Thermal sleeves / Thermalcovers for air freight and refrigerated shipping
Thermal covers, also known as thermalcovers, thermal covers or thermal blankets, are flexible insulation covers that protect goods from temperature fluctuations and moisture during transport and storage.
Cooled Solutions produces thermal sleeves entirely in-house, allowing us to move quickly, deliver customised solutions and guarantee consistent quality for professional applications within logistics and air cargo.
Our thermal sleeves form a passive thermal barrier and are widely used for refrigerated shipping of products on pallets and ULDs (Unit Load Devices). They help protect temperature-sensitive goods from external influences during transport and handling.
Thermal sleeves are widely used within logistics and air cargo, where temperature control is essential. Think of applications in the pharmaceutical sector, fresh AGF products, fish and meat on pallets or temperature-sensitive chemicals. In all these situations, thermal cargo covers contribute to maintaining product quality and a stable cold chain.

- ✓ Customisation possible
- ✓ Fast delivery times
- ✓ Suitable for air cargo and logistics
- ✓ Reliable protection within the cold chain
How do thermal covers work?
Thermosheets work as a passive insulation layer around a pallet, ULD or cargo. They do not actively cool, but slow down temperature changes by external influences such as heat, cold and air currents.
Temperature, sun, wind and moisture affect your cargo during transport and storage.
The thermal cover limits heat transfer and protects against rapid temperature changes.
Products stay within a safe temperature for longer during logistics processes.
What determines the performance of a thermal cover?
- Initial charge temperature
- Duration of transport and transhipment
- Outdoor temperature and conditions
- Use of gel packs or ice packs
- How well the cover fits around the pallet or ULD
Important to know
- Thermowells work passively and do not actively cool
- They slow down temperature change, but do not stop it completely
- Ideal during transhipment, storage and transport without continuous cooling
- Often combined with gel packs for additional temperature control








Applications of thermal covers
Thermal sleeves are used in practice for:
- air cargo of pharmaceutical products (GDP logistics)
- refrigerated dispatch of meat, fish and meals
- transport of AGF products
- protection of pallets during storage and transport
Standard thermal sleeves and customised solutions
Most thermal covers are used in standard formats for pallets and air cargo, such as EURO pallet (120×80 cm) and US pallet (120×100 cm). These can be used immediately and fit perfectly into common logistics processes.
For air cargo, we also supply thermal covers for ULDs such as LD3, LD6 and PMC units. These thermal covers protect your cargo from temperature fluctuations during transport and handling.
Do you have a non-standard application? Then thermal covers can also be tailored to specific dimensions, such as roll containers or special loads.
Thanks to our own production, we deliver quickly and flexibly, both for standard solutions and custom-made solutions within the cold chain.
Applications of thermal covers
Thermal sleeves are used in various sectors where temperature control is essential. Below is an overview of the most common practical applications.
Air cargo (ULD, LD3 and pallets)
Thermal covers are indispensable within air cargo. Large temperature differences often occur during ramp loading and unloading. Thermalcovers protect pallets, LD3 containers and ULDs against heat, cold and moisture. This prevents damage to pharmaceutical products, food and electronics and ensures a more stable temperature throughout the transport process.
Road transport and last-mile distribution
When a refrigerated truck is not available, thermal sleeves offer a practical solution. They help keep products at temperature for longer in standard transport trucks. They also improve temperature stability in refrigerated trucks during frequent door movements. Ideal for city distribution and short trips where temperature loss is a risk.
Pharmaceutical industry
Within pharmaceutical logistics, temperature control is crucial. Thermal sleeves protect medicines, vaccines and laboratory samples from temperature fluctuations and condensation. Combined with gel packs, they provide a reliable passive solution for transport without active cooling.
Food industry (AGF, fish and meat)
For transporting fresh produce such as vegetables, fruit, fish and meat, thermal sleeves are an effective solution to preserve quality and freshness. They reduce temperature fluctuations and help prevent spoilage and moisture problems during transport and storage.
Chemical sector
Many chemical products are sensitive to temperature and moisture. Thermal covers protect raw materials, coatings and liquids from external influences. They are used in transport of drums, IBCs and pallets, both as a standard solution and as temporary protection in case of failure of active cooling.

Benefits of thermal covers
Optimal temperature control: A thermal sleeve keeps products within the desired temperature range, even in extreme heat or cold. It significantly slows temperature rise or fall, reducing the impact of temperature fluctuations (e.g. due to sunlight or night-time cold). Your goods stay at the right temperature for longer, preventing spoilage and loss of quality.
Protection against moisture and condensation: Thermocovers not only protect against temperature, but also against moisture. They act as a barrier against rain and high humidity. In addition, they help prevent condensation on your products during rapid transitions from cold to warm environments (or vice versa). This minimises damage caused by moisture, such as mould on vegetables or ice crystal formation on frozen food.
Durable and reusable: Cooled Solutions supplies high-quality thermal covers made of sturdy, tear-resistant materials. Our covers are reusable and designed for long-term use, which is both durable and cost-saving. Unlike single-use film or boxes, these thermal blankets multiple trips without sacrificing effectiveness.
Simple to use: Our insulation covers are lightweight, flexible and can be installed within minutes. You can easily slide them over a pallet load or wrap them around a container. Thanks to clever designs - such as Velcro fasteners or zips - the covers fit snugly and stay firmly in place, even during handling. No hassle with complex installations: thermocovers can be quickly deployed by your staff.
No energy required (passive cooling): Thermo sleeves offer passive cooling, meaning they consume no power or fuel to cool. No active coolers or cooling motors are required. This makes them ideal in places or at times when no cooling system is available. In addition, you save on energy costs and are less dependent on refrigerated trucks or generators. This flexibility can be a big advantage in logistics planning.
Frequently asked questions about thermal covers
Yes, thermal covers are widely used within air cargo (air cargo) to protect temperature-sensitive goods during transport. They are applied to pallets and ULDs such as LD3 containers and PMC units.
Thermal sleeves are a passive solution and help reduce temperature differences during transport. The effect depends on factors such as outside temperature, duration of transport and type of load.
A thermal sleeve is a passive solution and operates without power or refrigeration equipment. Active cooling uses, for example, refrigerated containers or reefers. Thermowalls are often used as additional protection or when active cooling is not available.
Yes, thermal sleeves are used for refrigerated shipping of products such as meat, fish and AGF. They help reduce temperature fluctuations during transport.
Yes, thermal sleeves are often combined with gel packs or other refrigerants to better control temperature during transport.
Thermowells are used for temperature-sensitive products such as medicines and pharmaceuticals, meat, fish and meals, AGF products and chemical raw materials.
Thermal sleeves are used when products need to be protected from temperature differences during transport, for example in air cargo, storage or when active cooling is not available.
