Box Sash Windows – Elegance

Box Sash Windows – Elegance

...

Vertical sliding box sash windows offer slim sight lines, a large glass area, a wide range of design options and flexible solutions for period properties or new build. This window style originated in the 17th century and continues to offer elegant glazed opening solutions with optimum ventilation and practicality guaranteed.

The KAT Elegance is modern, secure, virtually maintenance free and manufactured from high impact, durable uPVC. The Elegance has all the features and benefits of the KAT Classic range with an even more substantial frame and flush features. They are hand crafted to your dimensions by us in Macclesfield, using very similar skills and techniques to those employed in our joinery workshop.

The thermal properties of uPVC are excellent and these windows can be supplied in a wide range of finishes. From six feet away it is extremely difficult to tell if the window is timber or uPVC.
