Afternoon,
Well just as I thought id got my head around cavities and insulation I’m now not sure I have
I was under the impression that a cavity was a standard 100mm but I’ve just read that refs have changed and now it’s 150mm ? Is this right or have I miss read it ?
If it’s still 100mm standard can this be reduced to 900mm?
Basically we are planning on putting a bay window in on a dwarf wall prob starting in April when we have pp … 900mm would be perfect 150mm will cause me huge issue!
Thanks
Jake
