Double Glazed Windows vs Sealed Glass Units

Double glazing is quite a niche subject at the best of times, with lots of terms to get your head around. What are sealed glass units and how is that different from a double glazed window?

Double Glazed Window

When we talk about double glazing, we usually mean the full window. This includes the glass, the frame and everything that goes into windows. Our 10-year guarantees refer to the frame, covering parts and labour.

Sealed Glass Unit

When we say sealed glazed unit, we mean the glass in the frame. This consists of a spacer bar, two glass panels, the void between filled with inert gas and an airtight seal around the edge. This unit goes into the frame and makes up a double glazed window.
