Pocster Posted February 10, 2022 Share Posted February 10, 2022 I've got to start thinking about my suspended ceiling on the underground mega dungeon. Current 'ceiling' is beam and block or just concrete. I can't seem to find any details about the minimum distance the suspended has to be from the existing. I *recall* from somewhere 100mm. That correct? We are planning recessed lighting. But again as modern recessed lights tend to generate very little heat and are slimmer ( plus also zero timber i.e flammable above ) then perhaps I need not worry?

Dudda Posted February 10, 2022 Share Posted February 10, 2022 No regulation on what a suspended ceiling void needs to be. You can have it 20mm if you want. It's about what size do you need to hide the services. If you've 100mm waste pipe then it's probably going to be 130mm or so to allow for the pipe and fall. 1 Link to comment Share on other sites More sharing options...

Do it in metal frame, then plasterboard as normal. Just like a timber joisted ceiling but with fewer cracks. Link to comment Share on other sites More sharing options...

HMMMM! 92m2 But that's allowing for finished wall to finished wall. Bet @Thorfun is cheating and using just floor area. I also have my dungeon courtyard - I should add that in really; which is 24m2 So total is 116m2 - funny how I win by 1m2 - my measuring though is rather "subjective" - anyway ... I WIN!

Temp Posted February 10, 2022 Share Posted February 10, 2022 (edited) Our first floor is beam and block. The beam supplier provided some metal clips to hold battens to the underside of the beams. I think they were 22mm ish deep. So the void under beams was just the batten depth 22mm. Under the blocks the depth available for downlights was 50+22+12= 84 or 85mm ish. Back then that was marginal for fire and sound rated GU10 style downlight housings but shouldn't be an issue for LED these days.

No , no , no . If you could see what I can see you’d understand. I could put an access panel every 1m I suppose . Link to comment Share on other sites More sharing options...
