ᐅ Which type of masonry is suitable for noise level category III?

Hello everyone,

I am new to this forum, so please excuse me if I forget something 🙂

My partner and I have purchased a plot of land, but it is located in noise level zone 3, which means we have certain soundproofing requirements for the exterior walls of the bedrooms.

Does anyone have experience with this and can advise us on which type of exterior masonry we need to comply with the DIN standard? We would like to use bricks because of the indoor climate. However, do we also need to consider additional insulation? How thick would the wall be in total? Or would it be better to use a different type of masonry block?

Thank you very much and best regards,
Pia und Eike

The best option is to use bricks filled with mineral wool. Thickness 42.5cm (17 inches).

Your planner will advise you on this.

P.S. The wall construction does not affect the indoor climate. Concrete, bricks, aerated concrete blocks, with or without full thermal insulation—there are no breathable walls that improve indoor climate. It would be better to consider, for example, clay plaster. That would be more than just a placebo.

We will also build according to LPB III standards. The masonry was not important for us; only the windows need to be considered.

Air-filled Poroton bricks without external thermal insulation composite systems (ETICS) are not recommended in areas with high noise exposure.

These bricks are ALWAYS not recommended. They are truly problematic in terms of sound insulation.
