Flawless Flush Casement Windows

Flush casement windows are a timeless addition to your home and can add significant curb appeal to your property. Dating back to the early 19th century, casement windows were a hallmark of British architecture and were commonly seen in Georgian, Victorian and Edwardian properties.

Our flush casement windows combine traditional casement window designs with modern-day security, thermal and weather-proof enactments for a truly authentic and lasting build quality.

All flush casement windows are designed, built and installed by our team in accordance with the Secured by Design standards. We provide two types of flush casement windows at Sash Windows London Ltd:

Timber Flush Casement Windows

Our timber casement windows are designed to mimic single-glazed windows while harbouring the added benefits of double glazing. This allows us to design windows that fit the appearance of your property with no compromise on insulation or draughting problems. Attention to detail is essential in timber casement windows and we work hard to ensure your final design compliments your property. Both lipped and flush casement timber windows can be supplied with either top or side openings.

Security is one of our main priorities, and you can rest assured your timber casement windows feature internal multi-point locking mechanisms and shoot bolts to guarantee a secure, compact lock and all our windows are internally glazed.

We can also imitate and replicate a variety of windows, including replacement bays, incorporation of intricate detailing and replication of stained glass. Your windows are made bespoke to order, so there is no limit regarding customisation.

Our timber casement window options can be found below:

Timber Flush Fit Casement

Timber flush fit casement windows are typically found on period properties. Flush casement windows are designed to sit within the window frame for slim design and appearance.

Each timber flush casement window features variations on bar thicknesses and dummy butt hinges. This means that your window’s traditional character is maintained but is also supported with modern technology.

What properties benefit from this window style?

We are able to install timber flush casement windows on most properties, but they benefit most and fit perfectly with period properties such as listed buildings, farmhouses and barn conversions, especially those governed by conservation requirements.

Timber Lipped Casement

Otherwise known as storm-proof, our timber-lipped casement windows are built to allow the opening sash extending from the frame to offer exceptional gasket compression to ensure excellent weather and storm resistance. This style comes in both traditional and contemporary profiles.

What properties benefit from this window style?

Our timber-lipped casement windows are modern-style windows suitable for high-end new builds and similar properties. They are perfect for properties that require additional protection from the weather (if your property is situated along a coastline, for example).

Windows feature traditional ovolo moulding and bars, fixed sash for non-opening lights, casement stays, night vents and easy cleaning friction hinges as a standard.
