Aluminum foil for sound insulation. Strong noise is not only a major burden but also a health hazard. This is why in the construction sector and in the industry and many other areas a lot of attention is paid to noise protection. Aluminum foils provide better sound insulation and help to eliminate noise sources. They reliably improve fire and moisture protection at the same time.

Soundproofing most of the times only plays a subordinate role. Especially in noisy and loud areas, it is worthwhile taking into account the acoustic specifics of the insulation materials from the very start. One of the best ways to combine thermal insulation and noise protection is aluminum foil.

Aluminum foil: Thermal insulation and noise protection in one. Aluminum foil not only protects from excessive heat and cold, but also ensures an improved shielding against noise and vibrations. A good thermal insulation with simultaneous sound insulation is best achieved by a combination of an insulation material and aluminum foil (as for example in the case of lamellar mats or alu-sheathed stone wool insulating sheets and mineral wool tube shells.

Aluminium with mineral wool insulates heat and sound. The foils ability to absorb sound allows unwanted noise to be picked up directly at the source and prevent its further propagation. Aluminum foil offers 85% effect as a noise insulator. That means, only 15% of the respective sound passes through it. Companies that process insulation materials also appreciate the low eight and easy handling of aluminum foils. In addition, this material is convincing by its sustainability. Furthermore, its good recycling properties and its freedom from odors and pollutants add the convincingness.

Sound insulation in industry

In the industrial sector too, the use of aluminum foil has advantages for sound insulation, including interception of high frequency noise such as the hissing of steam engines. For example, vibration-damping adhesive tape is used here, which consists of a soft but adhesive polymer material and a thick aluminum foil.

Damping films coated with aluminum foil can reduce sheet vibrations and therefore be used to reduce noise emissions of light steel constructions. Sound-absorbing materials coated with aluminum foil are also used for sound absorption and insulation in machinery and engine rooms, construction machinery, vehicles, shipbuilding and mechanical engineering.

Sound-absorbing moldings based on aluminum foils are also recommended for the thermal and acoustic insulation of hot surfaces with temperatures of up to 500 degree C such as catalytic converters, exhaust systems and exhaust gas turbocharges.
