Hello everyone,

We are planning our bungalow, and our architect has had good experiences with a Liapor construction. According to her, this building method is quite cost-effective and environmentally friendly. She would choose to build like this for herself.

I am not familiar with this building material personally, but it seems to be lightweight concrete with expanded clay aggregate. It sounds natural and promising at first.

I definitely do not want to use polystyrene insulation and, as a layperson, was considering T7/T8 blocks filled with perlite.

The plan is to achieve KfW 40+ energy standard.

However, I am just an amateur and would like to hear other opinions.

Thank you!

As far as I know, as @Nordlys wrote, for KfW 40 (+) the entire house must be considered. Only for KfW 55 is there an alternative verification option to meet minimum values for individual components.

Forget the mental image of a stuffed toy with its filling spilling out through a torn seam. Liapor is not a hollow block filled with popcorn-like material in its chambers, but rather a type of pumice stone—only made from clay instead of lava. Similarly, KLB, Bisotherm, and similar products are solid stone elements. Aside from the filling, pumice materials like expanded clay have a structure somewhat coarser than aerated concrete or cellular bricks, roughly analogous to the difference between Edam and Gouda cheese.

But it looks like a stuffed teddy bear.

A single brown brick with a rough surface.

The bottom edge is also open, so the item doesn’t arrive half-empty on site requiring the filling to be swept off the platform.
