Aerated Concrete is Not the Same as Poroton

Hehe, yeah, my mind was elsewhere. But the question still stands.

Structurally, it wasn’t necessary, but I wanted it that way. a) for sound insulation, since my office is on the first floor, and b) for heat storage. I have an open kitchen/dining/living area with a masonry heater that is meant to gently warm the walls, and the more mass it has, the longer it retains heat. I’m attaching a picture of my floor plan where you can see this clearly.

Are there any negative experiences with Poroton? Our general contractor usually builds with it, and since he is specialized in this, we would prefer to stick with him.

An alternative supplier strongly advised against it. I’m not judging, as he works with calcium silicate blocks and wants to sell those, but he mentioned that, for example, you can’t properly drive a nail into the wall and that mounting things on the walls is very difficult. He also said it is essential to ensure that the workers do not throw cigarette butts or similar debris into the holes of the Poroton bricks and that no rainwater remains inside them.

Oh yes, especially "etc." should definitely not be embedded in the holes. For example, little notes with satanic verses—because those are loudly read aloud by tiny goblins on full-moon nights. Lord, give us some common sense from above; the things told about stones are ridiculous. The red color in the bricks comes from paprika, which is why you always have to sneeze in houses like that.

For every type of brick, you will find someone who says it’s devil’s work, useless, and should be banned.

That’s exactly what matters: the builder’s expertise with the material.

You can confidently place a Poroton house next to a Ytong neighbor’s house without any issues. They won’t clash. Limestone sand bricks are just different, but all these materials are perfectly suitable for building walls.

Sound insulation would be the most important factor for me when choosing the type of brick, and apparently calcium silicate brick is currently the "best." Clearly, an external thermal insulation composite system (ETICS) is needed, but that doesn't bother me.

I have Poroton bricks in the garage, and yes, it’s not that easy to install anchors in the wall. Anything that requires larger holes needs special anchors designed for Poroton.
