Is additional impact sound insulation useful?

Hello everyone,

I have already read the installation instructions. The cork insulation just seems a bit "meager" to me. That’s why I was thinking about this massive impact sound insulation. If the standard one is also sufficient and gives a pleasant "sound," then that’s of course fine with me. I just didn’t want a laminate click-clack.

I also contacted Haro about this. I received an answer saying that you should not use a second underlay as stated in the instructions. Walking movements could occur that could damage the click connection.

That sounds plausible to me, but you can’t compare all underlays. This one is extremely massive and hardly gives way when walking (if at all). It’s not a 3mm foam underlay.

Cork remains dimensionally stable and does not shrink! For example, a 3mm foam underlayment usually doesn’t leave much behind, it tends to compress to half its thickness. The entire plank construction is not comparable to a loud, run-of-the-mill laminate; the plank system is designed in such a way that together with the cork, it provides excellent sound insulation. Of course, if you prefer, you can put another underlayment underneath, but the difference will not be noticeably felt. If there is underfloor heating underneath, that option is out anyway (just as a side note).

Ok thanks..I am installing it without any additional documentation. I think that will definitely be enough.

Hello,
a question from me. What is this "Disano" design floor made of? On the manufacturer's website it only says "DISANO by HARO is the ecological-sustainable alternative to vinyl floors: 100% PVC and plasticizer-free."

But unfortunately not what it actually is? Plastic? Vinyl? Linoleum? Wood? Cork?

Vinyl = PVC and therefore no Blue Angel because vinyl chloride is emitted... The top layer is not PVC but PE (polyethylene)... underneath it will be a wood-based material and then the cork underlay...

Hello,
I have installed click vinyl from b!Design along with underlay mats in several rooms since January and have been very satisfied ever since. However, the floor surface was somewhat uneven (old building), so the mat served its purpose and minor height differences were evened out.
