‘Our heavy acoustic foil is the perfect product for dampening structure-borne sound and anti-drumming. It has a high surface weight – and an extremely small material thickness. It is popular among our customers above all in chassis and vehicle production, machine construction and for use in air ducts, air-conditioning and lifts. I am happy to recommend the heavy foil to reduce material vibrations and vibrations in garage doors, doors and steel containers.’
