Overview Costs Properties Aerated Concrete Poroton Sand-lime Brick

Hello everyone, after much reading and comparing I haven't really become much wiser. I hope you can complete a table - with approximate values. Based on a solid house with a masonry wall for a Kfw55 requirement. I hope these variants have similar thermal insulation as well as soundproofing. Poroton 36.5 cm with filling Poroton 49 cm without filling Sand-lime brick 17.5 cm + 20 cm insulation Aerated concrete 36.5 cm What are the approximate costs per sqm for the different stones with possibly filling or insulation? Many thanks to you. Regards Bastian

I imagine it is difficult to answer that somewhat generally. Many aspects play a role for KFW 55, whereby the wall structure is only one partial aspect. Apart from that, there are different thermal conductivities for each of the wall variants mentioned above, e.g. aerated concrete 36.5 cm with lambda 0.10 - 0.07. The costs of these variants also differ greatly. So if one can create a table for that, it will have more than 4 rows/2 columns.

this is how it was with us... no idea if it helps you...

1 sqm sand-lime brick exterior wall manufacture 17.5 cm KS 20/2.0 including all cutting work = 37.62 euros

1 sqm sand-lime brick interior wall manufacture 11.5 cm KS 20/2.0 including all cutting work = 29.10 euros

1 sqm facade insulation board 14 cm, WLG 0.35 = 27.47 euros
