Looking for a contemporary feel

“We loved the developers’ original vision for the barn with the large picture windows and open out bi-folds. However, for us, it was the switch to aluminium from PVC-U which really made the difference. The AluK products have given us exactly the contemporary feel that we wanted, while the Chartwell Green finish successfully softens the overall look.“

Delighted with the authentic look

“As with any owners of a listed property, finding the right company to take time to understand our requirements and provide a bespoke product and carefully tailored service was key. We considered other options, but the team at Tradeglaze have been terrific and their AluK Heritage windows, with an authentic look and excellent weather performance, were ideal for our property and for getting our planning permission approved. We are delighted, and the look and feel are exactly what we had hoped for.”
