Intumescent strips on old door.

[Guest mdpeake]

Hi all, when it comes to Intumescent strips on old doors would it be necessary to replace them if they do not have cold seals fitted. Also if the strips were to be painted over would they have to be replaced? Thank-you. Mick.

Depends on the door, some fire doors, generally those not protecting escape routes, don't need cold smoke seals.
