Merfodamp

Anti-drumming with acoustic foam sound insulation
Merfodamp is a combination sheet with a sound insulation acoustic foam at the front and a self-adhesive anti-drumming backing. It is a composite product consisting of a sound insulation foam, 25 mm thick, equal to Merfocell PU, an acoustic foam with an oil, moisture and dust-proof top layer. The anti-drumming, or sound deadening, backing is a sheet of Vibraflex, self-adhesive, that isolates resonances and vibrations in sheet metal.

Merfodamp is used to insulate, for example, steel or aluminium casings and machine enclosures where the temperature does not exceed 70 degrees. The anti-drumming layer functions best when the mass of the surface is doubled, or close to that. Merfodamp anti-drumming with sound absorber can also be applied in combination with a heavier version of anti-drumming material such as Vibraflex for even more insulation. This product is not suitable for soundproofing buildings or houses.
