Polyurethane foam boards are used in construction for insulation. Wetsuits provide both thermal insulation and flotation. They aid in flight, thermal insulation, and waterproofing. This is lightweight and has better thermal insulation. Pool noodles are similar to some types of industrial and residential foam insulation for pipes. Some of the thermal insulation tore loose, raising the cabin temperature to . Uncoated fabrics provide the next level of heat insulation and light absorption. ACPs are frequently used for external cladding or facades of buildings, insulation, and signage. Corona causes degradation of electrical insulation and emission of ozone and nitrogen oxide. The silk is used in thermal insulation, acoustic insulation, and oil absorbents. Manufacturers of glass-fiber insulation can use recycled glass. A consequence of moulting is the loss of thermal insulation. Fleeces are used as material in making alternative products such as wool insulation. By means of a thermographic camera thermal bridges and inhomogeneous insulation parts can be identified. This equalizes electrical stress on the cable insulation.
