Aluminum foil for Bitumen membrane  

For purposes of insulation aluminum foil is characterized by the following properties:

heat resistant

impermeable

non-flammable

light

ageing resistant

UV-stable

Aluminum foil not only protects from excessive heat and cold, but also ensures an improved shielding against noise and vibrations.

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.


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 turbochargers.
