Combi soundproofing mats, heavy foil/foam | Silphon®Yellowfoam-FR for sound insulation of pipes, cables and ducts

Combi sound insulation mat (spring-mass system) consisting of a yellow, flame-retardant PUR absorption foam (fire index 5.2), laminated with a flame-retardant heavy plastic layer (fire index 5.3) on one side. The combi sound insulation mat can be ordered with a self-adhesive coating on the foam side, with the adhesive layer covered with a removable PE film. The foam side is glued onto the metallic or plastic channels or pipes to be insulated. In pipe insulations, the resulting longitudinal joints should be overlapped or glued together with heavy foil tape (e.g., plastostrip). The main application field is the containment of disturbing flow and impact noise in pipelines and canals caused by the flow of contaminated air, liquid, or bulk materials. Examples include ventilation and exhaust channels, supply lines for wooden pellets or woodchip heaters, plastic water disposal channels, or the like. The combi noise control mats are available in standard sheets or custom-made on request, with or without a self-adhesive foam side.
