Triple glazing adds a third pane of glass and a second gas-filled cavity to a window, cutting heat loss through the glass by around a third compared with A-rated double glazing and noticeably reducing outside noise. Hewitts Home Renovations supplies and fits triple glazed windows and doors in uPVC and aluminium frames across our five counties.
Triple glazing makes the most difference in north-facing rooms, bedrooms facing busy roads or railway lines, homes near flight paths, and new extensions or renovations aiming for the highest energy performance. It also virtually eliminates the cold-radiating feeling you get sitting near a double glazed window on a winter evening.
Our triple glazed units are 36mm or 44mm thick with two low-emissivity coatings, argon or krypton gas fill and warm-edge spacers, achieving an A++ Window Energy Rating. They are fitted in the same Liniar uPVC or thermally broken aluminium frames as our double glazing, so you can mix double and triple glazing around the house if you only want it in certain rooms.
Triple glazing costs around 15 to 25 per cent more than double glazing. We will always give you an honest view on whether it is worth it for your home rather than upselling it everywhere.

It depends on the room. For north-facing rooms, bedrooms on noisy roads and homes aiming for the lowest energy use, yes. For an average south-facing living room, A-rated double glazing is usually the better value. We will advise honestly.
Yes. The extra pane and cavity, especially with panes of different thicknesses, cut noise more than standard double glazing. For very noisy locations we can also specify acoustic laminated glass.
Yes, the units are heavier, which is why we fit them in reinforced frames with heavy-duty hinges. There is no difference in day-to-day use.
Yes. Many customers triple glaze bedrooms and north-facing rooms and double glaze the rest. The frames look identical from outside.
