Insulation Options: Heater insulation reduces heat loss to the environment. Some heaters may be available with multiple insulation options.
No Insulation: Heaters do not have insulation. They have a lower profile and are useful in areas where space is at a premium, but are not particularly energy efficient.
Ceramic Insulation: Heaters have ceramic insulation. Ceramics consist of nonmetallic minerals, such as clay, that are permanently hardened by high-temperature firing. Most ceramics resist heat and chemicals.
Magnesium Oxide: Heaters have magnesium oxide insulation.
Mica Insulation: Heaters have mica insulation. Mica consists of colored or transparent mineral silicates that are crystallized in monoclinic forms and readily separated into very thin leaves. Mica is valued for its electrical insulating properties and resistance to heat and acids.
Mineral Insulation: Heaters have mineral insulation.
Teflon Insulation: Heaters have fluropolymer insulation made of materials such as Teflon
Fiber Glass Insulation: Heaters have fiberglass insulation. Fiberglass is strong, durable, and impervious to many caustics and extreme temperatures. Fiberglass fabrics are used widely in industry.
