People feel warmer in the presence of radiant energy and cooler in its absence. Science refers to this phenomenon as mean radiant temperature. Stand in the shade of a tree on a sunny, but cool day; then step into the sunlight. Your body instantly becomes warmer in the sun, more comfortable.
Stepping back into the shade, you are cool; yet, the change in the actual air temperature between shade and sunny areas is negligible.
The human body feels warmer because radiant energy causes molecular friction within the skin and body. When this friction takes place, it creates heat that makes you warmer. In the absence of friction you are cooler because of the lack of molecular friction.
But only your body is affected, not the air surrounding it. So in winter you may feel as warm in a 65 degree room as you normally would feel in a room with a temperature set at 72 degrees.
The thermostat can be set down 5 to 8 degrees Fahrenheit in winter and up the same amount on the air conditioner in summer and yet the comfort level of the human body can remain the same. Heatshield-R20 ceramic coatings raise the mean radiant temperature in buildings in winter and lower it in summer.
Heatshield-R20™ is formulated to have a very small reaction to radiant and microwave type frequencies.
With very little molecular movement there is very little friction, so very little heat.
HOW IT WORKS
The small micron size hollow glass micro spheres which in part make up HEATSHIELD-R20 coatings are pure sodium borosilicate formulated with hollow ceramic spheres. Each closed cell smaller in diameter than a human hair acts as an efficient insulator. Once applied, water evaporates from the HEATSHIELD-R20 acrylic emulsion topcoat and the hollow ceramic spheres align with each other eventually touching, then fuse into a continues membrane, the seamless HEATSHIELD-R20 topcoat and since the microspheres are over 60% void, the entire coating becomes like a flat thermos bottle.
