I've just had my kitchen window moved and fitted!!!
Now in the process of boarding out the internal surfaces.
All is complete bar the sill?? There is still the cavity exposed, what is the best solution to use here to fill cavity?
Expanding foam? However may all just drop down cavity....so loads will be required!!!
Pack it out??? Advice please so I can finish this job!!
There is no external cavity to rest the board on, so really need this cavity to be ridgid as poss!!!
