Hello all, I'm having some new softwood timber windows installed as I write. They are replacing some top-hung pvc windows (that I think replaced the original sash windows long before I moved in). If relevant, they are spiral balance rather than cords & weights.
Confused/slightly concerned about something. They are being installed brick-to-brick (there's a "reveal" which I guess is standard for sash in victorian properties?). From the outside, the gaps on the edges look pretty small. They filled (temporarily I assume for weather-proofing last night) with expanding foam.
On the INSIDE, however, there are huge gaps. Expanding foam again yesterday, and he's removing it at the moment.
One of the fitters (very nice bloke but a bit of a language barrier) said something about my frame being 45mm rather than 100mm which explains the gaps. Is this normal? I'm wondering whether it is and that large gap would be where the sash box would originally have sat? He said the gaps were the same before with pvc windows, and they were filled and then finished with wood trim.
Any comments or explanations would be much appreciated!
