Bitumen and filler-based sound deadening sheeets (used to be called lead bitumen). Vibraflex is a self-adhesive mass / sound deadening sheet that insulates resonances in plate material, such as aluminum, plastic or steel.
Vibraflex is used for the insulation of vehicles, in yacht- and shipbuilding, for deadening sounds of facade claddings, casings, steel stairs, and in case of water hammering. Anti-drumming works best when the mass of the surface is doubled (or something coming close to that).
Two variants are available, Vibraflex UF, sheets of 1 x 1 metre, and a variant packed in practicle boxes. Read more about anti-drumming on our tips page “What is Anti-drumming”.
