Hi,

what would you recommend for impact sound insulation under a laminate floor?

It should be a high-quality product that effectively reduces impact noise in the apartment below.

What options are available?

I found the "Silent CT" from Haro very impressive during the demonstration. These are thin adhesive strips on the underside of the laminate planks, which allow the laminate to be glued directly onto the screed. However, the laminate can no longer be easily removed afterwards.

Did you decide on the Silent CT impact sound insulation? How has your long-term experience been? I’m currently facing the same decision...

Hello, we ultimately decided on a "standard" impact sound insulation, about 3mm (0.12 inches) thick, dense, aluminum-laminated. It should work better with underfloor heating.

For a single-family house with a bedroom on the upper floor, impact sound insulation probably shouldn’t be overestimated anyway. At night, everyone is in bed, and even with the material we installed, airborne noise from doors, etc., is still more noticeable than impact noise.

We were repeatedly recommended the 1.8mm (0.07 inch) Parador impact sound insulation with integrated vapor barrier at several stores. It costs about 3-4€/m² (2in1 saves a work step by eliminating the need to install a separate vapor barrier, which is only necessary with new screed, otherwise it doesn’t matter according to suppliers).

Alternatively, there are also cork underlays (not ideal for underfloor heating because cork is insulating) or synthetic fabric underlays.

For the expansion joints between rooms, directly under the door leaf, spray cork was recommended. This material goes through all layers down to the screed.
