Based on the heat resistant medium and after adding special additives and ceramic microspheres, UNIVOLEN thermal insulation coatings are manufactured for energy saving due to reducing heat losses from ovens, furnaces or refrigerators. These microspheres are used in manufacturing tiles used for exterior cladding of space shuttle. These coatings reduce energy from 10 to 20 percent in practical. The selection of coating is same as heat resistant coating selection. These coatings are named as UNIVOLEN INSULMIX, UNIVOLEN H R T I 200, UNIVOLEN H R T I 400, UNIVOLEN H R T I 600, UNIVOLEN H R T I 1200 and UNIVOLEN H R T I 1800.
