Combination of two STRUTO materials and heavy AMS (sandwich) to improve sound insulation. This variant is with a self-adhesive layer placed on the AMS. STRUTO is used as thermal and noise insulation such as motor noise insulation, hive insulation, acoustic door panels, 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, non-flammable, soundproofing, waterproofing rubber with high basis weight, high ductility and ductility.
