Installation Instructions

Installation Instructions


The following instructions represent general and accepted industry practices for glass product installation. It is not the intention of Curved Glass Creations to exclude or prohibit other installations techniques that are appropriate to specific building designs.
  • Curved Glass Creations 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 between glazing and framing materials must be provided to protect all products from excessive pressure or glass-to-metal contact, which can cause a break in the curved glass. 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 the glass should be considered a finishing procedure. During glazing, the glass product surfaces should be protected from paint, plaster, chemical splash or welding spatters.
Some PVC, EPDM, neoprene gasket, sealant, and setting blocks are not compatible with Curved Glass Creations products and can cause cloudiness and delamination of the curved glass products. The following materials have been found to be compatible with glass and polycarbonate for cleaning solutions:
  • Compatible Sealants, Gaskets, Tapes
  • Silicone: Dow 795, Dow 999, GE Silpruf, GE 1200
  • Gasket: Tremco Silicone (70D), Tremco EPDM (60,70D)
  • Tape: Tremco 440
  • Butyl Tape: KPTI 303, Isocryl 5600
