Closed cell polyurethane insulation provided R-21 R 21.4 4 ASHRAE, energy code, section 8 allowed reduction in R-value because of reduced air infiltration provided by closed cell insulation If exposed closed polyurethane requires intumescent coating, 5/8” type X gypsum board is used to protect insulation Volume between “I” joists less than 160 cubic feet; no sprinkler system required i d ffor concealed l d spaces. NFPA 13, 8.15 5/8” type X gypsum board provides more protection for wood roof construction

Ume Ryokuho Junior HS in Ume‐machi, Oita
People are attracted to wood because of its: • Biophilia = “love of living systems” • Visual variety, variety natural irregularity and expressiveness • Warmth, softness and a calming effect Principles of “Evidence-based Design” show that occupants respond positively to wood • Schools in Japan are built with wood because students respond positively • Healthcare facilities in Canada have experienced positive p p patient response p due the humanism incorporated in the architecture of the facilities
