DAMTEC® resistant cork / resistant cork G



Flame-retardant acoustic underlay


Whenever the acoustic underlay must comply with high requirements of the structural fire protection (B1, Cfl-s1), then DAMTEC® resistant cork is the ideal acoustic underlay, suitable for residential and commercial buildings. With its special selection of raw materials, DAMTEC® resistant cork is of low flammability. It can be laid under parquetry and laminated floor, under textile floors as well as ceramic tiles. For the application under PVC and linoleum we recom-mend DAMTEC® resistant cork G, which is grinded on one side.


DAMTEC® resistant cork meets the requirements of German eco-label "Der Blaue Engel"
