Looking for triple glazing in Westminster? S&K Glazing has been installing across Greater London for over a decade. Triple glazing uses three panes of glass with two insulating cavities to deliver U-values as low as 0.6 W/m²K — outperforming standard double glazing by up to 50%.
Triple glazing uses three panes of glass with two insulating cavities to deliver U-values as low as 0.6 W/m²K — outperforming standard double glazing by up to 50%. Ideal for new-build homes, Passivhaus projects, and properties near airports, motorways and railway lines where extreme thermal or acoustic performance is required.
Westminster's mix of Georgian terraces, mansion blocks, and prestigious commercial premises requires a glazier with heritage credentials and commercial experience. We've worked across SW1, W1, W2 and WC2 on listed-building secondary glazing, shopfronts on Bond Street and Marylebone High Street, and acoustic upgrades for properties facing busy West End streets.
For window-replacement work in Westminster, the property mix across London ranges from period stock through to modern new-build, so we specify the thermal solution per property — A++ rated double-glazed sealed units for standard upgrades (U-value 1.4 W/m²K), A-rated solar-control glazing for south-facing elevations, and triple-glazed argon-filled builds achieving 0.8 W/m²K for owners targeting near-Passivhaus performance. Most commonly we're working across SW1, W1, W2 and WC2 postcodes.
Our technical team helps you choose glass thickness, gas filling (argon or krypton), and warm-edge spacers based on your performance targets.
Precise measurement at site, then made-to-measure manufacture using triple-sealed, gas-filled units from Pilkington or Saint-Gobain.
Triple glazed units are heavier and require specialist handling. Our FENSA-registered installers fit each unit with reinforced frames and structural sealants.
