Cardatec Door drop-down seal D5 17x20 mm

The D5 door drop seal from Cardatec is an innovative solution for improving room acoustics and air circulation. This seal is specifically designed for use on doors and provides effective sound insulation of up to 52 dB. It features a damping cylinder that extends the closing time of the seal to about 6 to 8 seconds, allowing for a smooth and controlled closing motion. When the door is opened, the seal quickly retracts, ensuring easy handling. This seal is particularly advantageous in rooms with inadequate continuous ventilation, as it helps minimize the negative pressure when the door is closed. It is suitable for various door materials, including wood, metal, and plastic, and can be used with floor air gaps of up to 16 mm.
