Hi
I am building an extension to the rear of my house. The was a partial extension alreaady in place from the 70,s which only acted as an extension to my rear room. The new extension replaces the old one and also adds a new section to my kitchen.
Anyway, I knock down the old extension so that the brickwork would be new, across the whole of the new construction, rather than having new and old brickwork showing. In doing this, we removed the old extension and rebuilt it using the original footing. We continues the footing and cavity of the old extension into the new area.
We were unable to use cavity wall insulation as the cavity was too tight, so I need to insulate intenally. I was going to insulate using 30mm kingspan, dabbed to the internal blocks then cover with a 12mm plasterboard and skim. Would this be give me sufficient insulation resistance to satisfy the building regs. Or am I way off the ball.
Thanks in advance
