What is Insulon® Technology?

Insulon® is a patented vacuum insulation technology that is used to create high performance thermal insulation components. The most advanced parts may also include proprietary high temperature multilayer insulation. Effective in both cryogenic and high temperature systems, Insulon® can operate in thermal environments ranging from -270°C to 1000°C.

What insulation materials are used to make Insulon®?

Stainless steel, Inconel, and other alloys are used to build Insulon®. Insulation materials are selected according to the needs of individual applications and can be selected to fulfill food grade or medical grade material requirements.

What are R-values and U-values?

R-values are used to measure an insulation material’s thermal resistance. Insulation materials with higher R-values can reduce heat transfer more effectively. U-values are used to measure thermal transmittance. Insulation systems with lower U-values have a lower rate of thermal transmittance than those with a higher U-value.

What is the R-value for Insulon®?

Our engineers custom design Insulon® to suit individual applications. This means that the thermal resistance, or R-value, varies with each part. Insulation performance can be adjusted using various parameters including dimensions and material selection. Most Insulon® parts have an overall wall thickness in the order of millimeters and can deliver hundreds of degrees of temperature difference.

Is Insulon® a thermal barrier coating (TBC)?

No, Insulon® is not a thermal barrier coating. Insulon® is manufactured in standalone components including tubes, pipes, cans, containers, flasks, and custom geometries. If you have an existing stainless steel or other metal structure, an Insulon® lining may be installed inside the walls. While not a coating, Insulon® can be as thin as 0.25 mm.

How long does Insulon® last?

When custom-designing Insulon® parts, our engineers carefully consider the longevity requirements of your application including duration of use, thermal cycling, exposure to thermal shock, and performance requirements. We focus on life cycle optimization to ensure the greatest ROI for your company.

Is Insulon® food-grade insulation?

Yes, Insulon® can be designed with food-grade insulation materials. Our stainless steel tubes and pipes are ideal for food-grade pipe insulation.

Is Insulon® medical-grade insulation?

Yes, Insulon® can be designed for medical and surgical applications such as thermal ablation therapies. Manufactured from stainless steel, Insulon® parts are easily sterilized.

Can components be welded onto Insulon® parts?

It is possible for components to be welded onto Insulon® parts, depending on the application. If your application requires a flange or mounting bracket, let us know and we can supply it as a completed assembly.

Are Insulon® parts DFARS compliant?

Yes, Insulon® parts can be manufactured to be DFARS compliant.

How long has Concept Group LLC been in business?

Founded in 1970, Concept Group LLC (formerly Concept Group Inc.) has been in business for over 50 years.

Can Concept Group fulfill high volume orders?

Yes, Concept Group uses state of the art automation technology to manufacture millions of parts per year with high precision and rigorous quality control.

Where are Concept Group’s products designed and manufactured?

Concept Group’s products, including Insulon® parts and our glass to metal seals, are designed and manufactured in the United States.

Does Concept Group ship internationally?

Yes, Concept Group has many international business relationships. We look forward to working with you regardless of your location.

What kind of glass to metal seals does Concept Group manufacture?

We manufacture stainless steel compression glass to metal seals.
