Frequently asked questions (FAQ)

The basic rule when using bituminous or plastic heavy foils as anti-drumming when bonding sheeting is: The sheet thickness x 2 gives the thickness of the anti-drumming foil, 2/3 of which is applied to the surface.
Through the principle of mass increase (weighting), heavy foils for sound insulation bring about a decisive improvement in the (airborne) sound insulation properties of lightweight construction elements made of wood, wood-based materials, plasterboard or thin sheets of steel, aluminium or plastic. Weighting means full-surface connection (gluing) with the light elements. This increases their weight. Thickness and bending stiffness, however, are only minimally increased. Thereby high sound insulation values can be achieved with slim constructions. In addition, due to their high internal damping capacity, heavy foils have an excellent effect as anti-drumming material, e.g. for thin-walled sheet metal constructions (anti-drumming effect).
Heavy foils are heavy, viscoelastic foils based on plastic or bitumen, which are mainly used to improve the airborne sound insulation (anti-drumming) of thin-walled sheet metal constructions or lightweight construction walls as well as for structure-borne sound insulation (absorption). The heavy foils from the Vibraplast range have various fire protection certificates such as the fire classification number (BKZ) 5.2 or 5.3 according to VKF / UL 94 / EN 45525 / DIN 4102-1 B2
For vertical (wall) and overhead (ceiling) applications of heavy foils, which place very high demands on the tensile or shear strength of the bond, we generally recommend increasing the strength of the bond by applying an adhesive film to the surface of the construction material to be weighted down (contact adhesive, adhesive spray). Mechanical safety fastenings (metal strips, wooden slats, wide-head nails) can also be provided for this purpose.
