Balustrade Glass Types Available - SG12 Frameless system
Which glass options are available with our Hybrid® Balustrade system?
The SG12 has two glass thicknesses that are used, one for residential applications and one for public applications, residential applications use 21.5mm thick glass (10mm toughened + 1.5mm interlayer + 10mm toughened) whilst public applications use 25.5mm thick glass (12mm toughened + 1.5mm interlayer + 12mm toughened)
Residential applications glass options for SG12:
- 21.5mm clear laminated & toughened (with or without BalcoNano® coating)
- 21.5mm opaque laminated & toughened (with or without BalcoNano® coating)
- 21.5mm Low-Iron laminated & toughened (with or without BalcoNano® coating)
Public applications glass options for SG12:
- 25.5mm clear laminated & toughened (with or without BalcoNano® coating)
- 25.5mm opaque laminated & toughened (with or without BalcoNano® coating)
- 25.5mm Low-Iron laminated & toughened (with or without BalcoNano® coating)

A short explaination what is "Low iron glass"
Even though what we refer to as regular "clear" glass, does not have substantially high iron content, it is higher than low-iron glass. Due to this higher iron content, clear glass has a greenish tint. This is a result of the natural presence of iron oxide from elements such as sand, or from the cask or container in which the glass was actually melted.
Float glass manufacturers create "Low-iron" glass, also known as "extra-clear glass" or "optically clear glass", by reducing the amount of iron in the molten glass formula. This type is more transparent than regular glass, and doesn't have that greenish tint. In fact, modifying the iron content can increase the light transparency by 5 to 6 percent.
