ᐅ Self-adhesive impact sound insulation

Hello,

We want to install luxury vinyl flooring in a large part of the house. We have chosen glued vinyl because the desired appearance was not available in a click-lock format.
Now the question arises regarding the installation.
Usually, the new screed needs to be primed, filled, sanded, and then primed again.

I have come across self-adhesive acoustic underlay materials (e.g., Planeo) online.
As I understand it, the substrate does not require further preparation with these, which can save a lot of work.

Does anyone have experience with this type of acoustic underlay?

Thank you!

Hi,

Did you install the adhesive version? We are facing the same question. We have a quote for the adhesive method (around €9,500) and now I’m considering whether I could manage it myself with the membrane. Then it would only be the cost of materials and the rest could be done on our own.
In my opinion, there are two different membranes. One that is just unrolled (floating) and adhered only on top. And another that sticks both on the top and the bottom. Maybe someone with experience can share some insights!?

Hello questioner.
As I understand it, you do not want a flooring system as a module, meaning no floating installation with lateral locking of the elements, but another option.
However, there are only two options: either loose laying or bonding with a properly prepared subfloor!
So, if you do not want loose laying (because the market did not offer the desired design), the only remaining choice is full-surface adhesion.
In that case, a so-called "impact sound insulation underlay" should not be used, unless it is integrated into the installation system.
An elastic floor covering, including plank-shaped cuts, naturally changes its length as an elastomer under climatic variations.
That means: if sunlight falls on the surface, or even just the unavoidable temperature differences over the course of a year, the flooring requires a “firm hold” so that it cannot move uncontrolled.
With an underlay foil, this is simply not achievable, as the adhesive bond between the layers will not allow it!
Furthermore:
No new screed has the surface properties to be used immediately as a substrate for floor covering installation (except for ceramic tiles and solid wood parquet)!
This means that leveling compound is an important factor in achieving even absorbency (for the water in the adhesive) and to smooth out the roughness of the screed surface.
So you do not save anything by choosing an installation method that is not at all compliant with professional standards.
Instead, you are heading for total failure of the flooring layer, which will require renovation.
I suppose there is no need to elaborate here on the cost aspect and proportionality?
---------------------------------------
But the choice is yours. I can only offer advice to avoid potential damage risks recognizable to me in this forum.

Thank you for your detailed response. I’m not referring to the standard impact sound insulation, but to the membranes that have an adhesive layer on the top side. These were apparently developed specifically for vinyl planks.

The floor won’t be installed until December, so I still have some time.

This means no preparation of the substrate would be necessary. The membrane is cut to size, laid out, and then the planks are glued onto the membrane. It is an intermediate solution.
I had inserted a link to the product, which was removed for understandable reasons.
I’m not sure if I’m allowed to write the name here.

I know the membrane from Plan...eo. It is actually similar to a full-surface adhesive membrane. Both the underside and the top side have a self-adhesive layer. Whether and how well it works, I don’t know.
