10 Design Development Estimates Construction vs. Design Estimates Changed to wood ESTIMATED WOOD COST - $142 / SF Actual Cost is $ / SF Newport Elementary School Roof System Closed cell polyurethane insulation provided R 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 for concealed spaces. NFPA 13, /8 type X gypsum board provides more protection for wood roof construction
