STP STPSNORA Sonora Special Line 5mm Vibration-Damping & Sound-Proofing Material

Quick & Professional Installation Process, With Better Overall Results!

STP Sonora Special Line
STP Sonora (Order Code STPSNORA) is a new-generation material for car sound insulation. It is intended, first of all, to treat the inner space of doors with a second layer - an area where moisture is regularly present. The material effectively resists moisture due to the non-hygroscopicity of the soft polypropylene foam layer and the increased adhesion of the mastic adhesive layer. In addition, a dense soundproofing membrane complements the effect of isolating the interior from external noise. Sonora uses layer-combining technology, which reduces the application time. StP Sonora includes 10 sheets that are 750 x 470mm in size, 5.2mm thick, providing a total coverage area of 3.52m2.
