Product details

The Cardatec D5 door drop seal is an innovative solution for improving room acoustics and air circulation. This seal is specifically designed for use on doors and features a one-sided, time-delayed release that allows for a closing time of approximately 6 to 8 seconds. A damping cylinder ensures that the seal gently and controlled descends when the door closes and quickly rises again when the door opens. This is particularly advantageous in rooms with insufficient continuous ventilation, as it minimizes the negative pressure when closing the door. The seal also provides sound insulation of up to 52 dB and is suitable for floor air gaps of up to 16 mm. It is compatible with various door materials such as wood, metal, and plastic, ensuring effective sealing.

  • One-sided, time-delayed release for controlled closing
  • Damping cylinder extends closing time to 6 to 8 seconds
  • Quick rising of the seal when opening the door
  • Sound insulation up to 52 dB for improved acoustics
  • Suitable for wood, metal, and plastic doors.
