Can my ceiling be made out of cork?
The painter told me that the ceiling in the living room of my terraced house is made of cork, is it good or bad, what are the drawbacks?
Does it have to be removed or can it be covered with another material on top?
In the old days, cork tiles were used in some ceilings to improve insulation. So if it's in good condition, I'd keep it. No inconvenience, although they are probably 1 cm thick, all helps save energy.
Of course, it's not cork, if it's white, it's porespan vaults.
They are usually used to lighten the stamping load, especially in reforms and new housing, because it's so much cheaper.
I can't find any other advantages other than transportation and installation, but for roof or floor repairs in older homes where the lowest possible weight is required, they are effective.
As an insulator, they are not very insulating, as the beams continue to act as a thermal bridge, and I can assure you that this is noticeable, especially in the summer if it is on the roof.
As acoustical, they are useless, for the same reason, the beams transmit vibration.
To hang light fixtures is a disaster, you either have to find a beam or there won't be one, and with soffits you have to remove the curb and put gypsum board or gypsum wool between the beams.
Quite another thing – to lay porespan panels without partitions and joints beams, then they really insulate, both from the cold and heat, and from noise, not much, but noticeably.
