Supply air elements

Outer wall air vents (ALD) are essential components for the controlled supply of fresh air in living rooms and bedrooms. They allow for passive inflow of outside air, thereby ensuring a healthy and comfortable indoor climate. Continuous ventilation is particularly important in modern, well-insulated buildings. Therefore, integrating well-designed sound insulation measures into wall construction, windows, and fresh air supply is essential for high living comfort. Our ALD can achieve up to 75 dB standard sound level difference!
