Chartwell Green uPVC Double Casement Window with Fixed Centre — Full-Height Glazing, Unrestricted Airflow

Clean lines. Full-height glass. A wide open view and the option to throw the window wide open on both sides. Our Chartwell Green uPVC Double Casement Window with Fixed Centre is one of the most straightforward and satisfying window designs available — and sometimes straightforward is exactly right.

No top lights breaking the vertical sightline. No horizontal rails interrupting the view. No compromise between the glazing area you want and the ventilation you need. Just three full-height panes of A-rated double glazing in a sculpted Chartwell Green frame, with generous opening casements on both sides and an unobstructed picture pane in the centre.

This is the window for rooms that deserve to feel open — and for homeowners who want a window that simply works, beautifully and reliably, for decades.

Full-Height Opening on Both Sides

The defining characteristic of this design is its full-height side-hung casements. Unlike combination windows where the opening vent is restricted to the upper portion of the frame by a fixed lower pane, both casements here open from sill to head — the full height of the frame, uninterrupted. The result is a ventilation opening that is genuinely generous, allowing air to move freely into the room at every level simultaneously rather than just at the top.

Both casements swing outward on their hinges, giving you complete control over airflow. Open both fully for maximum through-ventilation on warm days. Open one partially for a gentle background breeze. Open both wide after cooking or during exercise to clear the air in minutes. The full-height opening also makes cleaning the outer face of the glass straightforward from inside — a practical advantage that becomes more valuable the higher up the window is positioned.

The wide central fixed pane between the two casements requires no operation at all. It is the visual and structural heart of the window — a broad, clear panel of thermally efficient double glazing that frames your view without interruption and brings natural light deep into the room.

Vertical Proportions That Open Up a Room

There is a reason full-height glazing feels so different from a window with a horizontal rail. When the glass runs from sill to head without interruption, the eye reads the opening as taller than it is, the room feels larger and more connected to the outside, and natural light reaches further into the interior. This effect is most pronounced in rooms with standard ceiling heights — where a horizontal rail at mid-window level can make the space feel visually compressed.

This three-light design avoids that entirely. All three panes run the full height of the frame, and the slim vertical dividers between them are the only elements breaking the horizontal expanse of glass. In Chartwell Green, those dividers add definition and character rather than visual weight — the fully sculptured profile creates clean shadow lines that give the frame presence without bulk.

A-Rated Thermal Performance Throughout

Every pane in this double glazed uPVC window is built to the same uncompromising thermal specification. The 70mm multi-chamber uPVC frame, 28mm argon-filled sealed units, soft coat low-E glass, and warm-edge black superspacer bar deliver a U-value of just 1.3 W/m²K — A-rated performance that meets Part L Building Regulations and makes a genuine difference to heat retention across the full width of a wider opening.

The soft coat low-E glass coating reflects heat radiation back into the room during winter while allowing solar gain during the day — working with the seasons rather than against them. The argon fill between the panes slows convective heat transfer. The warm-edge superspacer eliminates the cold strip at the glass edge where condensation typically forms on lower-specification units. Every element of the specification is there for a reason, and the combined effect is a window that performs as well in January as it looks in July.

The Enduring Appeal of Chartwell Green

Chartwell Green is not a trend — it is a fixture of quality British window design that has grown steadily in popularity precisely because it works on so many property types and in so many contexts. On a full-height three-light design like this one, the colour has particular impact. The slim vertical dividers and the clean horizontal head and sill create strong geometric lines, and the soft sage tone of Chartwell Green sits within those lines with a confidence that white uPVC simply cannot match.

The finish is co-extruded into the uPVC profile — not painted, not foiled, not applied as a coating — making it immune to peeling, fading, chipping and discolouration regardless of weather exposure or UV intensity. The 10-year profile guarantee covers both the frame and the finish, and the practical maintenance requirement is nothing more than an occasional wipe with a damp cloth.

These uPVC casement windows are the kind of upgrade that changes how a room feels as well as how a house looks — and on a wide opening with full-height glazing, that effect is immediate and lasting.

Security From Sill to Head

Both full-height casements are secured with multi-point locking systems that engage at multiple points along the full height of the frame — not just at the handle — providing robust resistance to forced entry across the entire length of the opening edge. Lockable push-button handles are fitted as standard to both casements. The central fixed pane and all glazed sections are retained by internal glazing beads, preventing any section of glass from being removed from outside the property. Patented double-action bubble gaskets run the full perimeter of both opening casements, maintaining a consistent, draught-proof weather seal in all conditions.

When Simple Is the Right Answer

Not every window needs a complex arrangement of top lights, combination vents and asymmetric layouts. Sometimes the room calls for a wide opening, full-height glass, generous ventilation on both sides, and a clean Chartwell Green frame that lets all of those things speak for themselves. This double casement with fixed centre is that window — resolved, proportionate, and built to perform for a generation. It is one of the most timeless and universally applicable designs in our entire Chartwell Green uPVC window range.
