Im in the process of renovating an old single storey barn (120 yrs) part of which is to be a double garage. The condition of the building is very good and is double skinned brick with 5 bay openings. For the double garage I want to line the existing wall at the back and gable end and a partition wall serparating the rest of the barn. I would like a nice neat block work enclosure as seen in many garages and wonder which type of block I need as they seem to vary in price and spec ie aerated, medium dense and dense. I intend to use wall ties to secure block wall against existing but I'd be grateful for any advice with regards any required insulation between the two. If required what sort would be suitable ie. kingspan or rock wool or can I lay them flush to the old brick.
Thanks in anticipation.
