Is that those tiles ?

I did up a commercial bar 15 years ago that had them , with all the little holes and things . On a budget of next to nothing , I cut plywood to size and varnished it , and replaced every 5th or 6th tile with these . Still pretty boring , and we had the luxury of height , but I then did more plywood pieces , 200mm wider and longer . Half these I did in a mid brown stain , the other half in a reddish cedar stain , added 4 downlights per panel , in holes drilled into these panels , and suspended these mostly 100-150mm lower , with polished stainless steel threaded rod .

Definitely no asbestos

How do you know there is no asbestos? Have you had the ceiling tested by professionals?

I’ve been assured in writing & confirmation with the body corporate that there is no asbestos.
