GENERAL GUIDELINES FOR THE INSTALLATION OF STEEL WINDOWS GLAZING FIRE RATED WINDOWS. DANGER! The glass used in a fire rated window must be UL Ô certified and labeled to match the UL Ô rating of the window. Any other glass used in a fire rated window will void the fire rating of the window and will put the building occupants in danger of severe injury or death in the event of a fire. Consult the window manufacturer for specific details on the type of glass for which the window was designed. Typically, the glazing beads in a fire rated window are made of steel and attached with screws. Fire rated windows usually ship with the glazing beads installed. Remove the glazing beads, marking the locations they came from so they can go back in the same locations. Clean the glazing rebate, making sure all dust, dirt and oil are removed. Apply glazing tape to the perimeter of the glazing rebate. Position the glazing tape down 1/8" from the edge of the section to leave room for the cap bead of sealant. The glazing tape should be compatible with the type of glass being used. Consult the window manufacturer for the size and type of glazing tape to use. Determine the size and locations for the glass setting & locating blocks to center the glass in the opening. Place setting and locating blocks in the appropriate locations depending on the type of window (see illustrations above). Remove the protective tape from the glazing tape. Insert the glass, centering it in the opening, and gently press it against the glazing tape. Replace the glazing beads, attaching them with the screws removed previously. Consult the window manufacturer for instructions about the sequence of installing glazing beads. If required, install the rubber-glazing gasket between the glass and the glazing beads. Apply a cap bead of silicone sealant to the outside surface of the glass where it meets the frame. A cap bead can also be applied to the inside surface of the glass where it meets the glazing bead. © The Steel Window Institute (2006) Contents are the property of the Steel Window Institute, its members or others who have licensed the information.
