[QUOTE="perfectionist, post: 254653, member: 1603"] Energylite is the equivalent of Owen Corning in America. Owen Corning used to be in SA but a European company bought them out hence the name change. The products are exactly the same except one follows European standards and the other American. Energy-lite is better than "U" Therm by a slight amount in the lower frequencies but it does cost more. Owen's Corning 701 is the same as Energy-lite 47.5 Owen's Corning 703 is the same as Energy-lite 80 What you want is Energy-lite 80. I used to have the NRC values for Energy-lite 80 but I can't find them now. If you look in the graphs though you can see the NRC value for the 47.5 and the transmission loss in dB to frequency. 80 will obviously be much higher.
