It's made from around 90/95% cellulose, unsure on the other 10/5%
Eh?
It was commonly used in Scotland. Having removed them 100s of times and my dad having fitted them originally I can confirm it is.
Celotex? As in PIR insulation or am I off the mark here? Did Celotex make that sarking?
It was a board made by celotex, it wasn't insulation. Same size as an osb board but they shrink over time and sag badly.
How easy is it to remove these? Might be a daft question but i have recently moved in somewhere that these celotex boards are sagging severely and there is a lot of condensation in the loft space
If the roof is off it comes off no problem. If you just want to patch it to hold it up you can use wood to hold it up, just cut it and secure it in between the trusses.
