hello,
my vaulted ceiling has no insulation, and it gets cold in that area of the house during winter.
it is an upstairs hallway vaulted ceiling.
a 1920s plaster and lathe ceiling with about 2inch (5cm) gap above, after which is positioned the slanted roof [a 1970s grey membrane/plastic is under the tiles].
to reduce the cold in the hallway,
i plan to put Kingspan Insulation Thermapitch TP10 2400mm x 1200mm x 25mm boards onto hallway side of the ceiling:
1. would i need a vapour paper/membrane etc to stop condensation
2. can i just fix it the kingspan onto the rafters thru the plaster ceiling, without using battens?
thanks
jon
