Chartwell Green uPVC Casement Window — Made to Measure, A-Rated Performance

Looking for a window that combines striking kerb appeal with genuine thermal efficiency? Our Chartwell Green uPVC Casement Window delivers both. The soft, muted sage tone of Chartwell Green has become one of the UK’s most sought-after window finishes — complementing period cottages, Victorian terraces, and modern new-builds alike — and our precision-engineered profiles ensure your investment looks as good in 20 years as it does on day one.

Why Choose Our Chartwell Green uPVC Windows?

Built on a 70mm thermally efficient multi-chamber frame, our double glazed uPVC windows achieve an outstanding U-value of just 1.3 W/m²K — meeting and exceeding the requirements of Part L Building Regulations. Argon-filled 28mm sealed units with soft coat low-E glass and a warm-edge black superspacer bar work together to reduce heat loss, cut energy bills, and keep your rooms comfortable year-round.

Unlike timber windows that demand constant repainting and maintenance, these uPVC casement windows are engineered for lifelong low maintenance. The Chartwell Green finish is co-extruded into the profile — it will not peel, warp, discolour, or fade, and is backed by a 10-year profile guarantee.

Slim, Sculptured & Secure

Ultra-slim sightlines give these windows a clean, modern look while maximising your glass area and the natural light entering your home. The fully sculptured profile adds visual depth and shadow lines that replicate the appeal of traditional painted timber — without any of the upkeep.

Security is built in at every stage. Internal glazing beads mean the glass cannot be removed from outside, while the multi-point locking system and lockable push-button handle provide solid, tested resistance against forced entry.

Premium Weatherproofing

Patented double-action ‘bubble’ gaskets run the full perimeter of every opening vent, maintaining a tight, consistent weather seal even under sustained wind and rain pressure. Whether you’re in an exposed coastal location or a city terrace, these windows are engineered to perform.
