All,
I have been given a quote for 60mm Internal Wall insulation boards. The suppliers says the following.
hi the insulation board will be either ecotherm or recticel, the board does not carry a 'u' value as that is something that is calculated over the entire construction , it would have an r value of 2.73m2k/w comparative to say that of celotex or kingspan.
Is this true? As looking at Kingspan website 60mm is 0.020 W/m.K (= 45 mm)
HELP
Cheers
