When constructing curved glass block panels, Glass Block Technology recommend the use of a 10mm internal vertical joint. Using 190x190x80mm glass blocks, the minimum internal radius of 1650mm will result in the external vertical joint being 18-19mm. For other block sizes see GBT-0017 data sheet.

An example of curved screen in 190x90 half blocks:

• Radius = 900mm
• Internal vertical joint = 10mm
• External vertical joint = 18-19mm
• Horizontal joint = 10mm
