Nailing fins against siding or studs?
I'm ripping out an old window frame and installing a new one. The new one of course has nail fins that stick out an extra inch on all sides. The total width of this window frame including the nail fins is 31 1/2" (Minus the nail fins it's 29 1/2" wide). Currently the hole opening outside the house when the old window frame is ripped out is 30 1/4". So am I supposed to just nail the new frame against the siding of the house? The problem is that if I were to do this then the rest of the window will protrude 1 3/8". That seems odd to have to build a full 1 3/8" of siding to frame around the window frame sticking out that far. Should I instead cut out some of the house siding so that the nail fins sit inside against the studs?

Thanks. I kind of figured that was the case. So how would you approach this? I could cut out some exterior siding to make the window fit against the studs, however this is extra work, including patching it back up. I could also cut off the nail fins and I guess build some sort of support to hold the window in place. I should note that there are no side holes for nailing or screwing the window frame to the studs.

In instances where there is no sheathing on the studs and the siding *IS* the sheathing, current building practices indicate that the WRB be applied over the bare studs (before the siding is installed) then the window is installed on the WRB, and the top must be detailed correctly (behind the WRB) before the fin is sealed to the WRB with flashing tape... all of this prior to the installation of the siding.
Some guys will install on top of the siding when there is no sheathing, but that doesn't make it right.
If the house has sheathing, then the WRB is on top of the sheathing, and all other points (above) remain the same... as the only thing that has changed is the location of the WRB. The main thing is incorporating the new window into the WRB correctly.
If you don't have an existing WRB at all, that presents a problem.

Residential home with wood siding. See first post to see what I'm trying to do. Fit new window into hole when old window is taken out.
I measure the opening as 32.5" x 14" (that's concrete to concrete, concrete to wood). I'm looking at some replacement sliding windows from Menards which advertise dimensions of 31.75" x 14". Will the width dimension leave me enough space to work with?
Also, from my research, I should just be able to mount the window right into the existing concrete, correct? My plan is to use shims and tapcom screws to get the window set in place, then polyeurethane seal and foam to seal it up around all sides. Is there anything else I should be aware of?
Thanks in advance for any help.
