Stainless steel ribbed reinforcement rods are used to anchor glass block panels in place and increase integral strength. The rods should be at least 5.5mm diameter and a minimum of one stainless steel rod should be used within each horizontal and vertical course.

Where reinforcement rods are joined, allow a minimum overlap of 150mm and loosely tie using tie wire.

Reinforcement rods should be anchored into all substrata's to a minimum depth of 25mm. An over sized hole should be drilled, then filled with silicon to allow the reinforcement bars to move with expansion and contraction. For reinforcement with U channels refer to data sheet GBT-0003.

Reinforcement rods should never rest on or be in direct contact with any of the glass blocks. Spacer pegs have a cross section where the rods can be positioned onto.
