How do these windows come out?

I have tilt out windows in my basement and I need to replace them. I have an 8" thick foundation wall and the frame of the window wraps around the concrete. How do I remove the frame? Here is a pic of the window. Thanks!

 

First, make sure that removing the metal frame is really what you want / need to do. Sometimes a new window can be sized to fit right into the metal frame without much fuss. In some cases, its preferable to leave the steel jamb in place since it's fairly level and square... whereas if you remove it you are left with a pretty rough cement opening. If the steel jamb is thin, you also may not gain much height and width by removing it. And in a few cases, the frame is semi-structural, like when you have cement blocks above the window and there is no other means of support (steel lintel). Judging by the picture, your blocks above the window look like they are supported by the steel jamb, so think carefully before you decide to go ripping it out.

If you deem that removing the frame is the way to go, a 4 1/2" grinder with a 1/16" cutting disk (for steel) is the way to go. You remove the operating sash, then you can usually make one cut through the middle of each side, then bend the frame around and get it to wiggle out. Occasionally you need to make 2 cuts (like through the head or sill) and remove a large section in order to free up the corners. The short side pieces are often the hardest ones to get out... but cutting them in half is the easy way to get them out without a lot of prying or beating which would damage the cement unnecessarily.

 

Ok thanks, the walls are pored concrete not block. The only reason I am asking is because I went into Menards to get a price on the windows and the guy said that the frame needs to come out. I frames are in good condition but I am finishing the basement and want insulated windows. I would also prefer sliding windows instead on tilting ones.

 

Since its a poured foundation, that sounds okay then. Just keep in mind that the concrete under the steel will be of unknown quality... and you probably do not have a sloped sill on bottom on the exterior side of the window, so you can't just assume you will be able to install a replacement window several inches back from the exterior face of the wall. Water has to shed to the outside on bottom. A window with a nailing fin would probably be best- they need to be installed on the outer edge of your cement wall. By the time you frame up a finished wall in front of the concrete one, that window is going to be a LOOOONG ways way from your interior wall surface. That will be the case with about any style window you get. Doubt they get opened that much anyway.

Sliders will have an exterior screen that will get full of grass clippings if they are close to the ground, just so you know. An awning window would be a good choice from the standpoint of having an easy to reach crank, and an interior screen.

And generally the guys at Menards don't know their head from their tail.

 

Ok thanks for the info! I guess I just need to do some research on what windows I want.
