7 Newton Blocks

[staningrimsby]

Morning Guys,

I am building my small extension in 3.5 Newton blocks, but yesterday had 60 7 Newton blocks given to me, would it be best to use these on the outer skin or the inner skin, or doesn't it matter ???

use them on the outer skin if you wish. they are heavy, impossible to lay when wet and you can only course up about 4 courses at a time. difficult to muck-up too.

use a more thermally efficient block on the inside, i.e. lightweight or aerated.
