ceiling wallpaper

Hi Normal anaglypta is class Fire rating „C-s2,d0“ according to EN 13501-1 corresponds to „B1“ (fire-retardant) and should be no more dangerous than the contents of a room. It says in the instructions that it's for walls and ceilings. But it must be prepared and well stuck down or adhered to the substrate, any paper partly hanging off would obviously be a hazard. Certainly never consider polystyrene warmaline or polystyrene tiles they would be a fire hazard. You might also want to consider fire retardant paint 'non intumescent' as well if you were worried about using blown vinyl, remind your landlord about smoke alarms as well if they're not fitted, hope this helps.
