Question

what is the property of thermal insulating material
​

Answer 1

Answer:

The main requirement of thermal insulation materials is “low thermal conductivity” since heat is transferred through insulation material by conduction (at 373 K, the thermal conductivity of mineral wool is 0.047 W/m.K, that of glass fiber is 0.038 W/m.K, of calcium silicate is 0.057 W/m.K and of magnesia is 0.062 W/m.K).

Answer 2

Answer:

The best thermal insulators have the lowest thermal conductivity; this is the property of a material that measures how well it can conduct heat through its mass. The lower the conductivity measure, the less well a material is able to conduct heat, thus enabling it to trap heat or protect contents from outside heat.
