High-Performance Thermal Insulation

Thermal insulation performance depends on reducing heat transfer due to thermal conduction, convection, or radiation. All Insulon® parts use our patented deep vacuum technology to drastically reduce convective and conductive heat flow; for the most demanding applications, our engineers include our proprietary multi-layer insulation to reduce radiation heat transfer. Insulon® helps you concentrate thermal energy where you want it, often resulting in reduced energy demands and consumption.

How does MLI reduce radiation heat transfer?
Multi-layer insulation reduces radiation heat transfer by reflecting radiation back towards the source

Vacuum Super Insulation with MLI

For even higher thermal performance, particularly at high temperatures, reducing radiation heat transfer is key. To create vacuum super insulation, we install our proprietary, high-density multi-layer insulation (MLI) inside the vacuum space. MLI uses highly reflective materials to drastically reduce radiation heat transfer. Like all Insulon® components, our Insulon® + MLI packages can be designed to operate in environments up to 1000°C.

Engineering & Manufacturing

We engineer ultra-thin, high-performance vacuum insulation to enhance your product or system functioning. Our goal is to maximize thermal performance while consuming minimal space. Custom-designed solutions can help bring out the best in your application by improving thermal efficiency, streamlining packaging, and optimizing for longevity in your system.

​Our engineers work with you to develop a design that fulfills thermal, geometric, and structural requirements. Once designs are completed, we start building and testing your custom prototypes at our R&D facility. When it’s time for the next step, our manufacturing team puts together semi- or fully-automated cells for rapid, high-volume production.

​The end result? An enhanced thermal system for more effective and efficient performance.

Custom designed solutions

Custom-designed thermal solutions can help your product stand out against the competition. Our goal is to deliver precise thermal enhancements that improve the overall performance of your product. Our engineers take a holistic approach to design, considering everything from component-level parameters to system-level parameters. Every feature of an Insulon® vacuum insulated part is custom-designed to your specifications — down to the very last millimeter.

Ultra-thin insulation

Thin thermal insulation with a high R-value is of paramount importance to space-constrained applications. Our custom-designed vacuum insulation delivers thermal solutions in a compact package. With an overall thickness as low as 0.25mm, our parts can be used to insulate needles. Our low profile design can help your product save space, maintain a sleek profile, and reduce overall packaging requirements — without sacrificing thermal performance.

High mechanical strength

Durable components built with high-strength materials. Our materials include metals such as stainless steel, Inconel, and other alloys, making Insulon® vacuum insulation ideal for challenging physical environments. If you need a component with specific mechanical properties, let us know. High-pressure environment? No problem. Dealing with vibration? We can help. Our robust components can be built to withstand a variety of mechanical stresses.

High-temperature insulation

Vacuum insulation has traditionally been used exclusively for cryogenic applications. Our proprietary Insulon® Technology creates ultra-thin, high-temperature vacuum insulation for applications up to 1000°C. For the most demanding applications, reducing radiation heat transfer is key. Our most advanced Insulon® parts may also include our proprietary multi-layer insulation for even greater high-temperature thermal performance.

Simplified assembly

With many conventional materials, you have to do the installation yourself. This might mean spraying foam, clamping down blankets, or cutting, wrapping, and taping pyrogel in hard-to-reach places. These tedious installation processes can slow down your manufacturing process, costing you time and money. Insulon® offers an alternative product — delivered as a preformed component built to spec, Insulon® is ready to be seamlessly integrated into your assembly.

Proprietary technology

No one else uses our patented technology found in every Insulon® part. From our advanced vacuum insulation technology to our high density, high-temperature MLI, all of our proprietary technology is designed in-house — and nowhere else. Our engineers are constantly making advancements in thermal technology, and we take pride in delivering one-of-a-kind solutions to each and every customer.
