It has for quite some time been realized that painting the top of a structure white reflects daylight and lessens its temperature.
In any case, by what amount and are there disadvantages to doing it?
In a new BBC meet, the previous UN Secretary General Ban Ki-moon proposed that this decrease could be just about as much as 30C, with the inward temperature of the structure falling by as much as seven degrees.
So where do these figures come from and does China reflective Membrane manufacturers more extensive exploration back this up?

In 2017, in excess of 3,000 city housetops were painted utilizing both white lime and an exceptional reflective covering.
Referred to just as “cool material”, this cycle is intended to diminish the sun based radiation retained, which thusly implies less warmth is moved inside the structure.
Cool rooftops likewise produce away some warmth ordinarily held by a structure, cooling it further.
