Windows for roof raise

Hello everyone,
I have some basic roof raise window questions. I have looked around and not found complete beginner answers. If I am going to raise the roof and replace the windows am I essentially just securing in sheet metal and then placing the window within the cut? How am I securing the window to the steel? Are there typically holes or trim material that allows you to affix it? Besides junkyards has anyone found any good places to acquire windows? Last question what is the technical name for the Column which holds the window in( the channel that is being cut)? I know itís basic stuff but I appreciate the help.

Yes, you are basically removing the windows, skinning the sides and cut in the new windows. RV windows normally have a trim ring on the inside that sandwiches the window to the wall. I prefer to add steel tubing to frame the new windows and not hang them just on sheet metal.
I've had good luck sourcing windows and other RV parts from this eBay seller"

the roof raise entails removing widows cutting hat channels they are spaced about 2 ft apart depending on MFGR lifting roof welding or bolting in fillers some folks used custom hat channels I used 1 1/4 " tubing on mine then I cut openings where needed framed the openings with 1 1/4" tubing skinned the sides cut the openings to fit the windows butyl taped the windows and riveted them to the 1 1/4" framing I can't imagine attaching them just to the sheet metal as wind whip and vibration surely would be their demise also if you insulate the sides of your bus unless you buy custom windows the supplie trim rings will be of no value as the walls will be to thick.

Poor planning cutting the hole, should have cut the radius in the corners. Now there's 4 repairs to make.

That opening looks like a dangerous loss of structural integrity, thanks to the two cut (and removed) hat channels and no sort of header above the window to compensate. And it's right behind the driver's seat.

It is all framed in 1' tube and bars where the hat channels were removed. If it were me, I would have run the horizontals out to the next set of channels. That's a long window and surely less structural integrity, but enough to worry about, nobody knows.

Removing a rib or two isn't the end of the world.
