Jansen’s Steel window range moves steel window and door thermal efficiency, weather sealing and security to a new level while retaining ultra-slim sightlines.
Redefining the thermal performance of steel windows
Jansen has developed an advanced, uyltra thermally efficient steel window system which achieves u-values of as low as 0.8W/m2K, a Passiv Haus equivalent level of performance.
With a range of options specially designed for the renovation of industrial and loft-type windows ultra-slim profiles meet advanced levels of performance.
Windows and doors are a big purchase, so making time to get it right is important. We think there’s no replacement for seeing windows and doors ‘in the flesh’, opening and closing them and picking out the fine detailing that brings the all-important finishing touches to your project.
With showrooms in Banbury and Beaconsfield, we bring our product ranges closer to you.
Our Window and Door Design Centre, is located 15 miles north of Oxford in Banbury and carries our complete product range.
