Honest answers to the most common questions about uPVC sliding sash windows – from energy efficiency and soundproofing to customisation, installation and the difference between sash and casement.
A sash window features one or more moveable panels (the “sashes”) that slide vertically within the frame. Our modern uPVC sash windows replicate authentic Georgian and Victorian proportions while delivering today’s benefits: double glazing, smooth operation and low maintenance.
Yes. We make every unit to measure, so sash windows can replace most frames — including aging timber or standard casements. You’ll keep the classic look while gaining the durability, security and energy efficiency of modern uPVC.
Absolutely. All our sash windows include energy-efficient double glazing as standard to keep warmth in and noise out. For busy areas, ask about our optional acoustic glass upgrade.
Casement windows are hinged and open outwards; sash windows slide vertically within the frame. Both can be energy efficient, but sash windows are the go-to choice for heritage style and period properties where authentic sightlines matter.
uPVC needs far less maintenance than timber — no painting, no rot, no swelling — yet high-quality woodgrain finishes closely mimic real wood. You’ll enjoy excellent insulation, modern security and long lifespan with the look you love.
Yes. Choose from popular finishes like White, Anthracite Grey, Chartwell Green, Golden Oak and Rosewood, plus decorative and privacy glazing options and traditional hardware in matching finishes. Add Georgian or astragal bars to complete the heritage look.
