Something quite remarkable has happened in the world of window design. After years of modern uPVC windows looking, well, distinctly modern, we've finally cracked the code on creating windows that genuinely fool the eye. The new Timberlook uPVC Flush Casement Windows don't just look like traditional timber windows – they're virtually indistinguishable from the real thing, but with all the benefits of 21st-century technology.

Let's be honest – we've all seen those replacement windows that stick out like a sore thumb on period properties. You know the ones: they've got those telltale mitred corners and chunky profiles that scream "modern replacement." Timberlook has taken a completely different approach. These windows feature authentic mortise and tenon-looking joints, just like traditional timber windows, with none of those giveaway diagonal welds you'd normally expect from uPVC.
The slim 60mm sash profile perfectly replicates the proportions of heritage timber frames, while the flush exterior finish creates that classic aesthetic that conservation officers actually approve of. We're talking about windows that have been accepted for use in the heart of The Cotswolds – and if they can pass muster there, they'll look perfect on your property too.

Here's where things get really interesting. While these windows look like they've been around for centuries, they perform like the modern marvels they actually are. The 70mm frame depth provides excellent thermal efficiency, significantly outperforming traditional timber windows. You're getting contemporary comfort levels with period charm – and without the ongoing maintenance nightmare that comes with real timber.
Think about it: no more annual painting, no warping in wet weather, no swelling that makes windows impossible to open on humid days. These windows simply don't require that level of fuss, yet they maintain their stunning appearance year after year. It's the kind of practical magic that makes renovation projects actually enjoyable rather than endlessly demanding.

Modern living demands modern security, and Timberlook delivers with Document Q compliance and PAS24 certification. The dual-setting night vent system is particularly clever – it allows for secure ventilation without compromising safety. These aren't just pretty windows; they're properly engineered for contemporary security requirements while maintaining that authentic heritage appearance.
The espagnolette locking system provides smooth operation with enhanced security that easily meets current standards. You're getting the peace of mind that comes with modern security technology, hidden within a design that looks like it belongs to a different era entirely.

The colour palette has been thoughtfully curated to complement buildings of any age. From the natural tones of Cotswold Cream that work beautifully with stone properties, to the contemporary Smooth Anthracite Grey that coordinates perfectly with modern aluminium doors, there's genuinely something for every project. The Painswick grey-green option has become particularly popular – it's that perfect heritage colour that seems to work with everything.
What's really clever is the dual-colour option. You can have one finish on the exterior to match your property's character, and a completely different colour inside to coordinate with your interior design. It's this kind of flexibility that makes these windows work for real-world renovation projects, not just show homes.

While the windows look beautiful with their standard contemporary cill, the optional Radlington Cill is what transforms them from good to absolutely stunning. This deeper 55mm cill is a modern interpretation of the timber block cills found on traditional windows. It's that kind of authentic detail that makes all the difference between a window that looks right and one that looks perfect.
The Radlington Cill also solves practical installation challenges. Old imperial bricks varied in height, and traditional timber cills were designed to align with brick courses. This modern interpretation allows for packing, expansion, and those inevitable irregularities in older properties, making installation smoother while creating a more authentic final appearance.
