Low Maintenance Design

If you're concerned about the up-keep of traditional sash windows then put your worries aside. A brand new UPVC sash window offers state of the art design and performance so you never have to worry about continuous painting or potential wood rot.

A perfect solution for a hectic lifestyle, our sash windows will never need painting or varnishing unlike previous timber frame designs. A simple wipe with a damp cloth every now and again is all these sash windows need to keep them looking beautiful throughout the year.

Sash Windows Colour Options

Upgrade from your standard white coloured profile to one of our exquisite foils, which we can add singly or in a dual format. We can also mix the foils to meet your design requirements.

Slender Sealed Units

Vertical Joints

For hundreds of years, traditional timber sash windows have been made with vertical joints known as mortice and tenoned. Contrary to standard uPVC windows, our sliding sash windows replicate this traditional method to achieve a truly authentic look.

Wood Grain Effect

To complete the authentic appearance of traditional timber sash windows, our uPVC profiles have realistic timber effect finishes in a variety of different colours. The illusion of timber is produced through a wood grain textured acrylic foil that covers the profile.

Features & Benefits

These stunning sash windows perfectly recreate the charm and character of traditional timber windows but offer the high performance of modern uPVC double glazing. Take advantage of the excellent security, energy efficiency, heat retention and weatherproofing.


Our uPVC sliding sash windows are manufactured to the highest standards, delivering enhanced security through a robust design. Steel reinforcements and design features that prevent leverage result in our sliding sash windows.


Our uPVC sliding sash windows have been rigorously tested for air permeability, watertightness and wind resistance, to exceed industry standards. Whatever the weather, your home will remain warm and cosy, without draughts or water ingress.
