Jablite is cheaper, and probably adequate for a garage.

Just to be clear to the o/p though, it is an inferior product, requiring
5" to get the same insulating effect as 3" of Celotex or Kingspan.

Sure, but any insulation makes a big difference to a garage. I'd
probably go for 25mm celotex as a balance between price and loss of space

I think the objective is to improve the comfort level in the house by
insulating the wall between the garage and the house.

As you say, anything is better than nothing and it looks like the o/p
likes the cost of Jablite :-)
