JFE Galvanizing & Coating developed dry heat-insulating-roofing
system, “Resino Family Roof.” It consists of a steel deck-plate, “Hi-Deck R100,”
for concrete slab moulding as the backing and a heat insulating and a water-proof
sheet. Steel deck plate of the backing is good at the design and is authorized
for the fire-resistance of roof-30 minutes with the span of 4m. The unique form
of Hi-Deck R100 improves adiabatic performance by about 10%. When rock wool is
filled inside of the deck plate, power sound level of rainy noise is decreased
by maximum about 9 dB.
