Simulation for Effectiveness of Heat Shield Paint
The heat shield paint is one of the most effective way to reduce the radiant heat
restraint in the inside of the building.
You can expect to improve the work environment by reducing the temperature inside of the building. We prove theheat shield paint, Adgreencoat, has the own-distinctive functionality, such as high solar reflective and heat exhaust,
which can effectively release the heat from the sun.

Notes

※STEEL PLATE ROOF STRUCTURE （*Proof level by the maker）

1. As the simulation results, it significantly reduces heat load fromthe roof (radiant heat) by the heat shield paint, Adgreencoat. Also
it is to contribute greatly reducing the room temperature.

【Before 56℃】

【After 36℃】

2. In consideration of radiant heat and the humidity, the sense ofsummer heat is greatly reduced. In the state of no air conditioning, I
can expect a reduction of about 4 ℃ indoor temperature.
