Description
Insulated glazing (IG) also
known as double glazing are double or triple glass window panes
separated by an air or other gas filled space to reduce heat
transfer across a part of the building envelope.
Glass in windows is used to provide light and allow a view from
either side to the other side. While the composition and
manufacturing of glass is covered elsewhere, for the purposes of
this article, its importance to the construction is its dimensional
stability over a wide temperature range.
Insulated Glass Units (IGUs) are manufactured with glass in range
of thickness from 3 mm to *0 mm or more in special applications.
Laminated or tempered glass may also be used as part of the
construction. Most units are manufactured with the same thickness
of glass used on both panes but special applications such as
acoustic attenuation or security may require wide ranges of
thicknesses to be incorporated in the same unit.
To reduce shear effects on the sealed unit (a major cause of
premature failure), manufacturers use a rule of thumb that permits
a difference of 1 mm between panes of glass used in the unit and
still maintain the warranty for the unit. For example, a unit may
be ordered with a 4 mm pane on the exterior and a 3 mm pane on the
interior. These variations are allowed for architectural and cost
reasons. Other combinations can be specified and produced but the
manufacturer may reserve the right to limit the term of the
warranty or refuse to warranty the unit altogether.
