ᐅ No construction company can be found that...

Hello,

Our search for a turnkey construction company in the greater Cologne area has proven to be very difficult. It’s not that there are no providers, but those we have found so far do not meet our expectations and do not deviate from their standard services.

The main issue is that all of them work exclusively with aerated concrete blocks.
However, we want a traditional wall made of calcium silicate bricks + insulation + facing bricks.
The reasons are sound insulation, the practical handling of hanging objects, and indoor climate.
Can anyone recommend a company for postal code area 50 that also builds with calcium silicate bricks and offers custom planning?

THANK YOU

You can contact me; we offer custom planning and can also build your house using calcium silicate blocks.

...what does "attached to it" mean? You hardly find any problems reported with calcium silicate bricks, but horror stories about aerated concrete. I want to spare us that...
For the past two weeks, I have been focused solely on wall constructions... and somehow it all goes around in circles. One says this, another says that... but who am I kidding here 🙄

Sand-lime brick provides excellent sound insulation but has poor thermal insulation properties – so you definitely need additional insulation.

The "horror stories" on the internet regarding aerated concrete are mostly fabricated, if not spread by competitors; I know quite a few of these and can refute them all, as they belong to the realm of myths. Since you plan to build a cavity wall anyway, it really does not matter which brick forms the inner leaf, because the insulation and the outer brick veneer will compensate for the negative aspects 😉

There is no all-in-one solution; you won’t find it even with sand-lime bricks. Every type of brick has advantages and disadvantages, and overall it always depends on the complete design concept.

Well, if there were an aerated concrete block that, with a normal interior wall thickness, would prevent me from overhearing the toilet use in the next room or allow for proper wall mounting, then I might reconsider. Also, sand-lime brick offers good thermal storage properties and tends to have a cooling effect in summer. Aerated concrete doesn’t have either of these qualities, or correct me if I’m wrong, and it also has issues with moisture...

Please just share your choice without any specific discussion or bias:

1. Sand-lime brick 24cm (9.5 inches) + 12cm (5 inches) insulation + facing brick
2. Aerated concrete 24cm (9.5 inches) + 12cm (5 inches) insulation + facing brick

Oh dear… now we’re going in circles again… 😉

P.S. Interior walls are made of either 17.5 cm (7 inches) calcium silicate blocks or 24 cm (9.5 inches) aerated concrete blocks...
