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.
Beside this, can aluminum foil be used as a radiant barrier?
Aluminum foil has the radiant barrier properties of high reflectivity and low emissivity. That means the foil reflects much of the roof’s heat back upward. The low emissivity property of the foil reduces the amount of heat that the foil radiates on through to the attic insulation below.

Use of a Viscoelastic Damping Compound or MLV converts sound waves into heat, weakening the waves before reaching the next layer of mass.
