Technical Bulletin 1006: IGU Installation
Australian Glass Group
The insulating and energy saving characteristics of Insulating Glass Units (IGU’s) are well documented, however their handling and installation require careful consideration, over and above those glazing methods often used for single glazed products. IGU’s can be manufactured in varying forms with a variety of seals and spacer materials. It is vital that these materials are compatible with glazing sealants and setting blocks used, and are glazed in such a manner to ensure they deliver the performance benefits over the life of the windows in which they feature. The airspace within an IGU is a hermetically sealed cavity (i.e. it is sealed away from outside atmosphere and environment). The perimeter seal of an IGU is the only protection the air space has against outside environmental factors. Framing systems which cater to single glazed window construction may need some modification to ensure that IGU’s are glazed in a way to allow maximum protection of these seals.
