Sonic felt 100 kg/m³, 9 mm thickness

Sound absorber for laying on horizontal and sloping surfaces.
Highly compacted acoustic felt for full-surface laying, or as underlay strips for acoustic decoupling between the subfloor and the structure
As edge strips for screeds.
Undyed, mottled yurt felt for the side wall and the roof.

IONIC PROTECT® biocide-free wool protection, long-term tested in accordance with EAD, using a trademark- and patent-protected process.
The protein molecules of the wool are modified by plasma treatment, so that for the entire service life they no longer provide food for wool pests.

Application: Lay the acoustic felt over the full surface of the wall area and fix it at the sides by stapling.
