Zealum ZN finish Alubutyl-insulating mat 78x46c self-adhesive

This innovative combination of aluminium butyl insulation mat as the base and a layer of acoustic foam as the top layer effectively reduces unwanted resonance from the outer door panel or door trim and eliminates sound reflections in the door for unmistakably more impressive bass reproduction. The aluminium layer provides additional stability, while the butyl significantly reduces the natural resonance of the panel to be insulated, e.g. the door panel.
