I'm looking at cladding the outside of a new house with some kind of lightweight cladding that can give a rendered look. Of course there's blueboard, but I've also see some houses going up with a light aqua-green panel which looks to be a lot thicker than the blueboard fc sheets. If anyone know's what this is or can provide other suggestions then I'd be grateful. I've also thought about Hebel but it's too heavy for my purposes.
I'm worried about getting a good quality finish on the blueboard becasue I'll be using a timber frame with no eaves, so the sun sun will at times glance the wall surface and bring out any warping or poor finishing - is this something to worry about?
