Vertical sliding sash windows are a perfect combination of ingenious engineering and immense practicality. Replacing old sash windows usually means they have unfortunately come to the end of their life. Tired, draughty and lacking the required heat retention of thermally efficient windows. Our range of UPVC vertical sliding sash windows brings together the best of both worlds, a design that replicates the original look and features of the classic sash – right down to Georgian style horns and period brassware – with the precision fit, low maintenance and brilliant thermal performance of UPVC.
