Same price: Kfw55 with Poroton monol. OR Kfw40 with Poroton WDVS?

What the hell can be done to finally stop using this unfilled stone. I don't understand it. Everyone who has it is annoyed and would do it differently, and yet every 2 days someone comes along wanting to use it. No no and no again. Only filled. No matter how quiet you live.

Friday 9:00 pm, the first bottle is empty and the anger is already rising...

An acquaintance built with a T9 and we can sleep very well there, even though the night bus drives in front of his property and a café often throws parties until the early hours. What good is the filled Poroton if the windows, preferably floor-to-ceiling, only achieve a sound insulation value of 30dB?

I will throw another point into the room: do you have large window openings (larger than 2m) that need to be executed with concrete lintels? Then you do not have monolithic construction there anyway.

Axo. I'm still renting... last month... old building, solid brick. So the best sound insulation. Unfortunately, you can still hear the main street quite well because windows were unfortunately installed. That's how it is, unfortunately.

Yes, that's the next bad habit nowadays. Double-glazed windows have better sound insulation than the 30dB you mention. But the layperson thinks they have the good triple glazing without knowing that unfortunately this does not apply to sound. What's with the stupid allusion about the bottle? It's great and representative that you sleep well at your buddy's place twice a year. I sleep inside 365 days a year. So who can judge more accurately now? Today, the neighbor even approached me saying that he can hear the birds and it annoys him (Guru Guru) and I thought: wow, I'm not the only one annoyed by this. We both have this stone. And I don't have 30dB windows but 47dB.

What the hell can be done to finally stop using this unfilled stone. I don't understand that.

I already explained that last week:

Simply put, measures to dampen sound transmission (and sound reflection in the wall) have a dampening-reducing effect on heat transfer and vice versa.
