Definitions

  • the damping arrangement shown in Figure 7 is a layered construction in accordance with the invention, wherein the damping layer 2 is made of layers of standard bitumen damping foil, butyl rubber, butyl rubber foil, bituminous heavy layer, bitumen mastic, sprayable bituminous damper, or a combination of these materials.
  • Figure 9 shows a damping arrangement, wherein the damping layer 2 is perforated in order to allow compression in z-direction (or an expansion of the damping material in x,y-direction) during mounting of a strip of mastic.
