Xtratherm or Kingspan

Cork Building providers call xtratherm product shelter board but the only refference to it that I can find online is called thermal liner board.

from the NSAI website it says that XTB mechanically fixed has a conductive value of 0.023 W/mK where as TW52 has a value of 0.027W/mK

So if I use 50mm of insulation from
Kingpsan is 1.852 m2K/W
Xtratherm is 2.17 m2K/W

So xtratherm appears to be 15% better and at last check was cheaper than kingspan

Am I correct in my figures and assumptions made above

Thanks
Alan
