[QUOTE 4249487, member: 9609"]it is the top floor flat with a flat roof above, and there is an area in the flat where the ceiling is about a foot lower than the ceilings in the other rooms, I was curious what was above there as I am in the process of planning what to do with the property. With the age of the construction asbestos has to be a big concern, they seemed obsessed with it in the 50s and 60s
Anyhows, I bored a few 4" holes through it yesterday. I was quite inventive, I taped a large clear plastic bag to the ceiling with the drill inside, then wearing my mask just in case, I formed the holes creating zero dust outwith the bag.
Thankfully it is just plasterboard, a very thin board 8.5mm thick + 1.5 skim. but it is certainly paperbacked gypsum. in fact some of my photos show the word "gypsum" on the back of the board.
There is zero insulation between the ceiling and the roof. and sadly with wooden joists I have no idea how it can be insulated without re-roofing
The only thingI have found in the flat that almost certainly contains asbestos are the old night store heaters, they are too big and heavy to move as one, I will leave them until the property is gutted, presumably the contractors will know what to do with them.[/QUOTE]
Good to hear nothing was found.
As for insulating the ceiling, just put some brackets spanning the joists and cut in some kingspan.
