Vertical Sliding Windows

Sliding sash windows are synonymous with period properties. They are an integral feature of Georgian, Victorian, and early twentieth century homes. Many period properties still have their original timber windows. These may have failed and are no longer safe or efficient. Fortunately, there is a modern alternative.

uPVC sash windows in Bath, Bristol, Wiltshire and Gloucestershire

At Techniglaze, we install uPVC wood effect sash windows from the Rose Collection. The three suites of windows: Ultimate, Heritage, and Charisma Rose have all the period detailing of traditional timber windows with all the benefits of modern uPVC. The Ultimate and Heritage Rose are so authentic that they are regularly approved for use in conservation areas across the UK. We also install aluminium sash windows from Smarts. The Smart VS 600 combines the traditional style and opening function of a vertical sliding sash window with the modern performance of an aluminium profile.

    Techniglaze uPVC vertical sliding windows can be finished in a selection of durable woodgrain foils. Choose popular White or Anthracite Grey for a modern and understated aesthetic. For a more traditional look, opt for a realistic timber inspired finish. If you want a different look on the interior and exterior of your windows, we offer dual coloured windows for the best in customisation. For our aluminium vertical sliding windows, choose from any RAL colour for their weather resistant powder coat finish.
