Installation Instructions

The following instructions represent general and accepted industry practices for product installation. It is not the intention of Global Security Glazing to exclude or prohibit other installations techniques that are appropriate to specific building designs.

Global Security Glazing’s product must be installed in accordance with proper glazing techniques set forth in the Glass Association of North America (GANA) Glazing Manual and Sealant Manual 1990 (or most current edition). Clearance recommendations shown must be followed to protect all products from excessive pressure or glass-to-metal contact, which can cause breakage. Install setting blocks, not less than 4 inches long and slightly wider than the glazing at quarter points. Incorporate a weep system into exterior glazing systems. The installation of glass should be considered a finishing procedure. During glazing, product surfaces should be protected from paint, plaster, chemical splash or welding spatters. Polycarbonate surfaces exposed to direct sunlight must have masking removed and recovered with plastic poly/duct tape to the frames. Failure to do so may cause staining or shadows later.

Some PVC, EPDM, neoprene gasket, sealant and setting blocks are not compatible with Global Security Glazing products and can cause cloudiness and delamination. Please refer to Global Security Glazing Cleaning Instructions document for cleaning solutions compatible with glass and polycarbonate. Assume materials are not compatible unless approved by Global Security Glazing.
