A material applied to retard the flow of heat.
Any material high in resistance to heat transmission that, when placed in the walls, ceiling, or floors of a structure, will reduce the rate of heat flow.
insulation designed to resist the transfer of heat; most JM fibre glass insulation provides thermal and sound control.
Material that is used to cover surfaces to reduce heat loss or gain by retarding heat flow through the material. Effectiveness is measured by R-value in units of hr-ft2°F/Btu or, in SI, m2°C/W. The higher the R-value, the more effective the thermal insulation. For roofs, the maximum thermal conductance (C value) is 0.5 Btu per hr-sq-ft°F (2.8 W per m2 per°C).
A material applied to reduce the flow of heat.
A material used to reduce heat flow.
The property of a fabric or garment to prevent heat loss between one surface and the other. Important in outerwear garments.
The term thermal insulation can refer to materials used to reduce the rate of heat transfer, or the methods and processes used to reduce heat transfer. Thermal insulation is the method of preventing heat from escaping a container or from entering the container. In other words, thermal insulation can keep an enclosed area such as a building warm, or it can keep the inside of a container cold.
