Understanding the differences between common glass types helps you choose the right product for every glazing job.
Toughened glass is heated to around 620°C then rapidly cooled, making it 4–5 times stronger than standard annealed glass. When it breaks, it shatters into small, blunt pieces rather than dangerous shards. It is required by Australian Standard AS 1288 in areas where human impact is likely — doors, sidelights, low-level panels, and wet areas such as shower screens. Common thicknesses for single-glazed toughened panels range from 4 mm to 12 mm.
Laminated glass consists of two or more sheets of glass bonded together with a polyvinyl butyral (PVB) interlayer, typically 0.38 mm thick. If the glass breaks, the interlayer holds the fragments in place, reducing injury risk and providing continued weather protection. It is commonly specified for overhead glazing, balustrades, and any application where fall-out protection is required. Popular laminate configurations include 6.38 mm (3/0.38/3), 10.38 mm (5/0.38/5), and 12.38 mm (6/0.38/6).
An Insulated Glass Unit (IGU) is made of two panes of glass separated by a sealed air or gas-filled spacer. The trapped air gap dramatically improves thermal insulation, reducing heat loss in winter and heat gain in summer. Double glazing also reduces noise transmission by up to 60%. Common IGU formats are described as glass/spacer/glass — for example, 6/12/6 means two 6 mm panes with a 12 mm spacer. The spacer width (8 mm, 12 mm, 16 mm) affects insulation but not glass weight.
Glass weighs approximately 2.5 kg per square metre for every 1 mm of thickness. A single 6 mm toughened panel therefore weighs about 15 kg/m². For laminated glass, the PVB interlayer adds negligible weight, so a 6.38 mm laminate is treated as roughly 15.2 kg/m². For double glazed units, the weight is the sum of both panes — a 6/12/6 IGU weighs approximately 30 kg/m². Knowing the weight is essential for selecting correct hardware, hinges, and ensuring safe manual handling on site.
