Amazing Benefits of Cryogenic Perlite for Cold Storage

Cryogenic perlite is one of the world’s most under-appreciated insulation materials. Consisting of millions of tiny glass bubbles containing trapped air, it helps to keep our energy and essential gas infrastructure operating efficiently and delivering the resources our modern society depends on for sustaining life.

Cryogenic perlite blocks the transfer of heat and to keep things like liquified natural gas (LNG), hydrogen, nitrogen, oxygen and more, super cold and in denser liquid form for storage and transfer.

This article will tell you what makes cryogenic perlite special. We will see how it is used and how it helps cold storage work better.

What is Cryogenic Perlite?

Benefits of Cryogenic Perlite Image

Cryogenic perlite is very good at keeping things cold. It is primarily used to insulate double-wall cryogenic grade storage tanks and “cold-boxes”, containers for keeping essential equipment and pipes cold.

Benefits of Cryogenic Perlite

Expanded perlite is great for keeping things cold because it contains a lot of trapped air in each glass bubble that stops heat from passing through it. Its special properties make it an excellent choice for insulation.

Great Insulation

Cryogenic perlite is great at stopping heat and keeping storage tanks and containers cold. It works well for extreme temperatures, because being mineral-based, it is not susceptible to very high temperatures or very low temperatures. This makes it perfect for industries that need to keep things either extremely hot or cold.


Cryogenic perlite is very lightweight. This puts less pressure on the walls and floor of storage structures. Because it’s so lightweight, it can be blown into cavities and tanks even tens of meters in height.


Cryogenic perlite does not catch fire or react with chemicals, which makes it very safe to work around. This helps protect stored items, and keeps workers safe on the job.


If installed properly, cryogenic perlite will provide years of lasting service. It does not degrade over time, and is easy to remove and replace when maintenance on a storage vessel is due.

Uses of Cryogenic Perlite

Cryogenic perlite is used in many ways. It helps keep things very cold in storage tanks, pipes, and containers. Industries like energy, medicine, and science rely on it to keep their essential services up and running, and operating efficiently.

LNG, Liquid Hydrogen, LOX Tanks

Cryogenic perlite is used to insulate tanks that store liquefied natural gas (LNG), hydrogen, and liquid oxygen (LOX). These substances are pressurized for storage and are therefore stored very cold. They need to be kept cold to keep from expanding and boiling off. Perlite helps keep them cold without the need for additional energy, making it an essential choice from a sustainability standpoint.

Other industries

Other industries, from the microchip industry to medicine, biotech, pharmaceuticals, agricultural fertilizers and more rely on specialized gasses and storage. Cryogenic grade perlite is used to insulate tanks and equipment and keep things at a stable temperature.

Installing and Maintaining Cryogenic Perlite


Cryogenic perlite installation requires specialized equipment and training. It is usually blown in between tank walls or into cold boxes using pneumatic equipment. Sometimes, this involves expanding the perlite on-site using specialized mobile expanders. At other times, the insulation is expanded off-site and delivered to the job-site in bulk super sacks or in a bulk tanker.


Cryogenic perlite needs very little maintenance, but it is important to keep it dry to ensure it continues to provide value as an insulator. Leaks in piping, or an abnormal amount of condensation inside the insulation cavity and reduce the effectiveness of the perlite insulation. In this case, the insulation will need to be removed from the containment area, any pipes and leaks repaired, and finally the insulation needs to be replaced with new if it cannot be reused.

Some settling may also be expected with larger volume tanks or tall columns after the initial filling. This can require a “top-off” installation after a settling period. Inspection of the exterior of the tank using thermal imaging equipment will reveal cold spots on the outer tank where there is not enough insulation. Top-off may occur several times over the lifetime of the tank as vibrations in the tank and system while in service can cause settling over time. Thermal performance of the tank should be monitored at periodic intervals and top-offs scheduled as needed.

Innovations in Cryogenic Perlite

Manufacturers are finding ways of making perlite more efficiently.

Better Production

New methods have improved the efficiency of how perlite is produced. New furnace technology means we can lower the embodied energy used to make cryogenic grade perlite.

How is Cryogenic Perlite Delivered?

Cryogenic Grade perlite comes in a number of different packaging sizes and delivery methods.

One method of transporting cryogenic perlite is in bulk trailers, which use pressurized air (pneumatics) to convey the insulation into the containment vessel on the jobsite. This can be an efficient and popular delivery method when it is available.

Other common packaging methods are bags and bulk super sacks. Bags and super sacks are palletized which means they can be handled by forklifts and delivered in typical freight trucks or containers.

Bags are a practical packaging unit for small jobs and those where individual workers will need to carry bags up stairs to an access port, or where access is tight.

Bulk super sacks are popular where a large volume of insulation needs to be delivered and filled in a shorter amount of time, and where there is the equipment available to handle the larger package size (such as a crane or hoist).

As always it is important to keep the insulation dry at all times which means it is important to store the insulation in a dry, covered location, and to schedule maintenance during dry weather.
