High Temperature Insulation
If you work with equipment like vessels, boilers or industrial ovens, you know the appliance and the area around it can get hot. That’s why proper performance and safety are top of mind when it comes to elevated temperature insulation. It’s designed to help with efficient operation, reduce overall operating costs and even provide protection.

The Importance of Elevated Temperature Insulation
There’s a wide variety of high temperature equipment needing insulation — furnaces, boilers, precipitators, ducts, H-bar systems, vessels, marine equipment, industrial ovens and more.

Efficiency

Temperature consistency is crucial. To effectively do its job, high temperature equipment needs the right insulation. Adding insulation delivers process control by maintaining the temperature throughout. This can lead to greater operating efficiencies and reduced energy loss — which, in turn, can lead to reduced operating costs.

Condensation Control

When temperatures aren’t maintained, condensation can form. This can lead to pooling water. Proper insulation can help minimize the chance of condensation building up.

Sound Control

During operation, pipes and equipment can create vibrations or even banging sounds. Fiberglass insulation can help absorb these excessive operational noises.

Safety

Elevated temperature pipe and equipment can give off such high heat, it’s unsafe to come in contact with and could overheat the environment it’s in. High temperature insulation can help regulate these temperatures, providing a protective layer over the surface by minimizing heat transfer. It can also provide fire protection and reduce the spread of flames.

Pro Tips for Adding High Temp. Insulation

Though, rockwool has traditionally been used for high temperature insulation, fiberglass has proved itself as an efficient performer. It’s tough and durable to provide the necessary thermal performance. Yet, the flexibility of it allows for easy fabrication so you can achieve the right fit, even for irregular spaces. Look for fiberglass insulation with a facing that leaves fewer wrinkles and easily wipes clean. This will give the space a smooth, finished appearance.
