Kömmerling vertical sliding sash windows allow you to enjoy the best of both worlds. Suited for use on both period and modern properties, they deliver all the benefits of modern PVCu windows but in a design that retains a traditional and time-honoured appearance..

Technology meets tradition
Manufactured to maintain the elegant proportions of traditional sash windows, whilst incorporating the very best of modern technology, our system enables you to enjoy the low maintenance and high security of PVCu without the problems associated with timber sash windows. Your new windows are guaranteed for ten years as they are manufactured from the highest quality materials under strict quality controls.
Our windows feature tilting upper and lower sashes for ease of cleaning, low line beads and gaskets for improved sightlines, energy efficient glass to reduce heating bills, and, above all, they are quality assured for your peace of mind.
From a terraced house to a stately home, our vertical sliding sash windows ensure your property retains its character and charm. You can choose from a wide range of styles, colours and hardware options to complement your home perfectly.

Easy maintenance and cleaning
Your new windows will never rot, flake or peel. They will simply require an occasional wipe down with a damp cloth. The PVCu vertical sliding sash windows not only slide up and down but also tilt inwards enabling the panes to be easily accessed for cleaning from the inside.
Add a splash of colour
Choose from 9 standard colours
Safe and secure with a beautiful finish
Our vertical sliding sash windows are fully reinforced with galvanised steel. This strengthens the sash to prevent deflection in windy weather and provides a strong and secure fixing for handles, latches, and other components.
The high-quality balance mechanisms are used to maintain the equilibrium of the sash window at all points when traveling and robust locking devices ensure your home is locked up tight. For added security, an anti-jemmy aluminium bar is available. All of this gives you improved strength, greater safety and the reassurance that your windows are built to last.
