Dungannon Window Company

Welcome to Dungannon Window Company LTD.
Home of the Eurosash PVC-U Sliding Sash.

Dungannon Window Company was established in 1987, we are specialists in our field, manufacturing the PVC-U Vertical Sliding Sash Window from 1995.  We supply our eurosash vertical sliding sash window solely to window trade customers throughout Ireland, Scotland, England, Wales and Isle of Man. Please feel free to contact us for your nearest installer.

We have devoted time and resources for over 20 years to manufacturing a high quality
PVC-U Sliding Sash Window.  As a market leader in it’s field, the eurosash window is the 1ST UPVC Sliding Sash Window in the UK and Ireland to achieve a 1.0 u-value, with a BFRC ‘A++’ energy rating.

Dungannon Window Company Limited recently installed the latest cutting and machining centre from Stuga, a new quad welder and the latest CNC corner cleaner from Sturtz.  All of which allows us to manufacture our VS efficiently and to a high standard.

The Eurosash Sliding Sash Window is designed to suit various styles of properties and comes with the widest choice of colours available on the market. The eurosash is versatile enough to compliment elegant period-style homes as well as modern dwellings and commercial properties. It has all the benefits of modern technology while still retaining the charm of traditional sash windows.

As a manufacturing company, we have a vast knowledge of standard PVC windows and doors, which we are able to manufacture to match all our foiled colours of sash windows, so we can supply a complete job, if the front and back of the house are different.

Recently we brought on the ‘Pure’ Aluminium System which allows us to manufacture lift & slide patio doors, bi-folding doors, resi doors and casement windows all in aluminium, again these items are of the highest quality and energy rating.

Feel free to browse around this site and learn about our eurosash and if you have any comments or questions about our products or services, or simply need more information, please contact us.
