If you have the beam exposed it needs to be painted with fireproof paint. Or if you're my local building control you ask that even if it's being covered by fire board anyway

I think they're meant to be employed with a warm roof, which I assume has some sound dampening properties. Obviously that brings in extra building roof height considerations as it's a less efficient use of space. But then it looks nicer.
Cleaning is a bit of a pain. My folks old house had the old fashioned French equivalent. The non-varnished beams were always filthy and impossible to clean. The varnished ones were hooverable. Either way you don't want grain that can snag.

That's a green balaclava?

As someone’s already mentioned, this only works with a warm-roof build-up. Ours has 170mm of PIR insulation on top of acoustic mat, above the birch ply sat on the joists.

Warm roof build up so no compromise on insulation - timber roof structure doesn’t typically need to be fire protected - steels holding up the house need fire protection (boxing in - or paint coating if you are doing the industrial exposed look) . Surface spread of flame may need consideration but there are clear coatings available. Acoustic separation - no issue for back extension / loft situations obvs or in private dwellings (pretty sure) - if it was separating floors for flats - yes.

@Mr_Smyth
With the current zeitgeist for exposed joists are there any issues with fire stopping, sound or insulation?
I get they add a feature but are they one of those things that look great on TMH/Deezen/Moodboard created by millennials wearing orange beanies indoors but the reality of living with them comes with compromises?
