Sealed units

Sealed Units Cut to Size

Our sealed units (also known as double or triple glazed units) are designed to trap a layer of air or inert gas between panes of glass, improving thermal insulation, reducing condensation, and cutting noise. All units are engineered for performance, longevity and clarity — while being fully custom to your specifications.
