Can anyone explain to me why windows are so expensive? (I'm talking about the glass ones, not the computer wotsits).
The double-glazing in the room I use as an office is well past its best and I decided to get some quotes. Granted, it's a big window but, *!*! me, 4,000 quid for some glass and some pre-built PVC that takes half a day to install? Is this normal?
