Hello everyone,
We are currently still comparing different construction companies:
- One company builds exclusively with Liapor.
- One company builds exclusively with bricks.
- One company builds with Ytong – the additional cost for bricks is 5,000€.
We are building a KfW55 single-family house with an air-to-water heat pump and a central ventilation system.
I am aware of the pros and cons of each building material, but I wanted to hear your opinions here, possibly also in connection with the ventilation system.
The company that uses Liapor is by far the most expensive, partly due to the building material. However, I really don’t see any added value that would justify the sometimes up to 10,000€ surcharge.
Right now, we are actually considering building with Ytong. We favor a company that uses Ytong as standard; as mentioned, the surcharge for bricks is 5,000€.
We prefer bricks, but the real question is: why? Will I even notice any difference afterward?
My cousin has lived in his Ytong house for four years and has never complained about sound insulation...
What are your thoughts?

The added value is likely related to the wall thickness, which the air-to-water heat pump may compensate for given the rather poor building envelope.
So, if the offered masonry thicknesses are the same, the lambda values should not be that significant. However, this should already be specified by the building permit / planning permission.
The building physics for brick are different because it is a composite material.

The small surcharge suggests that quite a few of their clients choose this option. If you are one of four clients who select it and believe it to be better, go for it; however, if you are one of twenty clients and the other 95% opt for the alternative building material, then it might be wiser for you to do the same.
