Hello everyone, we are currently planning our house and are unsure whether to choose Poroton brick walls or Liapor walls from the company NFC in Fulda.

I have read all the forum posts about Liapor. Overall, I am very impressed with the Liapor material and its properties (thermal insulation, soundproofing, etc.) as well as the fast construction method. My only concern is that I can’t find many experience reports related to this company.

Has anyone built with them and can share some insights?
Does anyone know someone who has built with NFC?

Since I am missing specific feedback about this provider, I am currently leaning towards Poroton 42.5mm (1.7 inches) with air chambers.

You can also send me a private message if you prefer.

Thank you all!

The topic of Liapor or expanded clay aggregate seems to have faded away. Is this construction method still up to date, or is anyone currently building with it?

Bloating aside, the FCN system walls are basically precast concrete elements. With all their advantages and disadvantages. I wouldn’t want walls where I need a Hilti for every hole, but as a timber house owner, it’s easy for me to say.

When it comes to thermal insulation, they can certainly perform just as well as solid brick walls, possibly with external thermal insulation composite systems (ETICS) if needed. Due to their mass, they likely have advantages in soundproofing, although this heavily depends on avoiding structural sound bridges. In this regard, the skill of the craftsman matters more than the quality of the component itself.

Ah, okay. Precast concrete elements seem to be going out of fashion, so I prefer to use Poroton instead.

@Rosthaus: Both lightweight expanded clay aggregate and aerated clay blocks are available as walls built directly on site or as fully prefabricated wall panels. Following trends is not a good guide when choosing wall material. There is no perfect solution, but it is best to use the material the builder is most familiar with, as this provides the highest chance of success.
