100mm mineral wool

Anyone used it? it's the only breathable system that I can source easily locally.

What do you do it you have high points? Can't rasp it back like EPS.

EPS is breathable
High point on mw needs to be filled out but if it’s a wet fix system it shouldn’t need much anyway.

use it alot.
contractors love it for the fire rating.

make sure you slurry coat the board before basecoat (wet on wet). gives a better bond
