DOOR BOTTOM SEALS - TS8Si

DOOR BOTTOM SEALS - TS8SI

Seals that are designed to fill the gap between the bottom of a door and the floor or sill are called Door Bottom Seals. There are two common versions of these seals; the mechanically lifting automatic seal and the sweep seal. The operation of both of these seals is enhanced when they      are used in conjunction with a low profile threshold plate which has been fixed to the sill immediately under the door.The automatic door bottom   seal lifts automatically as the door is opened and conversely lowers to seal as the door is closed. This ensures that the seal does not impede the normal function of the door, allowing the seal to lift clear of carpets and other obstacles. They look neat if face mounted to the door and some versions can even be fully morticed into the door, out of sight. The sweep seal operates by bringing a flexible seal, mounted on the door, into   contact with a low profile threshold plate. These seals are often made of a strip of flexible PVC (rubber or brush) mountednto an aluminium holder.


A concealed, acoustic automatic door bottom silicon seal for medium temperature  smoke and fire door applications.

TS8Si is spring loaded to lift clear off the floor as soon as the door leaf is opened by a few millimetres. Mounted into a 15mm x 34mm groove that has been morticed into the bottom edge of the door, it is operated automatically by pressure against the door jamb on its adjustable strike block. TS8 Si can also be fitted into the bottom hollow rail of an aluminium door by the fabricator.
