•Un aislante térmico es un material usado en la construcción y la industria y caracterizado por su alta resistencia térmica. Establece una barrera al paso del calor entre dos medios que naturalmente tenderían a igualarse en temperatura, impidiendo que entre o salga calor del sistema que nos interesa (como una vivienda o una nevera).
•Uno de los mejores aislantes térmicos es el vacío, en el que el calor sólo se trasmite por radiación, pero debido a la gran dificultad para obtener y mantener condiciones de vacío se emplea en muy pocas ocasiones. En la práctica se utiliza mayoritariamente aire con baja humedad, que impide el paso del calor por conducción, gracias a su baja conductividad térmica, y por radiación, gracias a un bajo coeficiente de absorción.
A thermal insulator is a material used in construction and industry and characterized by its high heat resistance. Establishes a barrier to the passage of heat between two media that naturally tend to equalize in temperature, preventing heat from entering or leaving the system of interest (such as a home or a refrigerator).
• One of the best thermal insulation is a vacuum in which heat is transmitted only by radiation, but due to the great difficulty in obtaining and maintaining vacuum conditions are used rarely. In practice is mostly used with low humidity air, which prevents the passage of heat by conduction, thanks to its low thermal conductivity and radiation, through a low absorption coefficient.
