What Are the Qualities of Good Thermal Insulation Sheets?

Thermal insulation is required in a variety of settings in order to ensure that heat does not transmit from one place to another. Just to give you an example, in the steel and foundry industry, thermal insulation of furnaces is required to ensure the safety of the staff and the safe functioning of the equipment in the factory. 

There are certain requirements for an ideal material for making thermal insulation. For example, mica sheets are used in various industries for thermal insulation. Like that, there are other insulating materials available also. In this post, we will look at the three main qualities of a good thermal insulation sheet.

Thermal resistance

Thermal resistance is the opposite of thermal conductivity. A good thermal insulation sheet comes with high thermal resistance. For example, mica sheets are stable up to the temperature of 1000 degrees Celsius. 

Fiberglass thermal insulation sheets are stable up to 900 degrees Celsius. Ceramic fiber thermal insulation sheets are stable up to 2000 degrees Celsius. All of these materials have high thermal resistance, and they do not allow heat to pass through them.

Moisture resistance

A good thermal insulation sheet should have low moisture permeability. Low moisture absorption ensures condensation and corrosion are minimized. It means it can be used in environments exposed to moisture. 

For example, mica sheets have low moisture permeability. They do not absorb moisture and can be used in environments exposed to moisture. On the other hand, fiberglass insulation is not waterproof. They cannot be used in environments exposed to moisture.

Chemical inertness

Chemical inertness is another important property of a good thermal insulation sheet. A thermal insulation sheet is used in a high-temperature environment. It should not react with other gasses and materials to produce fire or chemical fumes. 

Mica has brilliant fire-resistant characteristics and is chemically inert. It does not react with other elements to produce toxic fumes on burning. Similarly, ceramic fiber is also resistant to almost all chemicals and can be used in applications where other materials fail.

Which thermal insulation sheet should I choose?

The choice of the thermal insulation sheet depends on the application of the sheet. Apart from that, cost also plays a big role in choosing an industrial thermal insulation sheet. Mica thermal insulation sheets are most preferred in the industry due to their affordability, flexibility, and ability to be used in electrical environments.
