Raven RP114 Intumescent Door Bottom Upgrade Seal

RP114 is a door bottom intumescent fire and hot smoke seal that is designed to salvage non compliant fire doors where clearances exceed 10mm under fire doors as per AS/NZS 1905.1.

The simple retro-fit design avoids costly door replacement and the need to remove the door during installation.RP114 is approved for use on leading proprietary fire doors.


RP114 should just clear the floor during door opening and closing.
To avoid the seal fouling on uneven or sloping surfaces, the finned gasket should engage an approved Raven threshold plate.
This will enhance the other icon sealing functions.

Door Bottom Seals

Seals that are designed to fill the gap between the bottom of a door and the floor 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. The seals are often made of a strip of flexible PVC (rubber or brush) mounted into an aluminium holder.

Note: Ensure that the floor surface is lower than the sealing surface of the threshold plate to avoid sweep seal from fouling.
