Automatic Door Bottom FAQs

What is an Automatic Door Bottom?

An Automatic Door Bottom 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.

How does an Automatic Door Bottom Work for Door Bottom Sealing?

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

Do Automatic Door Bottoms Require Power or Batteries to Operate?

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

If I Fit an automatic door Bottom, do I Need to Fit a Threshold Plate Too?

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 Bottom 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.

Can Automatic Door Bottom for Different Gap Sizes for Different Door Bottom Sealing?

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

I'm Working on a Hospital Project that Needs a Sealing System that will Stand up to Rigorous Cleaning. What do you Recommend?

We’d recommend you consider using a silicone rubber seal overal type automatic door Bottom 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.
