●Shell Roof Boltless Type Ⅲ Shell Roof Boltless Type Ⅲ

K=0.7W/㎡・K（K=0.6kcal/㎡・h・℃）

●Shell Roof Boltless Type Ⅱ Shell Roof Boltless Type Ⅱ

K=0.7W/㎡・K（K=0.6kcal/㎡・h・℃）

●Shell Roof Ｆ-２００ Type Ⅱ Shell Roof Boltless Type Ⅱ

K=0.7W/㎡・K（K=0.6kcal/㎡・h・℃）

●F-170 Shell Roof Boltless Type Ⅲ

K=0.7W/㎡・K（K=0.6kcal/㎡・h・℃）

●Shell Roof Boltless Type Ⅰ　Shell Roof Boltless Type Ⅰ

K=0.8W/㎡・K（K=0.7kcal/㎡・h・℃）

※The value for the overall heat transmission coefficient K is based on a thermal conductivity of 0.045 for glass wool [W/m・k].
