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

NF = standard size, brick height 71 mm (3 inches) plus joint = twelve courses per meter (3.3 feet) wall height, DF = slim size, brick height 52 mm (2 inches) plus joint = sixteen courses. DF means one third more horizontal joints and one third more labor hours for the facing brick layer.
Additionally, with exposed or facing brickwork (in my opinion even with a random bond!), it is noticeable if the wall (section) lengths do not correspond to an eight-meter (26.2 feet) rhythm. Irregular measurements cause problems, especially when applying the facing layer. With easily sawable aerated concrete, this is not an issue if the rhythm is broken here and then restored in the facing layer. With other types of bricks, I would advise against wall thicknesses that do not conform to such modular dimensions. Ah, okay.
The number of labor hours required is relatively unimportant to us since we have already negotiated a price for this.
I just looked up slim size, but that would not suit us anyway. We prefer the classic standard size, as our house design is more traditional.
Thanks for the great explanation.
