Drop down door seals work as the name suggests – they drop down automatically when a door closes, to form a secure seal.
If a fire door has a gap of more than 10mm along the bottom, its integrity is compromised and it allows fire and smoke to pass through and spread. In this case, the door requires a threshold seal to ensure it can withstand and protect against smoke and flames in the event of a fire.
We stock drop down door seals from a variety of different manufacturers, including Applique 37, Lorient, Exitex, and Norseal.
