Full Mortised Automatic Door Sweep for Door Bottom Sealing

A door bottom seal is installed at the bottom of the door.
When the door is closed, the seal automatically extends downward to press against the floor, sealing the gap between the door and the floor.
 When the door is opened, the seal retracts automatically, avoiding any impact on the door’s operation and preventing damage to the floor.
The concealed design of the door bottom seal does not affect the appearance of the door.
Once installed, it effectively prevents external dust, odors, insects temperature fluctuations, noise, and light from entering through the door gap, protecting the indoor environment.
 It is the preferred choice for hotels, guesthouses, high-end renovations  clean rooms, and industrial doors.

Automatic Door Sweep FAQs

An Automatic Door Sweep is a mechanical device attached to the bottom of a door that automatically  lowers a seal to auto block gaps when the door is closed, helping to prevent drafts, noise, and pests from entering a space.

When the door is closed, the sweep automatically lowers a sealing strip (usually made of rubber or brush) against the floor or threshold. When the door opens, the sweep retracts, allowing the door to move freely.

No, they operate mechanically. The movement of the door itself activates the sweep, so no external power or batteries are required.

A threshold plate is a good idea, for several reasons:

  • It will help to ensure a good seal is maintained at the threshold, by giving a firm surface for the automatic door sweep to rest against.
  • It can help to prevent weather ingress when used as part of a storm-guard system
  • If you are sealing dissimilar surfaces (eg, carpet and vinyl), the threshold plate can cover the join to prevent both wear and tripping hazards. Our threshold ramps can also easily accommodate differences in floor heights, to make access easier for all.
  • If your floor surface is particularly liable to wear and tear in places below the door (eg, a high level of traffic, or over a carpet that may become compressed over time), then a threshold plate will help to prevent these uneven areas affecting the threshold sealing.
  • Please refer to our threshold plates and ramps for further details.

Yes, many models offer adjustable height settings to accommodate different gap sizes and ensure a proper seal.

We’d recommend you consider using a silicone rubber seal overal type automatic door sweep seals. There are perimeter and threshold sealing products included, and both the carriers and gaskets are impervious to most strong cleaning chemicals, making them ideal for hospitals.

Please note that while these seals will provide a comprehensive smoke sealing solution, if you have a fire rated door then an appropriate fire seal should be fitted in addition.
