Storage and Handling

FireVision IG fire-rated glass should be handled with care during transportation, storage, inspection, and installation. It should be stored in dry conditions only and needs to be stacked upright, at a slight angle. In addition, the glass panels must be separated by an appropriate material, such as soft pads made of cork, and the bottom edge must be supported along its entire length.


FireVision IG shall only be installed into fire-rated frame and window assemblies carrying the same rating. Each FireVision IG unit should be inspected carefully before installation, and any pieces with visible surface damage should be sorted out. All glazing components and the stop height must be chosen according to the appropriate UL classification. The glass panel must be placed on calcium silicate or hardwood setting blocks and glazed using appropriate glazing tape, such as closed cell PVC, Fiberfrax tape or Pemko FG3000S90. The installation of the framed unit must comply with the frame supplier’s instructions.


To maintain the aesthetics, it is important to keep the glass panel clean. A soft, clean, non-abrasive cloth and a mild soap, detergent, or non-abrasive glass cleaning solution is suitable for cleaning. After cleaning, rinse immediately with clean water and remove any excess water from the panel surface. Also, do not allow any metal or hard parts of the cleaning equipment to come in contact with the glass panel surface.
