What is the best way to insulate a Multi-material wall?
...insulation against poured concrete walls+concrete blocks+bricks, all part of the same wall assembly?
As the bricks that sit atop the concrete walls are uneven (along the grout and brick face), would it be best to apply a skim coat of mortar, like Type S to parge and even the surfaces, then add my EPS?
I am planning on ...
