Second layer

Acoustic dampling layer made from PVC which provide optimalinsulation of soundfrom outside.Meanwhile it weakens sound wave and frequency by reducing viberation.

Third layer

Aluminium foil with excellent metallic sound insulation, and free of electromagnetic shielding effect. Moreover, the reflective surface can change the sound wave angle.
