Ultimate Noise Reduction:
Foam layer: The
DampTek® foam is a sound-absorbing foam with open cells. It is
fabricated on the bases of melamine synthetics and withstands
high temperatures and is flame-resistant. The DampTek® foam has
exceptional sound absorption properties. The foam layer
(combined with a barrier backing) is directed to the inside of
the computer case.

Barrier layer:
The DampTek® barrier layer is a flexible, sound-insulating
synthetic sheet made from thermoplastic, un-vulcanized rubbers
(EVA-copolymers) and mineral fillers. Its high relative mass
makes the DampTek® barrier layer an excellent isolator of the
noise in the PC. The barrier has a self-adhesive backing.
