valve insulation coverHeat is a perpetual byproduct of automotive and industrial applications. Without appropriate treatment, unchecked heat can create a dangerous work environment for personnel and nearby equipment. Heat shields are specially engineered to reduce the effect of high temperatures in areas surrounding heat-generating equipment. Firwin’s heat shielding products are specifically designed to protect equipment and workers from high levels of heat in a variety of applications.

What Is a Heat Shield?

A heat shield is any material that serves as an obstacle to prevent heat from entering the surrounding area. It can be a removable insulation blanket or shield that is composed of heat-resistant material, or a permanent  hard, fire-resistant coating that helps to insulate surrounding components. Insulation blankets are often used for industrial applications that require a removable or changeable shield, while more permanent coatings are used on automobile components and exhaust systems for long-term heat protection.

Common Heat Shield Applications

Heat shields can effectively insulate equipment in a variety of applications The type of heat shield you use depends largely on the way the heat is being transmitted. There are three typical types of heat transference that can be treated using heat shields:

  • Conductive heat, which is transmitted between objects through direct contact.
  • Convective heat, which is transmitted between solid objects and the movement of fluid or gas.
  • Radiant heat, in which the heat is generated from a solid source and radiates outward to indirectly affect objects in the surrounding area.

To ensure you have the correct barrier for your application, it is important to consider the way the heat travels through and away from your equipment. The most common heat treatments are dissipators, reflectors, and insulators. Each method uses a different operating principle to mitigate heat loss, and they can be used in conjunction to produce results tailored to the needs of specific applications.

Heat Dissipation

Heat dissipators consist of fabrics and materials that displace thermal energy, thereby reducing the amount of heat that passes through the shield and into the surrounding environment. They are typically used in specialty applications such as semiconductor equipment and electronics, where temperatures must be swiftly and efficiently regulated.

Heat Reflection

Reflective heat shields are the most commonly used heat mitigation method in industrial and mechanical applications. As the name implies, they act by reflecting heat from the surface of the material. It is particularly useful for protecting sensitive equipment and components that could be affected by the heat emitted by nearby generators, exhaust systems, and other heat-producing equipment.

Heat Insulation

Insulating heat shields serve a dual purpose. They keep heat close to the source and prevent it from escaping into the surrounding area. Heat insulation is particularly useful for equipment such as exhaust systems that require high operating temperatures for optimal performance, while still offering protection to the surrounding area.
