Alu Acoustic board - straight element with double torsion ending

Alu Acoustic board is used as a load-bearing element for pipes in dry underfloor heating. Fiber wood’s physical properties ensure optimal thermal insulation and prevent the vibrations’ transmission. The boards are available in various configurations based on the technical conditions of an investment. Alu Acoustic boards are covered with an aluminium foil, which act as a radiator and receives heat from the side of the pipe and distributes it evenly over the board surface. The straight element with double torsion ending is used to run the pipes straight ahead and to meander with them on the walls of the building.
