insulit 55+

The budget 5 mm underlay 22 - 24 dB


The cost-effective solution - NEW

insulit 55+ is an acoustic underlay which aims to reduce the impact sound transmission between the different floors of a building. A double layer of insulit 55+ is recommended and it has to be placed under a floating screed. Recent tests carried out by the BBRI in accordance with EN ISO 717-2 are proving the outstanding performances of the insulit 55+.


Our 5mm underlay with a pyramidal structure


insulit 55+ is made of a physically crosslinked polyolefin foam with closed microcells. The underlay’s ground-facing side is structured in a pyramidal shape to obtain a lower dynamic stiffness. insulit 55+ belongs to the “eco line” of our product assortment, which offers cost-friendly, widely renowned and highly qualitative solutions that have been developed by using state-of-the-art technologies.
