Thermal Insulation Testing Method

The thermal conductivity of materials governs the rate of heat transmission through them which thereby gives a measure of their insulating properties.

Though the performance of insulating materials is greatly influenced by their thermal conductivity, many other characteristics, including density, thickness, specific heat capacity, and thermal bridging, must also be taken into account. To effectively offer thermal insulation, materials with high thermal resistance values are utilized in the densest and thickest shapes. In order to wrap thermal insulation over intricate systems or fill small gaps, flexible shapes are preferred. Asbestos, which was once widely used, has a remarkable resistance value, but its carcinogenic effects are well-known and are linked to a wide range of serious, chronic health issues.

In a nutshell, thermal resistance is a unit used to measure or grade an insulating material’s resistance to conductive heat movement. The insulating efficiency increases with this number.

The benchmarks utilized to evaluate thermal insulation comprise, but are not restricted to, ASTM E285, ASTM C549, ASTM C553, and ASTM C739.
