What is Reflective Insulation Material?
Reflective insulation, also known as thermal insulation, curtails heat transfer between the insulated surface and surroundings. It helps reduce energy appliances and fulfill energy requirements. It is one of the best materials to minimize the side effects of radiant heat transfer with low utility costs.
The “E” value of reflective insulation material is around 0.03. It implies that reflective insulation is very effective against radiant heat transfer. Other traditional insulating materials like fiberglass and foam have “E” values of more than 0.70. Reflective insulation is different from other methods of curtailing heat transfer. It restricts the movement of heat between the insulating surface and the surroundings, whereas old methods curtail conducive heat for providing insulation. It is highly recommendable for areas with extreme temperatures.
Materials with high reflective properties, like aluminum or other metals, are used to manufacture reflective insulation. Substrate materials like polyethylene bubble wrap, foam, or other low-conductivity materials are placed between the layers of metallic foil. The substrate material is bonded with the foil using an adhesive or lamination technique. This whole setup, when prepared, acts as a barrier against heat transfer between the two surfaces.
Benefits of Reflective Insulation Material
Benefits of using reflective insulation material are:
- Reflective insulation is one of the best materials for improving the overall energy efficiency of an establishment. It barricades the heat movement between the insulating object and surroundings, which results in less use of energy appliances for maintaining interior temperature.
- Reflective insulation materials are lightweight and easy to install. When compared with other insulating materials, it is easy to handle and its installation does not require any expertise. Whether it is an industrial, commercial, or residential building, it is easy to install reflective insulation.

How Does Reflective Insulation Work?
Reflective insulation curtails the transfer of the radiant heat between the insulated surface and surroundings radiated in the form of electromagnetic waves.
Reflective insulation works in the following way:
It diminishes the transfer of heat between an object and its surroundings taking place through:
Conduction:
When air gets heated up it starts moving from a hot object to its surroundings through physical contact, this movement is known as conduction. Thermal energy requires a medium (solid or fluid) to flow from a hot region to cool. For example: when transfer of heat takes place between the hot exterior walls of a house to the interiors.
Convention:
The movement of air from a high-density area to a low-density density, the process of convection takes place. The main cause of the transfer of heat under this method is due to physical air movement. Every time when hot air rises up and leaves its place, cool air rushes to cover up the gap created. Example: the air that comes out from the chimneys of industrial plants and homes.

Radiation:
When the transfer of heat requires no medium it is known as radiation. It takes place through space and a vacuum. The movement of infrared rays from one medium to another without any external help is radiation. Example: When the earth’s surface absorbs the sun’s radiant energy when it reaches the earth.
Reflective insulation that is also known as radiant barrier insulation primarily reflects away the heat that falls on its surface. It creates a barricading against it and prevents it from penetrating through its surface to the surface of the insulated material. Materials like aluminum foil are used that contain a layer of air sandwiched between its surfaces. This mechanism hindered the transfer of heat that happened through any of the above methods.
It is necessary to put reflective insulation material at an angle of 90 degrees (perpendicular) to the radiant heat. This angle helps the material to interact with the maximum radiant energy and provides better results. Areas with high temperatures are the most suitable for reflective insulation.
Applications of Reflective Insulation Material
