Looking for triple glazing in Belfast? S&K Glazing has been installing across County Antrim 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.
Belfast's Victorian and Edwardian terraces, the modern Cathedral Quarter regeneration, and the post-Troubles commercial expansion drive glazing demand across BT1-BT17. Heritage sash restoration, commercial shopfronts, and large-volume re-glazing on the urban estates all feature in our Northern Ireland workload.
For window-replacement work in Belfast, the property mix across Northern Ireland 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 BT1 and BT17 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.
