Thermal Insulation Products
The word Thermal insulation refers to insulating something from heat transmission. Most often, however, the discussion of thermal insulation is about construction and structure insulation. The building industry uses thermal insulation to reduce the heat loss or heat gain through the house/factory/shed envelope (external walls, windows, roofs, foundations, and more).
Because a thermal insulator is not a good heat conductor and has low thermal conductivity, thermal insulation is used in buildings and manufacturing processes to prevent heat flow: both heat loss from low temperatures and heat gain from high temperatures.
