uPVC sliding sash windows combine the elegance of traditional vertical sliders with the advantages of modern materials. Ideal for period homes in Hampshire, character properties in Portsmouth, or townhouses in Southampton, they retain the classic proportions and detailing associated with heritage sash windows while offering improved practicality.
Unlike original timber sashes, modern uPVC versions provide smooth sliding operation, enhanced insulation, and long-lasting reliability. You can enjoy the charm of a traditional sash window without the maintenance demands often linked to older designs.
