Contemporary uPVC Sash Windows
Our Contemporary collection has many fantastic features at a more inclusive price. These windows offer a similar
aesthetic to our Traditional PVCu Collection with run-through horns and a mechanical joint across the mid-rail, ensuring
a harmonious blend among Traditional and modern neighbouring properties. These windows are highly robust and
provide high levels of security and insulation.


Our Contemporary uPVC sash windows deliver the elegant aesthetics of traditional timber with next-generation performance, affordability and low maintenance.
Sculpted frames and sashes replicate heritage detailing like decorative horns and mechanical rail joints, allowing installation in period homes and modern spaces alike. The sliding sashes operate smoothly and independently with a concealed balance mechanism, tilting inwards to facilitate safe and easy cleaning. We ensure structure integrity in larger windows through steel-reinforced internal chambers, while advanced multi-chambered framing enhances thermal efficiency, weatherproofing and noise insulation.
