GENERAL: are there Eurothane boards with sound insulating characteristics?
All insulation boards in the Eurothane/ Powerdeck range belong to the hard foam insulation board family based on PUR or PIR.
These are primarily thermal insulation boards and not directly intended to solve an acoustic problem.
However, in addition to hard foam Recticel also produces soft foams e.g. for use in the comfort sector. A number of products derived for construction have been developed from this such as Recphone and Recfoam. Recphone is recommended as an acoustic underlay carpet for loose parquet floors; Recfoam is an acoustic absorbing material for floors and walls.
