Drylining upstairs room?

[phester]

I am in the process of drylining an up stairs room walls with Kingspan shelter board. I am also going to put up new plaster board on the cealing.

Should this plaster board be foil backed or unfoil backed. The existing ceeling is just plaster into the attic. and there is fiber glass woll in the attic.

have you a cavity wall??
have you insulation in this cavity, if so what type and thickness??
what are you drylining with?
what thickness of fibre glass is in the roof??

Ok rang Cork Building providers. Their shelterboard is TW52 kingspan also available in Xtherm. But Kingspan is better U value from memory for the same thickness


The ceiling pitches about 2 feet from the walls to allow for the high ceilings. Fiber glass was fitted only a year ago by myself. I don't remember the exact thickness but I raised the rafters with 2x2 as the original beams are only 3inches deep. so i think its 4-5 inch of fiber glass.

The kingspan I have mitred and fitted onto the inside of the (room)ceilings as you can not block the eves of the roof in the attic.

So it is TW52 Kingspan
The houses are solid block on flat circa 1929 built
Fiber glass is as thick as I could fit 4-5 inch.

already only a crawl space in attic however 2 feet boarder around perimiter remains uninsulated due to eves meeting joists.

So im insulating inside room on ceiling on walls and sloped ceiling and plasterboarding remaing flat ceiling.
