bottom door seals

Seals designed to fill the gap between the bottom of a door & the floor underneath are referred to as bottom door seals. Automatic bottom door seals are mechanically spring loaded to lift clear of the floor as the door opens and seal tight as the door closes. They come in different types to be face mounted, semi concealed or fully concealed. They operate over uneven floor surfaces (though care needs to be taken in product selection) & threshold plates can be used where required.

Note bottom door seals are complicated on pivoting doors so please seek additional advice.

The seals shown hear are the most commonly used to address acoustic issues, we have a very extensive range of seals for different special applications - please contact us for more information.
