Is Celotex better than rockwool?
90mm Celotex or equivalent will give the best insulation, it’s insulation factor is about twice that of Rockwool. But it needs cutting which takes time and is messy. Rockwool might be easier to install, although you have to keep it in place somehow and if installed vertically ain’t so simple. Its also cheaper.
What U-value does 100mm Celotex give?
0.2 W/m2k
Using Celotex to fill the cavities is more expensive, but you will only need to use 100mm celotex to achieve a U-value of 0.2 W/m2k . The only thing to bear in mind here is that you still need to keep a residual cavity on the outside – but this means the cavity can be marginally thinner.
