Been trying to work out the comparison u value of using celotex/kingspan or rock wool. Heard that you only need 100 mm celotex compared to 225mm rock wool?? Google can help me or may be I just can't find it.
Anyone know the craic??
Looked at a condensation issue and the roof space has no insulation so it's cold spotting.
It's a f**k on getting above the roof as access is tight so rather than using itchy scratchy insulation was planning to use insulation slabs just divvent naa who much like.
