A 0.5-thick high density acoustic compressed foam is best suited for sub-flooring. Absorption panels prevent the penetration of sound through the floor, absorb low frequencies very well, excellently absorb footfall noise. They are used to improve the soundproofing properties of public cinemas, call centers, industrial halls and workshops, music clubs, auditoriums, music rehearsal rooms, dubbing and recording studios, living rooms and others. They are also suitable for insulation. They can be laid freely, glued with double-sided tape or contact adhesive.
