Triple glazing is made in a similar way to double glazing but uses three panels of glass to create two airspaces. It provides excellent insulating performance but does have disadvantages.
- due to the extra thickness of the unit, they require an extra wide frame
- they let very little solar heat through
- the light transmission can be quite low due to the thickness of the three panels of glass
- in most cases retrofitting can not be done with triple glazing
There are a few products now available that are more efficient than triple glazing, for both cost and performance. These are 'coatings' applied to the glass during manufacturing called Low Emissivity Glass (Low E glass).
See our Low E Glass info page for me details.
Technical specifications, including U values and light transmission details are available from us.
