood is versatile and widely used in window manufacturing. Modern treatments and laminating techniques make softwood windows just as durable as hardwood, with the added benefit of a smooth, paintable finish.
Whether you opt for hardwood or softwood, all timber windows should be sourced from sustainable materials to ensure environmental responsibility and longevity.
Why choose timber casement windows?
Timber casement windows continue to be a popular choice due to their combination of aesthetics, energy efficiency and durability. When properly maintained, they can last for generations, offering a reliable and attractive solution for any property style.
Key Benefits:
- Energy Efficiency: Timber is a natural insulator, reducing heat loss and lowering energy costs.
- Sustainability: Responsibly sourced wood ensures an environmentally friendly choice.
- Customisation: Available in a range of styles, colours, and finishes to match design preferences.
- Long Lifespan: With regular care, timber windows can last a lifetime.
