Insulated Glass Unit (IGU), various configurations (24mm, 26mm, 28mm, 32mm total unit)
Double-glazed sealed glass units with air or argon gas fill, providing thermal and acoustic insulation for windows and facades. Standard configurations from 24-32mm total thickness.
Double-glazed sealed glass units with air or argon gas fill, providing thermal and acoustic insulation for windows and facades. Standard configurations from 24-32mm total thickness.
Insulated Glass Units (IGUs) consist of two or more glass panes separated by a sealed airspace filled with air or inert gas (typically argon). The hermetic edge seal system uses primary polyisobutylene (PIB) sealant for moisture barrier and secondary polysulfide or silicone structural sealant. Standard Australian configurations include aluminium or warm-edge spacers with molecular sieve desiccant. Manufactured to AS 4666:2000 requirements with mandatory compliance for all Australian installations.
