Fire door upgrading.
It is common to have non rated doors in buildings that need to be converted to fire rated doors. This could be because of renovations, change of regulations or simply human error.
Most times, existing frames do not need to be removed, but modified so fire doors can be fitted.
With single doors, requiring a 2hour FRL, the door stop is built up to 25mm by fitting a metal capping
Another option is the use of Kilargo KG5102 intumescent seals, placed in the corner of the frame rebate. This method is also approved for a 2hour FRL, depending on the wall construction.
