Triple Glazed Units

Triple glazed units add a third pane of glass and a second gas-filled cavity to the standard double glazed build-up, cutting heat loss through the window still further and adding a second layer of sound-deadening air space at the same time. The trade-off is a slightly thicker, heavier unit, so we check your frame's glazing rebate can take the extra depth before quoting.

It's the specification we recommend for north-facing elevations, rooms that struggle to hold heat, or homes running on air-source heat pumps and electric heating, where every extra degree of retained warmth counts.
