Combination of three STRUTO materials, heavy film AMS and aluminum (sandwich) to improve sound insulation. This variant is available on AMS with self-adhesive layer. STRUTO is used as thermal and noise insulation, eg as sound insulation of motor parts, hive insulation, sound filling in doors, and more. STRUTO is a non-woven thermally bonded fabric with perpendicularly laid fibers of secondary raw materials and polypropylene staple. AMS is ecologically and hygienically harmless, non-asphaltic, possibly flammable, soundproofing, waterproofing rubber with high basis weight and high ductility.
