Glass Replacement (Sliding Panes)

 

 

Sliding Vents with “Pound On Handles”  (Glass exposed on other sides)  For safety reasons, always wear gloves and safety eyewear when working with glass.  In general, it is recommended that this pane be replaced with a complete new vent assembly. The metal parts are not expensive and are often damaged in attempting to move them to another pane of glass.

REMOVING THE EXISTING OPENING PANE: Remove the screen assembly (see appropriate section in this manual. With the window closed, hook the exposed end of the two piece upper track and carefully pull it out of its groove. Work it loose and set it aside. The track is not symmetrical; note the orientation of the track in the groove.  Move the opening pane to the fully open position. Hook the other top track loose and carefully pull it out. With the top tracks removed, the vent pane can then be removed by lifting the pane upward and swinging the bottom out toward you.

REPLACING THE OPENING PANE: Reverse the procedure above: drop in the vent glass and slide to full open position.  Install shorter track above the open area, with the “pressure leg” of the track pushing the glass outward. Slide vent fully closed. Install the other track above the stationary pane. Test for easy sliding and locking.

 

SLIDING WINDOWS WITH PLASTIC “AUTOMOTIVE LOCKS:” (Glass exposed on other sides)

For safety reasons, always wear gloves and safety eyewear when working with glass. It is recommended that this pane be replaced with a complete new vent assembly.  Automotive locks require that the glass have holes drilled through it.  Most glass shops do not have this ability.

REMOVING THE EXISTING OPENING PANE:  Remove the screen assembly (refer to the appropriate section of this manual. With the window closed, hook the exposed end of the two piece upper track and carefully pull it out of its groove. Work it loose and set it aside. The track is not symmetrical; note the orientation of the track in the groove.  Move the opening pane to the fully open position. Hook the other top track loose and carefully pull it out. With the top tracks removed, the vent pane can then be removed by lifting the pane upward and swinging the bottom out toward you.

REPLACING THE OPENING PANE: Reverse the procedure above: drop in the vent glass and slide to full open position.  Install shorter track above the open area, with the “pressure leg” of the track pushing the glass outward. Slide vent fully closed. Install the other track above the stationary pane. Test for easy sliding and locking.

 

SLIDING WINDOWS WITH METAL FRAME SURROUNDING THE VENT PANE: For safety reasons, always wear gloves and safety eyewear when working with glass.

REMOVING THE EXISTING OPENING PANE:   Remove the screen assembly (refer to the appropriate section of this manual.)

REMOVING THE VENT GLASS:  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 can 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 types of bedding 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 vinyl.  Place the new glass into the prepared space, pressing down evenly on the glass edge.  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. Clean up.

 

SQUARE CORNERED SLIDING WINDOWS:

Removal of the vent: The sliding vent can be removed from the frame by sliding it to the full open position, raising it up into the top frame, and pulling out at the bottom.

Disassembly: 1- Measure the outside of the frame. The replacement glass (1/8th" thickness) must be 1 inch smaller in height and width than the vent assembly.  2- Remove the crews from the corners of the frame. Place a block of wood against the inner side of the frame and tap against the wood, starting near a corner.  Remove the side pieces in this manner.

Installing new glass: Replace the channel rubber on the new glass.  If damaged or unusable, order replacement rubber from Hehr.  Install the top and bottom frame pieces first.  Center them on the glass, then tap them gently on to the glass edge until they are firmly seated. The weatherstrip  must be facing the same side.  Install the remaining frame pieces. Screw the corners together.  Before reinstalling the vent section, check that it is square using a carpenter's square. If not square, gently tap a corner of the "long" dimension until the diagonal measurements are equal.
