Thermal covers

Thermal sleeves / Thermalcovers for air freight and refrigerated transport

Thermal covers, also known as thermocovers, thermal covers or thermal blankets (sometimes written together as thermalcovers or thermalblankets), are flexible insulation covers that protect your goods from extreme temperature fluctuations and moisture. These insulation covers (popularly known as cooling blankets called) form a passive thermal barrier to keep refrigerated or heated cargo safely at temperature during transport and storage. Be it pharma products, fresh AGF products (potatoes, vegetables, fruit), fish and meat on a pallet, or temperature-sensitive chemicals, thermal cargo covers ensure reliable protection of your products. On this page, you can read how thermal sleeves contribute to food safety, product quality and a stable cold-chain of logistics.

Our thermal covers

What are thermal covers and why they are indispensable

Thermal covers are multilayer insulation blankets or covers that can be placed over pallets, roll containers or air cargo ULDs. They reflect heat and cold, providing a buffer against sudden temperature and moisture changes. They prevent your goods from getting too hot in the hot sun on the airport apron or, on the contrary, from cooling down too much in a cold storage warehouse. With a thermal cover - often called thermal cargo cover in air cargo - the temperature of the cargo remains much more constant. This is indispensable for temperature-sensitive products: think of medicines that need to stay within 2-8°C, or fresh foods that need to remain chilled for food safety. In addition, the cover also provides physical protection against weather conditions such as rain and condensation. In short, thermal covers bridge the vulnerable moments in logistics when active cooling is not always available and guarantee that product quality and safety are maintained.

Applications in practice

Air cargo (ULD, LD3, pallets)

Thermal sleeves are indispensable in air cargo. During ramp loading and unloading, temperature differences can be significant. Our ULD thermal blankets and thermal cargo covers protect pallets, LD3 containers and PMC units from heat, cold and moisture. This prevents damage to pharma, food or electronics, even with temperature differences in the cargo hold. We supply covers for all standard formats, such as EURO pallet thermal blankets and US pallet thermal covers.

Road transport & last-mile distribution
When a refrigerated truck is not available, thermal sleeves are an effective alternative. They keep products chilled for hours in standard transport trucks. They also enhance temperature stability in refrigerated trucks when sensitive goods or doors are opened frequently. In urban distribution, with short routes and limited refrigeration options, insulation covers provide reliable protection for products such as ice cream, meat or medicines.

Pharmaceutical industry
For medicines, vaccines and laboratory samples, thermal sleeves guarantee stable temperatures even during customs waits or delays. They prevent temperature alarm situations and protect against condensation. Combined with gel packs, they provide a passive, GDP-compliant solution for pharma logistics, without the need for expensive active cooling systems.

Food industry (AGF, fish, meat)
Thermalcovers are ideal for maintaining freshness and food safety. They prevent temperature fluctuations during AGF export, fish transport or chilled meat distribution. Thermalcovers help prevent spoilage and moisture problems, comply with HACCP requirements and guarantee top condition on arrival - even in case of air freight or road transport delays.

Chemical sector
Many chemicals are sensitive to temperature and moisture. Thermowells protect raw materials, coatings and solvents from harmful temperature effects or condensation. They are used for drums, IBCs and chemical pallets - also as a temporary solution when active cooling is missing or fails.

Customisation and range of thermal covers

No logistics challenge is the same. That is why Cooled Solutions delivers customised thermal sleeves and thermal covers, suitable for any type of cargo - from standard pallets to air cargo containers and roll containers.

What we offer:

  • Standard pallet sizes: Readily available in EURO pallet thermal blankets (120×80 cm) and US pallet thermal covers (120×100 cm), among others.

  • ULD thermal blankets: For all common air cargo containers such as LD3, LD6, PMC and more - perfect fit, without heat leaks.

  • Solutions for roll containers & specials: We also supply tailored insulation covers for non-standard carriers, dollies or machine parts.

  • Additional protection with under sheets: For full insulation on all sides, including the underside of your pallet or container.

  • Combination with gel packs or ice packs: Turn your thermo cover into a passive cooling system for 24-48 hours of reliable temperature control.

Each thermal cover is produced in our own facility and can be fully customised to your application: thicker material, UV-resistant outer layer, windows for labels or printed with your logo? We arrange it.

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.
