Answer
	Thermo-Shield® is made of 40% ceramic microspheres dispersed evenly throughout the membrane. These ceramics are extremely good at shedding dirt and self-cleaning with rain or even breeze and wind. You can look at a sample of any of our coatings under a microscope and see that a great deal of the surface is ceramic microspheres. In the United Arab Emirates, there are many Thermo-Shield® flat roofs, and blowing sand and dust are always present in this part of the world. Looking at these roofs after 7 and 8 years, they are very white, almost like new. In fact, some consultants actually believed these roofs were less than one year old. The ceramic bubbles, which one can see embedded throughout the surface (under a microscope) are very good at avoiding dirt buildup.
