I have no experience with fitting any of it, just aware theres lots of variations available from browsing the hardware suppliers.
If there's space for the brush pile or blade, that could help with draughts and noise. You may need to scrape out the paint from the rebate for the 10mm to fit without bulging outwards and not sticking flat.

intumescent strips.
anyone an expert?
i have an upcoming fire inspection of the front (internal) door to my flat. there is no intumescent strip fitted in the frame but there is a channel cut 9.5x4mm so i guess there was one at some point (flat built in 1986) i think the front door is probably an FD30 the internal doors that i replaced had wired safety glass and small chain closers in the door gap so i guess there were some fire safety measures done.
any pointers? not sure what to buy? heat only? heat and smoke? are they flexible so easier to fit? i’m guessing there is a mm of gloss making the channel a tight fit so something easy to ‘persuade’ into that gap.
