Fresh air inlet ALD
This system helps to reduce noise filtering into your home from outside. This is done by changing the current open vents, to hollow acoustic foam that dampens the noise. This system also prevents sudden blasts of wind from entering your home with the aid of a shutter valve and aerodynamic covers located on the front and back of the vent.
