Hi. My wife and I are currently having UPVC sash windows fitted across the whole first floor.
Having got four windows in place the installers have gone away to get architrave to cover the gaps, which are between 60mm and 80mm all around.
These seem like extremely large gaps to be filling and I wanted to know if this is common and if so how should we be expecting them to insulate that cavity.
Thanks for any advice.
