At Clement, we manufacture slender Jansen steel profile windows which meet the highest requirements of thermal insulation, security and fire protection, as well as mechanical strength and longevity. Suitable for restoration work as well as new build projects, these slim frames can be fitted into all opening types.
Clement offer the following Jansen window systems:
We offer five different styles of glazing, from clear glass, to genuine lead in an arrangement to match the pattern of your original leaded lights, to the G+ and Fenestra joint systems which are unique to Clement. All of these options have superb features which faithfully replicate those of original steel windows.
Our steel windows are hot dip galvanized and available in a choice of highly durable Akzo Nobel powder paint colours. Clement Windows provide an average paint coating in excess of 100 microns on flat surfaces – the industry standard calls for 60/70 microns. Order from a wide range of RAL colours to match your scheme or choose different colours for the inside and outside of your windows.
