The ready made windows from B&Q or Wicks (can't remember which... maybe
both) come with some rather dodgy looking plastic tabs to clip on the
frame and screw on to opening leaving the glass in place during
install. It doesn't look like it would be a lot of fun fitting one of
those.
I fitted one of those from B&Q. The plastic tabs enable an OK fitting
(3 tabs on either side), then you fix with foam. I was only fitting a
smallish window so OK, but a large window, fitting with the glass would
be tricky - need 2 people. However, its probably harder to distort the
frame when fitting with the glass in.
