I'm doing some research on cavity wall insulation for my extension.
I note that there is a full fill 97mm PIR from Celotex (CF5000), which is better performing than the Isover CWS 32 100mm.
Is there a reason why I would not go with the Celotex over the Isover? I have been reading lots of conflicting information and would like to know what people's opinions/experiences are.
Thanks.
