Original plan was to use Kingspan but current pricing is a bit ouch so I'm looking at building a 3 x 2 framework parallel to the full brick solid outside walls then filling the void with Rockwool (got a lot of timber and rockwool so those price hikes aren't a big worry). Question- am I ok with Rockwool in contact with the solid outside wall or do I need an air gap or VCL between rockwool and outside wall (there'll be VCL going on the face of the studwork anyway). Ta

I don't know the answer to your question, but in the extensions I've had built, the rockwool is in the cavity on its own. But, this is block, so maybe different ....
