Floor Soundproofing membrane D-FON

DFON is an impact noise reduction membrane supplies as a thin-layer that provides highly effective sound insulation for the reduction of impact noise. The membrane is applied under the concrete layer on the floor. Its sound insulating properties are guaranteed by the bitumen layer and the total thickness of the membrane is 3.4 mm. The material is waterproof and the installation is fast and easy. 

The sound insulation against impact noise is ΔLw = 26 dB.

Certificates:

EN ISO 140-1, EN ISO 140-3, EN ISO 140-6, EN ISO 140-8, EN 20140-2 and EN ISO 717/1/2, ISO: 9001

The installation is carried out directly on the slab under the concrete layer. The membrane must be placed with the bitumen layer upwards. Placed by overlapping the rows of at least 2 cm. It should not be fixed with nails or screws to the floor. A prerequisite for the installation is that the membrane must continue on the walls at least 10 cm. When installing the membrane and pouring the winding, the integrity of the membrane must not be impaired.

Required smear thickness 5 cm.

They can be placed under or over the heating pipes.
