Flush Casement Windows: The Ultimate Timber Alternative

For many years, homeowners in Kenilworth and across Warwickshire had to choose between the authentic look of traditional timber or the modern performance of uPVC. With our Flush Casement Windows, you no longer have to compromise.

These windows are designed so the sash sits “flush” within the frame, replicating the clean, flat exterior of 19th-century joinery. Whether you live in a heritage cottage or a contemporary new build, our flush sashes provide a sophisticated, minimalist finish that instantly boosts curb appeal.

Engineered by Selecta, Crafted by Hillingdon

Quality starts with the right ingredients. That’s why we manufacture our flush windows using the Advance 70 System from Selecta.

As a leading UK extruder, Selecta’s Advance 70 profile is renowned for its strength and thermal insulation. By combining their world-class British engineering with our local manufacturing expertise, we create a window that is:

Aesthetically Perfect: Symmetrical and slim with no overlapping “lips.”
Thermally Superior: Multi-chambered profiles that trap heat and exceed building regulations.
Built to Last: Fully guaranteed uPVC that won’t warp, rot, or require painting.

Modern Technology, Traditional Heart

Our flush casements may look like traditional wooden windows, but they perform to 21st-century standards.

Timber-Look Aesthetics: We offer a range of authentic woodgrain foils and heritage colours (like Agate Grey, Anthracite, and Chartwell Green) to mimic the feel of painted timber.
Enhanced Security: Every window is fitted with high-security multi-point locking systems and friction stay hinges as standard.
Advanced Weather Sealing: Double weather seals ensure that even the harshest Warwickshire storms stay outside, keeping your home draught-free and quiet.

Your Choice of Finish

Because we manufacture these windows in our Kenilworth factory, we give you total control over the final look. Choose from:

Fully Welded Joints: For a smooth, modern, and incredibly strong corner finish.
Mechanical/Timber-Look Joints: For the most authentic replica of a traditional mortise and tenon joint found on original wooden windows.
