how can i replace glass pane in an alum window?

you should have glazing bead ( either plastic or aluminum) around the edge of the frame. between the glass and the metal. you can slip a putty knife between the plastic and the frame and pull it towards the inside of the glass. usually its "locked" into place. after pulling it away from the metal edge, you can slip your putty knife between the plastic & the glass and pull away from the window. if noone is there to help you, leave the top strip in so you can work on the other side. if they are aluminum strips holding the glass in, be VERY careful, as these are almost impossible to replace. measure your glass thats left in the opening before removing it. the old piece ( or what's left of it) is the best size you can use to order your new piece. call your local glass shop and ask for "single strength" glass. usually about 1/16" thick. after you pick up your glass and get home, then proceed to finish taking out your new piece.

you need to slip your putty knife between the old piece of glass and the window frame, on the opposite side of where you took off the glazing bead. there should have been silicone or some other sealant holding the glass in place. u need to cut that loose. you can sometimes wiggle the broken shards out pretty easily, depending on how long they've been in there. after taking out the glass, run your putty knife along the entire frame removing any shards left. wipe with a papertowel to clean completely. ( u can break the new piece with tiny pieces of the old one)

after cleaning the sash, u should use clear silicone on the frame. run a small bead all the way around where your glass will rest. place the new piece in the opening and replace the glazing bead. if you break any of the stops(glazing bead) u can usually purchase it at any glass shop. they'll get as close as they can. if they dont carry it, then silicone around the edge on both sides and it shouldnt leak.

good luck!!!

and go slow............ can get painful if not careful

if you dont have plastic or metal stops, youll have to putty glaze it. email me for instructions if you need them. :)

How To Replace Window Glass

Just about every possible answer has already been given. I would go with a replacement window as there is probably not enough room in your sills to replace a single pane with a double. Also would like to add that you should look into low e glass. The glass is coated on both panes on the inside to reflect energy out (the sun) and reflect energy in (heating or A/C) This is more economical and longer lasting that the older argon filled products. Argon will eventually leak out and become ineffective. It might also be noted that manufactures of argon filled only warranty their products for a short time, usually not even one year.

I agree with lilmissinsanity this is exactly what you need to do and how, being a window and door tech, and having done this more times than i care to count , lilmissinsanity No's her glass, if I were you I would wear gloves when removing&cleaning up the glass,and by the way the little pieces of glass you dont see are the ones that cutt you.

glazing bead is another term for glass stop,or the trim on the inside of the window. good luck,

Here's a good article. With single hung windows, the big issue is removing the moving pane, as every manufacturer has their own little tweak, and some are pretty poorly thought out. If you're replacing the fixed pane, then it's a much smaller headache.

Take out the frame and take it to a glass replacement center. Better than to try and fit the glass yourself. Ours cost less than ten dollars to have it done.

The stationary one is just held in by screws.
