Steel door set cold smoke seals

[Prometheus]

Currently inspecting a building and now at a section that is 100% steel doors, all specified FD60S on the fire strategy but none have smoke seals of any kind.

Is it necessary to add smoke seals? and if so what would be a suitable product? stick-on ones don't sound very good to me, it's an environment prone to temperature changes, high  humidity and damp (yes many of the doors are rusty and will be replaced)

Thanks

Are smoke seals necessary given the use of the building and the location of the doors?

Did any of the doors ever have smoke seals fitted? 

If you can identify the manufacturer of the doors to confirm their fire rating they may be able to recommend a suitable seal, otherwise you could contact a door seals specialist for advice.

If smoke seals are necessary then, in my experience bat-wing seals fitted into the corner of the door frame rebate and at the corner of the astragal for double leaf doors are the most suitable, provided that there's room in the rebate to accommodate the thickness of the seal.  As they are self adhesive, the surface will need to be very clean for them to adhere.

The fire strategy specifies them as FD60S so yes.

No, none of the doors have had smoke seals fitted.

They are indeed 60 minutes as the original manufacturer label is still one soem of them.

I guess batwing seals are the way to go.
