BARRIER MATS

Applications
Barrier mats are frequently applied to vehicles, construction equipment, boats, lifts, floors, walls, enclosures, fans, ventilation systems, railway carriages, washing machines, sinks, doors and all vibrating sheet metal structures.

Use
The material is cut to parts of desired shape and size. Before installation, it is essential to carefully clean grease, dirt, dust and moisture from the base. The release paper covering of the self-adhesive backing is removed and the part is installed, starting from the shortest edge. The installation temperature should be between 15...40C.

We also produce tailored die cut mats to match customer drawings and material specifications.

Barrier mats
Our barrier mats can be used to control structure-borne noise propagation in solid materials and to improve their airborne sound insulation properties. In thin structures, applying a barrier mat directly to the surface of the material reduces structure-borne noise (vibration). In thick structures, the airborne sound resulting from the vibration of the structure is reduced with a two-layer mat in which a heavy layer is adhered to a foam layer.

In both cases mentioned above, the sound energy is converted to heat. The thinnest products of our diversified selection of barrier mats are made of bitumen board and the thickest of either EPDM or bitumen.
