Vibration damping tapes particularly useful in reducing the noise levels produced by resonant vibrations in light gauge metal panels.

These tapes / sheets are self-adhesive and provide a simple method of achieving dramatic control of panel vibration and its associated noise. They are easy to cut and can be used on virtually any smooth surfaced material. The material is so flexible that it can easily be moulded around awkward surface shapes. Unlike many other damping materials on the market this product is not effected by cold temperatures so does not crack and break.

These sheets are made from a unique, high density, highly visco-elastic synthetic material whose efficiency is derived from the use of a carefully formulated polymer with additives. It is ideal in all situations which require maximum effectiveness for minimum weight and thickness.

As a general rule to maximise efficient vibration damping:-
(1). Damping materials should be applied to the surface section where the vibrational energy causes the most bending or flexing. These are usually the thinnest sections or the central areas of larger sheets.

(2). The stiffness and mass of the damping material should be comparable to that of the vibrating material so generally single layer damping materials need to be 2-3 times the thickness of the vibrating surface to which they are applied. However this material will produce dramatic results when applied to metalwork even up to 5mm thick !

These visco-elastic rolls are also available in larger roll form 6m x 1m.

USES

1. Metallic construction consisting of a KAL-ZIP element with the corresponding fixing, profile and fretwork sheet.

2. Metallic construction + bituminous damping sheet + 60mm thick 40kg/m² mineral wool compressed down to 50mm during assembly.

3. Metallic construction + T50 damping sheet applied to only 50% of the surface of the metallic element compared to test 2 + 60mm thick 40kg/m² mineral wool compressed down to 50mm during assembly.
