Teroform® plastic heavy layer/PUR foam for soundproofing mats
Teroform® plastic heavy layer/PUR foam for soundproofing pipes and ducts
Silphon®Yellowfoam-FR for sound insulation of pipes, cables and ducts

Teroform® combination noise control mats for sound insulation in pipes and ducts in building construction.

Glued pipes and ducts. In pipe insulation, 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.

Frequently asked questions (FAQ)

The fire behaviour of building materials is assessed according to their fire and smoke behaviour and classified with a BKZ (fire code number) according to VKF (Association of Cantonal Fire Insurance Companies). These are determined by standardised tests. The fire index is made up of the degree of flammability ( 1-6 ) and the smoke level (.1-.3). Highly flammable and rapidly burning materials (flammability grades 1-2 ) are not permitted as building materials in fire protection. Fire classification numbers 3 highly flammable 4 medium combustible 5 hardly inflammable 5 ( 200? ) hardly inflammable at 200?C 6 not flammable Smoke level .1 strong smoke formation .2 moderate smoke generation .3 low smoke generation Example: Fire code number 5.2 = hardly combustible, medium smoke formation
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
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).
Tedrodem? Kobination sound insulation mat has the BKZ 5.2 (hardly combustible with medium smoke formation)
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.
