Seal Coatings Thermal Solutions manufactures a ceramic-based additive that can be mixed into paints and coatings to provide insulation. The additive is made of hollow ceramic microspheres developed from NASA research, which act as a barrier to heat transfer when applied as a coating. By trapping small pockets of vacuum inside each microsphere, heat reflection is improved. When used in paints and coatings on buildings, the additive helps reduce energy consumption and cooling costs by attenuating the flow of hot or cold air through walls, roofs and other surfaces.
