Hello everyone,
various brick manufacturers offer their products with and without mineral wool insulation.
Both types of bricks have a thermal conductivity (λR) of 0.09 W/mK.
A disadvantage of bricks without insulation is the thin webs that may break easily if handled improperly. The possible drawback of bricks with integrated insulation could be the time factor. Who knows where the insulation will be in 20 years? It might degrade over time.
But what are the specific advantages and disadvantages in a single-family house?

In my opinion, you should keep your hands off the mouse …I recently asked myself the same question. Is it absolutely certain that the perlite filling or mineral wool filling will never degrade over the intended service life of a brick house (possibly 100 years or more) and that the insulation properties will never decline? Does the same apply, for example, to expanded polystyrene-filled lightweight aggregate/concrete blocks?
(I know this thread is old, but my question really fits well here).
Perlite filling is volcanic rock – have you ever seen a stone shrink?
I think you can forget the claim that the filling falls out when drilling into it. Nothing falls out at all. I have spent a lot of time studying this topic and have come to the conclusion that filled blocks offer significantly more advantages due to their better properties (sound insulation, thicker webs, etc.) and also significantly reduce the risk of plaster cracks. We will now switch to T9 instead of U9. If it’s KfW55 standard, then T8.

Okay, I looked into it: expanded perlite is heated to 1,000 degrees Celsius (1,832 degrees Fahrenheit), causing the stored water to evaporate and the perlite rock to expand. Afterwards, it needs to be treated with a hydrophobic coating, which prevents water from penetrating. If the waterproofing properties of this hydrophobic treatment eventually deteriorate, moisture could get in, which might cause the material to shrink (or not?), but at the very least reduce its insulation performance. It’s unclear to me to what extent these hydrophobic properties can be lost, but as we know, there is no coating (bitumen / waterproofing membrane) in basement construction that lasts forever. So theoretically, there is a possibility that the insulating properties could degrade over time. How relevant this is in practice???
We are waiting for the site development.
The notarial contract for the land was already completed last year, and the zoning plan was finalized recently, meeting our expectations. We have been researching kitchens and the options available nowadays. Additionally, we might build a basement, as the ground floor level is about 1.5 m (5 feet) above the terrain on one side.

Wasn’t the slope obvious enough to plan the basement from the start?
