Optima Flush Casement Window
Replicating the authentic looks of traditional timber frames, our flush casement windows combine classic cottage styling with thermal performance and modern security.
Why Choose Profile 22 Flush Casement Windows?
Warmth & Efficiency
The Profile 22 Flush Casement range features an advanced 6-chambered outer frame design equipped with recycled thermal (RCM) inserts to deliver superb insulation. Combined with high-performance double glazing, the system easily achieves an impressive A+ Window Energy Rating (WER) to keep heating costs under control. Standard co-extruded gaskets, alongside options for a premium second and third weather seal, work together seamlessly to shut out seasonal grime, dampness, and driving rain.
Strength & Security
Replicating traditional timber frames does not mean compromising on property protection. Built on the industry-leading 70mm Profile 22 system, our flush casement frames feature intelligent internal design details—including integrated support webs to counter weld sink—ensuring flawless structural integrity. The entire system is engineered with easy-to-locate hardware tracks that securely house heavy-duty multi-point locking mechanisms. This allows trade installers to deliver an authentic heritage appearance that effortlessly meets strict PAS24 Enhanced Security compliance right out of the box.
A Perfect Fit for Any Project
Whether you are working on a traditional British cottage, a heritage property renovation, or a modern self-build looking for a sleek finish, this versatile system makes the installation straightforward. The sashes sit completely flush within the outer frame, recreating a beautifully balanced, historic look that can be enhanced with an optional deep bottom rail, monkey-tail handles, and dummy peg stays. Standard Profile 22 outer frames and ancillaries ensure perfect compatibility with our full branch stock of cills and trims, giving trade customers everything they need to handle the unique structural variations found in older properties.

Custom Styling & Hardware Finishes
Our Flush Casement windows offer complete design flexibility, allowing you to tailor the finish to suit both contemporary new-builds and traditional heritage projects. For a beautiful, classic look, the frames can be configured with elegant internal Georgian bars or traditional astragal bars, flawlessly paired with authentic period hardware like monkey-tail handles and dummy peg stays. Alternatively, for minimalist architectural projects, they can be left entirely clean to emphasise the perfectly flat, smooth sightlines of the flush frame. To complete your layout, our heavy-duty handles and premium friction hinges are engineered for smooth, dependable daily operation across a wide selection of durable finishes.
Simple Care & Maintenance
Keeping your Profile 22 uPVC frames in top condition is incredibly straightforward. A quick wipe down with warm, soapy water and a soft cloth is all they need to remove seasonal grime and atmospheric deposits from the smooth, flat surfaces. Just be sure to steer clear of abrasive household cleaners, ammonia, or harsh solvents, which can scratch the glass or score the uPVC surface. Twice a year, pop a few drops of light 3-in-1 machine oil onto the moving pivot points, friction hinges, and locking mechanisms to keep your Flush Casement windows opening, closing, and deadlocking smoothly for years to come.

The key difference is in the layout of the opening frame. On a standard casement window, the opening sash stands proud and lips over the outer frame. With a flush casement, the sash sits completely level and flat within the frame when closed. This creates a smooth, uniform exterior surface that beautifully mimics traditional timber joinery or sleek, modern architectural glazing.
Absolutely. The Profile 22 Flush Casement system has been meticulously engineered from scratch to replicate the authentic proportions of historic British cottage and period timber windows. With design options like a traditional deep bottom rail, mechanically jointed outer frames, internal Georgian bars, and heritage ironmongery (including monkey-tail handles and dummy peg stays), you get a convincing timber look without any of the sanding, painting, or warping headaches.
They offer market-leading weather protection. Because they sit completely flush, the seals are highly optimised to lock out wind and dampness. The system features a standard high-performance co-extruded gasket, along with options to add a premium second and third weather seal. Coupled with a 6-chambered outer frame and integrated support webs that counter weld sink, the frames maintain total structural integrity and a weather-tight seal in the toughest conditions.
Despite their slim, traditional sightlines, they deliver outstanding thermal performance. Built with an advanced 6-chambered profile and recycled thermal (RCM) inserts, the system easily achieves an impressive A+ Window Energy Rating (WER) with standard high-performance double glazing. This keeps your property highly insulated and ensures full compliance with modern UK building regulations.

Please check this carefully before signing off — all items are custom-manufactured to these exact specifications and cannot be refunded or altered once production has started.rnrnResponsibility for measurement accuracy rests with the customer.
