Aluminium Sash Windows

Managing the replacement of traditional Vertical Sliding Windows is difficult. Do you go with timber, this material clearly lends itself to lots of future maintenance. What about uPVC but do you really want so called plastic windows in your beautiful home. Aluminium offers a maintenance free option, that can achieve the quality appearance and usability of uPVC that will compliment your home.


We take great care to maintain that traditional Sash Window appearance. Our craftsmen meticulously assemble the cnc machined profiles of your windows, making sure the connections between the profiles are extremely tight. We can literally build any style of Sash Window out of aluminium that can be fabricated out of timber. By using aluminium there is the added benefit of colouring the windows with 65 microns of hard wearing powder coat. This coating won’t need any maintenance other than cleaning for many years to come, which has a massive cost saving benefit over timber sash windows.
