ACOUSTIC UNDERLAYS FOR SCREED


insulit 4+2

26-35 dB*

Ultra thin - Ultra efficient

The best price/performance ratio - NEW 2017

insulit 4+2 is an high efficient acoustic underlay intended to limit the transmission of impact and shock noises between different floors. Its low dynamic stiffness helps to reduce airborne noises too. It is put between the concrete floor and the floating screed approximately 5 cm thick.


acoustical underlay intended to limit the transmission of impact and shock noises

Double layer with pyramidal structure

insulit 4+2 is made up of a layer of closed-cells physically crosslinked polyolefin foam, glued on a low dynamic stiffness acoustic felt.
insulit 4+2 is thin, resistant and highly efficient; it’s available at a very attractive price. insulit 4+2 has been tested according to the European norms: EN ISO 717-2 and EN ISO 10140. This underlay meets all the criteria of the Belgian norm NBN S 01-400-1 in force for insulation between dwellings.
