Threshold for Door Bottom Sealing

Installing a threshold after adding an automatic door bottom seal can significantly enhance the sealing, waterproofing, soundproofing, pest prevention, and fire resistance properties. It also protects the seal, extends its lifespan, and improves the overall aesthetics and functionality of the door.

Even without an automatic door bottom seal, a threshold still plays an important role. It prevents rainwater and dust from entering, blocks insects, reduces noise, stops airflow, enhances aesthetics and transitions, and reduces wear on the door bottom. It not only protects the indoor environment and flooring but also improves energy efficiency and overall appearance.

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.
