Polystyrene Ceiling Tiles Redux

[Tracey Suntan-King]

Any fool knows that polystyrene tiles are a big no no in old houses. They burn like mad and drop balls of molten lava onto your head as you try to escape the fire.

However, there seems to be something of a revival being attempted at the moment.

We're renovating a house and I've been looking at the new type (we have a shitty ceiling to conceal) and in a small area, think they'd look good.

They claim to be fire resistant.

Anyone here used them? Any good?

What could possibly go wrong?

Have you considered buying just one tile and attacking it with a blow torch?
You'll know for sure then if they are fire resistant

Depends what market, and to what specs the flame resistance is measured.

The big EU are all for single standards for the single market. Nah. There's French standards AND German standards AND a singular EU standard. Try and tell the French/Germans that it meets the EU, they aren't interested until it meets their own.

If it's been tested and certified (legitimately, not china china china stds) within the last 8 years or so I'd be confident they do not form flaming drops. Any drops instantly drop a grading from M1 to M2 and B1 to B2, French and German respectively, IME.

I would expect the tile to either: behave in way so as to retreat from the flame, or; be flame resistant to withstand a flame without allowing flame spread over a distance set by the spec.

Thanks for the replies one and all, I got a bit excited thinking it would be a quick and stylish (lol) solution to shitey ceilings.

We stripped the textured paint off one ceiling with heat and a scraper which took ages.

Does anyone know if a plasterer can skim over textured paint or has it all got to either come off first or be boarded over?

Get it skimmed, it'll be like having new walls so the paint will soak in. 60/40 with water or use up old paint.
