Enhance your installations with stylish UPVC vertical sliding sash windows

The UK has the oldest housing stock in Europe, with around 20% of houses built before 1919 according to an extensive study by the BRE. Many of these houses originally featured timber sliding sash windows, meaning there’s a huge sales opportunity for installers like you to restore these homes to their former glory with a modern alternative.

Our uPVC vertical sliding sash windows are manufactured using Charisma – the purpose-built VS profile system from our partners Eurocell. Charisma uPVC vertical sliding sash windows replicate the look of timber without common problems that these windows bring – such as high maintenance, cold draughts, and security issues – giving consumers the best of both worlds.

Our uPVC vertical sliding sash windows are renowned for their smooth gliding, impeccable functionality and have built-in anti-jemmy bars and hardware that is fixed directly to reinforcement for optimum security. Available in a wide range of colour options and finishes, they can complement any property.
