CLD 14 concists of a bitumen mat with self adhesive and paper release on both sides. Comes in 2 thicknesses; 1,4 mm and 2,1 mm. CLD sheets are primarly used for attenuation of radiation of structureborne noise in mechanical structures. Can be used in various applications with plywood, steel or aluminium base plates. Usually recommended for stiff structural applications, where unconstrained damping is unsufficient. Energy is dissipated as a result of shear deformation in the damping layer.
Material should have room temperature when cutting and during installation.
Light weight applications: Ventilation ducts, cabinets, noise enclusures, cabins.
Heavy duty applications: Bulkhead isolation, heavy constructions, thick steel panels. Wind-turbine generators, Marine & Offshore
