Filled Poroton bricks vs aerated concrete

Why can't I screw anything onto Poroton bricks?

As far as I know, there's even more air inside and some Styrofoam in the middle, making it harder to anchor than in Ytong. Karsten

Thank you all. In this case, I will simply listen to the [GU] and build with the stone he recommends/suggests (that will probably be Ytong)!

As far as I know, there is still more room and in the middle there is some styrofoam, so doweling is harder than with Ytong. Karsten

Drilling without impact and using Fischer FIS-V also works for heavy items.

My point is. New construction. You order a kitchen from Küchenwunderwelt. which comes with a dishwasher free only today. Now Ali and Mehmed come to install it. Wall cabinets are of course included. The two are fearless, in a good mood and full of energy, they start drilling. Crumble crumble. Now dowels in, the slightly stingy boss only packs the Chinese ones in their case. It doesn't hold properly. Now, let's take thick screws.... first everything attached and hanging. .... Three months later and full of lady's fine plates, crunch and crash..... You full of anger, what bunglers... with Ytong this wouldn't have happened, the Chinese dowel works there too. K.

The normal Fischer S are completely sufficient, even in filled Poroton bricks. And inside is perlite, not Styrofoam.

Man, you really have to wonder that there are brick houses where wall cabinets get stuck...
