ᐅ Aerated concrete blocks—Ytong, Solbet, or perhaps another type of concrete?

Hello dear building enthusiasts and experts,

We are planning to build a single-family house soon with an architect. The topic of house construction is so complex that after hours of research, sometimes you feel just as confused as before. Currently, we (mostly me, while my wife is already choosing decorations and wall colors) are focusing more on the structural shell and the suitable building material. Since the plot is in a fairly quiet location, soundproofing is of secondary importance.
Aerated concrete seems like a sensible solution, as this also rules out external insulation and interior plaster.
My question is: which aerated concrete manufacturer offers the best price/performance ratio? In our research, we keep coming across Ytong and Solbet, but are there other, less well-known companies that offer comparable blocks?

I would be grateful for any information.

Are you planning to do the masonry work yourself, or is there another reason you’re asking?
A shell builder who works with aerated concrete blocks will usually bring their own supplier. The building materials retailer, where you could get bricks for self-building, would do the same.

Why do you think you don’t need any interior plaster?

External wall insulation systems combined with calcium silicate brick / hollow bricks or aerated concrete don’t differ much in cost, depending on which material the shell builder uses more.

Masonry work by myself is not an option. However, as a client, I would make sure when awarding the contract that the most expensive brick is not necessarily chosen, but rather a good and affordable alternative.

Of course, a drywall finish cannot be completely avoided, but I would prefer a thin layer of gypsum plaster since I have limited space available anyway due to the tight floor area ratio.

You won’t be able to influence the manufacturer of the brick. Well, you can try, but that will just filter out the builders. The manufacturer doesn’t matter; what counts are the properties of the brick.

Gypsum plaster indoors is standard anyway, with lime-(gypsum) plaster more commonly used in bathrooms. You can expect about 1–1.5 cm (0.4–0.6 inches) of plaster on the wall.
Since you want to build monolithically, assume exterior walls to be around 36.5 cm (14.4 inches) of masonry plus plaster, totaling about 40 cm (15.7 inches) in thickness.

I understand your desire to be involved and to comprehend the subject, as I feel the same. However, you are choosing this path voluntarily. No one is forcing you to dive this deep.

Alex is right. Every masonry company has its own suppliers from whom they get their prices. As the end customer, you are mainly interested in the price including labor and adhesive.

Currently, it is said that people choose whichever supplier can deliver. There should be no quality difference.

An energy-saving regulation standard house with well-sealed windows and not too large glass areas can be built relatively affordably using 30cm (12 inches) blocks plus plastering, a gas boiler, and solar panels for domestic hot water. Karsten
