Glass Replacement (Torques, awnings & crank outs)

 

 

 

REPLACING  A SQUARE TORQUE VENTILATING PANE: For safety reasons, always use gloves and protective eyewear when working with glass.

REMOVING THE VENTILATING PANE: Crank the window fully open to give yourself working room.  The vent assembly is secured to the triangle shaped cast metal pivot brackets by two screws on each side.  Using a suitable Phillips head screwdriver, remove these screws, and free the vent assembly.

DISASSEMBLING THE VENT: Working on a flat surface, remove the four screws holding the vent together at  the corners.  Working from a corner, carefully work the aluminum frame off the vinyl u-channel which surrounds the glass.  These are lightweight pieces and are bent easily.  Be careful when removing them. Peel the vinyl u-channel off the edge of the glass. 

ASSEMBLING THE VENT WITH NEW GLASS:  Reverse the process above.  If the aluminum frame pieces do not push on with reasonable force, check to see that the replacement glass is not thicker than that previously used. If they are otherwise OK, try placing a small board on the backside of the aluminum and gently tapping it onto the glass with a  small mallet. Once the aluminum frame pieces are on the glass and square, replace the four frame screws.  Replace the vent assembly between the triangular pivot brackets  on the window and screw it on to the same screw holes. The top hole must always be used. Any of the lower holes may be used.  The lowest hole gives the tightest seal. After reassembly, we recommend recaulking all areas on the assembly which had been caulked previously, since disassembly has broken the caulk seal.

 

REPLACING A SQUARE TORQUE STATIONARY PANE: For safety reasons, always use gloves and protective eyewear when working with glass.

REMOVING THE STATIONARY PANE: The stationary pane is attached to the window frame with rivets.  Drill these out with a  power drill bit.

DISASSEMBLING THE STATIONARY PANE: Working on a flat surface, remove the four screws holding the assembly together at  the corners.  Working from a corner, carefully work the aluminum frame off the vinyl u-channel which surrounds the glass.  These are lightweight pieces and are bent easily.  Be careful when removing them. Peel the vinyl u-channel off the edge of the glass. 

ASSEMBLING THE STATIONARY WITH NEW GLASS:  Reverse the process above.  If the aluminum frame pieces do not push on with reasonable force, check to see that the replacement glass is not thicker than that previously used. If they are otherwise OK, try placing a small board on the backside of the aluminum and gently tapping it onto the glass with a  small mallet. Once the aluminum frame pieces are on the glass and square, replace the four frame screws.  At this time, recaulk all areas previously caulked, since disassembly has broken the caulk seal. Replace the stationary pane onto the front of the window, aligning the holes.  The frame may be resecured with  sheet metal screws or  pop rivets.

 

8700 & 7900: RADIUS CORNER TORQUE WINDOWS WITH METAL SURROUNDING THE GLASS: This window may be glazed with non-safety glass.  Use gloves and safety glasses when performing repairs, in case of accidental glass breakage.

 

REPLACING THE VENTILATING PANE  (SQUARE CORNER PANES)

 

REMOVING THE VENTILATING PANE: Crank the window fully open to give yourself working room.  The vent assembly is secured to the triangle shaped cast metal pivot brackets by two screws on each side.  Using a suitable Phillips head screwdriver, remove these screws, and free the vent assembly.

DISASSEMBLING THE VENT: Working on a flat surface, remove the four screws holding the vent together at  the corners.  Working from a corner, carefully work the aluminum frame off the vinyl u-channel which surrounds the glass.  These are lightweight pieces and are bent easily.  Be careful when removing them. Peel the vinyl u-channel off the edge of the glass. 

ASSEMBLING THE VENT WITH NEW GLASS:  Reverse the process above.  If the aluminum frame pieces do not push on with reasonable force, check to assure that the replacement glass is not thicker than that previously used. If they are otherwise OK, try placing a small board on the backside of the aluminum and gently tapping it onto the glass with a  small mallet. Once the aluminum frame pieces are on the glass and square, replace the four frame screws.  Replace the vent assembly between the triangular pivot brackets  on the window and screw it on to the same screw holes.

After reassembly, we recommend recaulking all areas on the assembly which had been caulked previously, since disassembly has broken the caulk seal.

 

REPLACING THE STATIONARY PANE: Carefully pry out the vinyl glazing bead by separating it from the frame with a putty knife. Once an end is loose, it can be pulled out.  Remove remaining pieces the same way.  If the glass is intact, carefully pry it loose from its bedding.  If the bedding is hard, it can be softened using an electric hair dryer. Since this glass may be non-safety, wear gloves and safety glasses while working with it. If there are glass spacers between the glass edge and the frame, set them aside for re-use. After the glass is out, clean the glazing ledge of the frame , so that the new glass will adhere evenly.

INSTALLING THE NEW GLASS:  Lay down an even bead of bedding on the glazing ledge.  There are many suitable, non-hardening beddings available from glass shops, auto supply houses, and home center stores. Do not use too thick a bead. It will have to compress in order to reinstall the glazing vinyls.  Place the new glass into the prepared space, pressing down evenly on the glass edge.  If space permits, slip your glass spacers in between the glass edge and the frame metal, across the bottom and up the sides of the pane.

 INSTALLING THE VINYL GLAZING BEAD:  This process will be easier if the bead is warm and moist. Soaking it in hot soapy water will work for this. Fit the bead snugly into the corner between the glass and frame.  Roll and push the bead backward into the groove, so that it does not stretch.  A round end plastic handle, such as on a screwdriver, can help to force the bead into place.  Apply all pieces the same way. Check to see that they are properly seated and clean up.

 

4800 RADIUS CORNER TORQUE WINDOWS WITH VENT GLASS EDGE EXPOSED: For safety reasons, always use gloves and protective eyewear when working with glass.

REPLACING THE VENTILATING GLASS:

REMOVAL OF THE VENTILATING PANE: Remove the screen and crank the window fully open for working room.  Using a suitable Phillips head screw driver, relieve the two screws at the ends of the  vent, and slide the pins to the center to disengage them from the backframe.  Using a small flat blade screwdriver or similar, remove the e-rings holding the triangular  pivot hinges to the tilt mechanism (be sure to support the glass, so it does not fall.)

REPLACING THE VENTILATING PANE: Reverse the procedure above.

REPLACING THE STATIONARY PANE: (Stationary panes above vent panes). Carefully pry out the curved vinyl glazing bead by separating it from the frame with a putty knife. Once an end is loose, it can be pulled out.  The straight side of the glass sits in a pocket in the horizontal mullion.  The other sides of the glass must be released before this side is taken out. If the glass is intact, carefully pry it loose from its bedding.  If the bedding is hard, it can be softened using an electric hair dryer. After the glass is loose, lift and pull it free of the mullion. Try to keep the thin vinyl glazing wedge in one piece for reuse. If there are glass spacers between the glass edge and the frame, set them aside for re-use. After the glass is out, clean the glazing ledge of the frame , so that the new glass will adhere evenly.

INSTALLING THE NEW GLASS:  Lay down an even bead of bedding on the glazing ledge.  There are many suitable, non-hardening beddings available from glass shops, auto supply houses, and home center stores. Do not use too thick a bead. It will have to compress in order to reinstall the glazing vinyls.  Place the new glass into the prepared space, pressing down evenly on the glass edge. Slide the glazing wedge between the glass and mullion so that it locks into place.

 INSTALLING THE VINYL GLAZING BEAD:  This process will be easier if the bead is warm and moist. Soaking it in hot soapy water will work for this. Fit the bead snugly into the corner between the glass and frame.  Roll and push the bead backward into the groove, so that it does not stretch.  A round end plastic handle, such as on a screwdriver, can help to force the bead into place.  Apply all pieces the same way. Check to see that they are properly seated and clean up.

 

REPLACE EXIT PANE IN A 4800 WINDOW

REMOVING THE EXIT PANEL: For safety reasons, always use gloves and protective eyewear when working with glass. Unlatch the exit panel and open it.  From outside, remove the hinge screws, using a suitable Phillips head screwdriver. Slide the exit panel horizontally out of the hinge.

REPLACING THE EXIT PANEL: Reverse the sequence above.
