Component Layers

Recommended Uses

Adhesive

Absorber

Facing

Used to line the inside of cabinets, compartments and panels where the existing skin provides the necessary transmission loss.  Increasing the thickness and/or density increases low frequency acoustical absorption.

Adhesive

Damping

Absorber

Facing

Used to line the inside of cabinets, compartments and panels where it is necessary to add mass to the existing skin, reduce structural resonance and absorb airborne sound.  The absorber layer faces the noise source.

Adhesive

Absorber

Barrier

Used to line the outside surfaces of equipment housings, connected ducts, pipes and other guards and panels where inside surfaces are not practical to treat.  The absorber layer acts as a decoupler/spacer to enhance the transmission loss of the barrier.

Adhesive

Absorber

Barrier

Absorber

Facing

Used to line the inside of cabinets, compartments and panels where the existing skin light gauge and not capable of providing enough transmission loss.  To get the full benefit from these decoupled absorber/barrier composites, the percentage of open area in the cabinet or panel should be 10% or less of the total surface area.

Adhesive

Damping

Used to line inside or outside surfaces of thin metal or other rigid surfaces to reduce noise generated by structural resonance.  This product group can be applied in sheets or using a liquid damping compound.
