Hello everyone,

I am getting 36.5 Poroton as an exterior wall. My architect advises me to use Poroton for interior walls as well. However, he can't really justify the suggestion. But it would be cheaper. I was more inclined to go with sand-lime brick (no special dowels necessary, better sound insulation). What do you think? For Poroton or for sand-lime brick? Is sand-lime brick really more expensive?

It is said that different materials for interior and exterior walls cause cracks due to different expansion behaviors. It is also said that KS and aerated concrete can be used together, but Poroton is better if used alone. I have not checked this. What is cheaper probably depends on the region.

From the presence of Poroton

Because Poroton is comparatively soft and has thin internal webs, I would have concerns about hanging an 85-inch TV on a 17.5 cm interior wall. That makes special anchors necessary. With KS, I wouldn't worry about that.

Soundproofing can be accepted as an argument, but dowels? What do you want to hang on the wall anyway? Even if you actually need "special dowels," the quantities are not that large. By the way, an 85-inch TV does not weigh 50kg and is attached with more than one screw...
