Accidents happen and broken windows may be the result. When you go to replace the glass, you may realize that the window has an aluminum frame. These frames may look intimidating since there appears to be no way to replace the glass, but in reality it is quite simple. Most manufactured aluminum frame windows come in several pieces -- the glass, a silicone seal (glass sealant, glass silicone, glass glue)and the four aluminum pieces that make up the frame. Four screws at each corner hold the frame pieces together. Find and remove these screws to remove the glass pane from the window frame.
Remove the frame from the window to make the replacement process easier and safer. Lift up the sliding aluminum pane to remove from the window frame. Remove screw fasteners in fixed panes with a screwdriver before sliding out of the frame.
Locate the screw fasteners at each corner that hold the four-piece frame together. Remove each screw with a screwdriver and pull each piece from the broken window. Pry any stuck frame pieces off using the slotted end of the screwdriver. Be careful to not bend the frame pieces when pulling or prying.
Pull the silicone seal that surrounds the outside edge of the broken glass off to reuse; you'll need a replacement if the seal is broken or torn. Scrape away any leftover seal residue with the flat end of the slotted screwdriver.
Place the new piece of glass on a flat work surface, a work bench, or a built-up work area with the help of saw horses. Slide the old, or new, silicone seal around the outer edge of the glass making sure it is tight with no bubbles or lose portions.
Slide each aluminum frame piece onto the outside edge of the glass, making sure they are installed in the same fashion as before the old glass was removed. Tap the aluminum frame over the glass gently with a mallet.
Butt up each aluminum corner so they are flush and thread in each screw using the screwdriver, working around the entire window until the frame is secured. Inspect the entire outside edge of the newly constructed glass window. Make sure the seal is flush to the frame; push it gently by hand or with the slotted screwdriver if it is not.
Reset the window pane into the frame in the reverse fashion that it was removed to complete the glass installation process.
