polystyrene ceiling tiles

[jenhor]

Does anyone know if it would be alright to plasterboard over emulsion painted ceiling tiles and would it be safe. Thank you

Hi Jenhor,

Yes you can plasterboard over ceiling tiles however the plasterboard will have to be screwed into the joists in the ceiling and not into the tiles.

Yes but they'd be sandwiched between 2 layers of plasterboard - one each side - the original above and the new underneath. This would be perfectly satisfactory fire-wise.
Make sure you use long screws - 50mm (or even 60mm) long. You will have 13+10+13mm of 'sandwich' to get through before the screws hit the wood joists.
