Hi,

A question about the pitched roof insulation. I got a quotation today, on the pitched roof insulation from the hardware shop in my area. I was told, to use kingspan tf70 instead of k7 for that, as it is a.lot cheapper and that is, according to what they say, what most people do. I am wondering and hoping to get an advice on that, as from what I read on the specs sheets for both products, they look nearly the same. There is a 10% difference between the U level (0.02 vs 0.022), but the TF70 is designed for floors, not roof.... So, will it b ok , to use the TF70 ?
Thanks
