Neoprene Setting Blocks

Neoprene setting blocks from Quanex enable the isolation and elevation of insulating glass (IG) units from the sash. The neoprene material makes the blocks resilient, which allows for IG units to handle stressed conditions, and use of setting blocks helps to keep unit edges out of contact with any water that may be trapped in the glazing pocket.
