  • Application and function, automatic door seals
  • Area of application

    • Reduces light leakage
    • soundproofing
    • smoke control

    Example calculation of energy savings:

    Door width 960 mm,

    pressure difference between indoor and outdoor 10 Pa,

    room temperature 25°C and relative humidity of 90 %,

    outdoor temperature 35°C and relative humidity of 70 %,

    floor gap 7 mm

    Without seal: leakage rate approx. 41 m3/h

    With seal: leakage rate under 2 m3/h

    The area of application in which the door is used is mainly governed by the sealing profile material (PVC or silicone). High quality, self-extinguishing silicone seals are used for fire resistant and smoke control doors.


    Retractable door seals are available with single-side or double-side release mechanism. Seals with single-side release (with double doors) are released on the hinge side or on the lock side, depending on the model. Double-side release always means release at the hinge side and at the lock end. With double-side release seals, the sealing profile is raised and lowered faster, which prolongs its life time considerably.


    The sealing profile is pressed automatically against the floor or engages with a threshold as the door is closed.

    Automatic door seals can be distinguished between retractable door seals and sill seals.

    Sill seals are always used in combination with a threshold, it is, however, recommended to use retractable door seals also in combination with a threshold in case of carpet fitted floors or butt joints with different floor coverings.
