1- Per BSAF, 1#/cu.ft. eps has an r value of 3.85 AT 75 degrees F. Important for people living in the north, such as Minnesota, is that the r value at 0 degrees F is 4.55. The R Value goes up as the temperature drops. 2- The exact opposite is true for polyiso. Also it is much more expensive. o So use 30mm Celotex PIR – R Value = 1.35 (OK as the same) • 50mm Kooltherm – R Value = 2.75 o 50mm Celotex PIR – R Value = 2.25 (Too Low) o So use 70mm Celotex PIR – R Value = 3.15 (Higher so better!) • 75mm Kooltherm – R Value = 4.15 o 75mm Celotex PIR – R Value = 3.40 (Too Low) o So use 100mm Celotex PIR – R Value = 4.50 Celotex Foil faced polyisocyanurate (PIR) Insulation board (L)1.2m (W)0.45m (T)50mm Product rating 4.3 out of 5 stars Product code: 5060153760003 2400 x 1200 x 50mm XtraTherm - Celotex High Perfor . 2400 x 1200 x 50mm xtratherm - celotex high.
