Hi,

I've a similar problem... I tried the multiple drill hole technique and found what I thought was a joist, but it seems to be a really thin strip of metal running the length of the ceiling. Has anyone got any thoughts this as I can't find wood? Only these metal strips...

Cheers

It could be that your ceiling is suspended from "Resilient Bars" for
noise reduction from the room above, e.g. the joists run E-W, then the
bars are run N-S from those, and the plasterboard screwed to the bars
instead of the joists.

Thin strips of metal or thin strips of wood? What is the age of the
property? If 50 +years old it is probably lath and plaster

If lath and plaster the wooden strips (laths) will be nailed at each
joist so the nails can be found with a metal detector.

Although not the cheapest, I recommend a Zircon M40

That Youtube video also includes a demonstration about finding
the nails in lath and plaster

Maybe not terrible helpful, but you can use magnets to find the metal
strips.

And if it's thin strips of metal, there probably are no actual joists
(in a suspended ceiling).

Some of the office to living conversions seem to leave the old office
ceilings with metal strips between rectangular pieces of plasterboard or
similar and simply plaster over them to make it level. I call it a bodge
but there may well be wiring in the suspended part and its probably the
cheapest way, till that is you need to find something really solid to screw
to!

It could be an acoustic lath ceiling ......... I fitted these in my
house, you screw clips on each joist with an acoustic pad between clip &
joist. Then clip in tracks at 90 degrees to the joist - screw fixing
ceiling boards to the tracks.

Makes significant difference to sound transmission between floors.
