Looking for triple glazing in London? 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%. For London properties near Heathrow, Gatwick, City, Luton, Stansted, we can specify acoustic-grade glass to reduce aircraft noise alongside thermal performance.
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.
London is our largest single market — 33 boroughs, five international airports, the M25 motorway and railway lines crossing every postcode. Our acoustic glazing dominates demand in flight-path postcodes near Heathrow (TW, UB, SW), Gatwick (RH, KT, CR) and City Airport (E16, E14). Plus commercial shopfront work across every high street and Zone 1-2 retail district.
For window-replacement work in London, 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 M25, E16 and E14 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.
