How do i remove glass from window for replacement?

I have what I think is aluminum windows. looking at the window it has 2 sections, the top half and bottom half, bottom half being the part you slide to open. each half has six sections, pieces of glass divided by strips. I need to replace one piece and cannot figure how to remove the damaged one. I have gone over all the edges with a “blade” to remove any seal but it still doesn’t budge. There are pieces on the exterior side that appear to “frame” the glass and possibly hold it in place, it doesn’t look like any form of putty, it looks like plastic. I need to find out what that is and If i need to remove it and should i be able to reuse it.

    Remove the plastic “frame” pieces first very carefully because you’ll have to re-use them or try to find new ones. They snap into a grove in the frame of the window. . Then look at the plastic that is between the six sections. Usually, the bottom is one piece of glass and the top is another. The plastic piece between the six sections is just a piece to make it look like 6 different pieces. Either way, you’ll have to remove it. It probably snaps in a groove. Then measure the glass to see what size you’ll need to purchase and go get the glass along with a tube of glass adhesive. Some people use clear silicon caulk, but if you do and you have to ever replace it again, you’re going to have a rough time getting the old glass out. Then the glass itself has a type of glue on it to seal it and hold it in place. So with gloves and eye protection, you need to remove the glass. If the glass is broken all the way to the edge, then it’s not to bad. If not, then it’s hard to get it out. I usually break the glass out from the inside to where i have smaller, easier to handle sized pieces. Remove all the glass and do a visual inspection to make sure there are no little pieces left sticking to the glue. Use your adhesive around the window frame where the glass is going to touch it. Press the new piece of glass into place. Then put the trim work back on. If you bend the “frame” molding slightly in the middle, it will go back into place fairly easy but be careful because if it’s pretty old, it will turn brittle.

    Cut a raw potato in half the glass should stick into the fleshy white part then you throw it away.

    Aluminum window have a “decorative” trim that actually hold the glass in place like putty used to of old wood windows. you will need to use a thin blade perhaps a sturdy razor knife to gently get between the trim & base of the window frame. Lift gently so you can get under it with the putty knife and work toward the corners and it should pop up. Replace your window applyong a thin bead of silicon first to secure the window and seal from heat/cold loss then snap the trim back in place. Not difficult at all.

    If the material is plastic the glass is secured one of two ways. 1- It may be a push-on strip. You can determine this by looking where the corners meet. If each pane has 4 strips you should be able to carefully pry them off with a thin putty knife. Plastic does get brittle after a while so go slowly. There also may be some glue between the stop and glass. You may have to slide a utility knife blade in this area to loosen.
    2- The plastic might be a u shaped channel that goes around on both sides. If this is the case, use the utility knife procedure but it may be impossible to get the new piece in.

    You need to pull out the entire window unit and take it down to the glass company. Look around for tiny screws. I have been doing household repairs professionally for over 30 years, and refuse to do an in home glass replacement on aluminum windows. That is one time when the extra $5 is cheap insurance.
