Hello everyone,
I want to build a solid masonry house.
The following materials are under consideration:
- Ytong (aerated concrete)
- Liapor (good insulation, but poor soundproofing)
- Brick
What are the advantages and disadvantages of each option?
Do I have a chance to achieve a KfW 55 standard?
I am willing to accept a wall thickness of up to 49cm (19 inches), but I do not want full thermal insulation on the exterior.
Thanks for your responses and tips...!

very interesting... could you also add information about sand-lime bricks?
Thank you

In case this question is actually serious: no, I don’t. I focus on everything related to new house construction; that’s already extensive enough. For left- or right-turning yogurt cultures, there are other specialists.
Kind regards

Do you have a source for the "propagation behavior of sound waves in lightweight expanded clay aggregate walls"?

Calcium Silicate Bricks
Calcium silicate bricks are made from a mixture of lime, sand, and water, which is pressed and cured without chemical additives. The curing temperature in this environmentally friendly production process is between 160 and 200°C (320 and 392°F). This relatively low temperature used for steam curing results in low energy consumption during manufacturing. No harmful substances are released. Therefore, calcium silicate bricks contribute significantly to energy savings and ecological balance.
Thermal Insulation:
The thermal insulation properties are poor. The thermal conductivity ranges from 0.5 to 1.3 W/mK, depending on the density.
Thermal Mass:
Due to the high thermal conductivity in exterior walls, additional thermal insulation is essential to meet energy saving regulations (building permit / planning permission). Highly insulated exterior wall constructions comply with the requirements of sustainable building practices.
Indoor Climate:
Calcium silicate bricks are available as solid, block, perforated, and hollow blocks in various sizes. They are suitable for both interior and exterior walls. The high breathability of calcium silicate bricks promotes a balanced indoor climate.
Building Biology:
This 100% natural building material has an excellent ecological profile.
Sound Insulation:
Calcium silicate bricks have a very high density, making them heavy. This provides excellent sound insulation properties. At the same time, they are highly compressive, allowing the construction of thin, load-bearing walls with very good soundproofing.
Fire Protection:
Calcium silicate masonry offers very good fire resistance.
All of this is also available on my website.
Kind regards

I still can’t help you; take a look at the Fraunhofer Institute’s website – I would be surprised if you don’t find what you’re looking for there.
Kind regards

I was absolutely serious about the inquiry. Your comments about the beads and the surrounding sound waves sounded very interesting.

ohneWissen9 Nov 2013 20:05We are also planning to build and have been at it for three years, only to realize that we cannot afford a solid timber house without glue, unless we build a small house without a basement.
It will be a bungalow without a basement, and I definitely do not want OSB boards or any PUR adhesives inside the house. Ideally, I would prefer a wall system made from just one material. While looking for alternatives to solid wood, I came across expanded clay (lightweight expanded clay aggregate) and Grundhaus. Unfortunately, I’m not very familiar with these options and would like to know:
Is insulation really necessary with expanded clay?
Is the indoor climate in an expanded clay house comparable to that of a solid wood house?
Compared to a solid wood house with Pavatex insulation and gravel beneath the floor, does it really save a lot of money? What kind of savings can we expect, assuming we build a bungalow with a pitched roof, 140m² (1507 ft²) of living space, triple glazing, and natural flooring?
Currently, according to our carpenter, we can afford a maximum of 108 to 110m² (1162 to 1184 ft²). But I see that just for planning and structural engineering calculations, instead of €2,900 we have to pay a hefty €5,700. Because of this, I assume we should have compared more carefully since prices don’t just differ slightly; they can vary by up to 50%. I tried to negotiate, but it was not possible, and the carpenter we want to work with only works with this architect. I personally don’t care about individual line items as long as the overall budget fits. But that’s exactly where the problem lies right now. We would like a few more square meters since we don’t have a basement, and that seems to be impossible with such a healthy building method.
I also had the idea of building the secondary rooms like the guest room, guest toilet, technical room, etc., with expanded clay, and the living and sleeping areas with wood. But as a layperson, I don’t know if that is technically feasible or if it would really save money to build an additional 20m² (215 ft²).
