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. This thin underlay 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+.
Placing a single layer of insulit 55+ offers a cheap and efficient solution against impact noise while a double layer of insulit 55+ improves acoustic performance and increases safety during installation. The single layer brings an acoustic reduction of 22 dB and 24 dB if the underlay is placed in a double layer. Read further on the tests and results in the datasheet.
The 5mm underlay with a unique 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.
