This CRL Basic Insulating Glass Manual is specifically designed to help glass professionals become more familiar with the materials necessary for insulating glass fabrication. It takes you step by step through all methods of insulating glass production: Single-seal, dual-seal, silicone, butyl, and polysulfide. The GM12 shows you different glazing techniques, including glazing adapters for retrofit work. The manual also describes testing procedures you can use in your shop, and there is a section on insulating glass terms and definitions.
