Just taken up a chipboard floor to find blu polyboard insualtion underneath. Floor has come up due to a leak. I am trying to find 30mm blue polyboard to go back down but would any insulation do? I have been told foil backed roof insulation would be ok.
My concern was the roof insulation does not seem as stiff as the existing blue polyboard. Any ideas and where could i find 30mm blue board from?
