FOUR S1-MultiBase – Sound Deadening Mat 500 × 370 × 7.5 mm 1.48M2

FOUR S1-MultiBase is a high-performance multi-layer sound insulation solution designed for easy sound damping. The mat consists of two layers: a 6 mm thick foam rubber layer at the bottom, topped with a 1.5 mm heavy fabric mat. This combination effectively dampens both low and high frequencies.

Thanks to its flexible structure, S1-MultiBase easily conforms to curves and contours, ensuring quick and tidy installation. For more effective damping, we recommend installing S1-MultiBase on top of an alu-butyl mat — this provides highly effective damping and eliminates resonances from sheet metal and panels.

The bottom layer of the mat does not absorb water, making it suitable for doors, floors, wheel arches, trunks, etc.
