STP Bromo — combined sandwich material with sound absorption and sound insulation functions. The open-cell structure of the soft layer effectively disperses sound and reduces its amplitude. The heavy sound-shielding membrane reflects penetrating sound waves and does not pass them into the interior space of the car. The face coating with contrast printing allows easy differentiation of the
STP Bromo from other materials and makes cutting the material safer for the installer. Combining several functions in one material and compact mini-format speeds up the mounting process.

The STP Bromo a sound insulation test for processing the second layer, on top of the sheet of the Vibrodamper. The material is suitable for application on the floor in the cabin and trunk, as well as on the rear wheel arches from the side of the cabin.
