Have a couple of fire doors fitted with intumescent strips but have been informed they must also have a smoke strip. It's an old house and the gaps were Ok for intumescent strips but not for smoke brushes. Any ideas?
Have seen these "Surface mounted fire door seal kits - 60 minute- fire & smoke".
Are they any good?

I don't quite follow, instead of a smoke seal you fit a smoke seal and brush.

Yes, we've tried them. As I say it's an old house and there are uneven gaps between the door and frame. That's ok with intumescent strips which will expand to fill the uneven gaps but when we fit a smoke strip you might be tight in one place and a gap in another. These surface mounted strips look like they would solve the problem but was wondering why they are not more widely used.

Can you not re-route the channels to fit the next size up of strip?

Brooks has only one size & Buckleys have various withs but the pile is the same. Have ordered some of those surface mounted strips as they got good reviews.
