Supply air elements

The outer wall air vents serve as passive air supply for living rooms and bedrooms. For a high level of living comfort, it is essential to integrate well thought-out sound insulation measures in wall construction, windows and fresh air supply.

Our ALD can achieve up to 75 dB standard sound level difference!
