“Shadan roof 20” uses heat shielding steel sheets as its standard material to control increases in temperature. It also has air-circulating heat-retentive material to limit increases in temperature in the summer and helps dry the foundation making the whole roof breathe.

Natural Ventilation
Air brought in through the intake of the roof-edge parts (aluminum extruding mold material) ventilates more natural air through the grooves in the heat-insulating material that serves as a support for the roof. This helps the roof foundation stay dry as well as preventing heat rises by constantly circulating hot air in the roof.
The standard material is heat shielding galvalume steel
We use heat-shielding galvalume steel as our standard material with its heat-reflective paint, effectively reflect near infra-red and keeping the roof temperature low. (Standard colors black, brown, silver-black and moss green)
100% recyclable
This doesn’t have heat-insulating material on the main roof so all unused materials and materials not needed due to future renovations can be recycled on future renovations. This roof material doesn’t produce industrial waste.
Fireproof for 30 minutes
This has 30 minute fireproof capabilities found in steel construction (using wood strips and cement sheets over 18mm as the roof foundation).
