How Our 40ft Container Liner Kits Reduce Condensation

Our reflective thermal insulation for 40ft containers prevents condensation and improves efficiency through:

  • Vapour Barrier Sealing – Prevents moisture ingress and condensation build-up.
  • Thermal Reflection – Reflective surfaces reduce radiant heat transfer.
  • Insulated Air Gaps – Create natural barriers to stabilise internal temperatures.

For maximum performance, we recommend insulating the entire container (walls, roof, and doors) rather than just the ceiling.

Key Benefits at a Glance

  • UK-made, high-performance reflective insulation
  • Proven condensation control for 40ft containers
  • DIY installation with all materials included
  • Suitable for storage, transit, or conversions

Container Liner Insulation Data Sheet

Container Liners – Quick & Easy Installation

Our container liners are designed for effortless installation and come in two insulation options.

Our best-selling ThermaPack Ultra Double offers a highly effective radiant barrier at a competitive price. Each kit includes made-to-measure rolls with adhesive backing for easy positioning.

Performance Comparison:
🔹 ThermaPack Ultra Double (Best-Seller)
● Ideal for storage containers, maintaining a stable internal temperature.
● Made from true aluminum foil for superior insulation.
● 4mm thick, yet equivalent to 55mm of polystyrene in performance.

🔹 EcoQuilt (Highest Performance)
● Best for container conversions into offices, living spaces, or temperature-sensitive storage.
● Features 2 layers of wadding-laminated foil and 3 layers of radiant foil, separated by wadding.
● 15mm thick, yet performs like 75mm of polystyrene.

Fixing Instructions – Container Liner Insulation Kit
Preparation:

● Ensure the walls, roof, and floor are dry, clean, and free of grease or dust before
installation.

Installation Steps:
1. Insulating the Walls:
○ Start with one wall section, beginning at the center of the back wall and working forward to the middle of the front door.
○ Repeat with the second wall section, again starting from the center of the back wall.

2. Insulating the Roof:
○ The roof insulation comes in two rolls for easier handling. Install them after
completing the walls.

3. Insulating the Floor (if required):
○ Once the walls and roof are in place, apply insulation to the floor.
4. Sealing Joints & Edges:
○ Use the included silver foil joining tape to fully seal all edges and joints. Incomplete sealing can allow moisture to pass through, leading to condensation.
○ Use a strong brush to firmly secure the insulation to the walls.

IMPORTANT:
❌ Do not adhere the membrane into vertical apertures—it should lie flat against the wall. This ensures maximum thermal efficiency.

FAQ

What is a 40ft container insulation kit?

A 40ft container insulation kit is a pre-cut thermal insulation system designed to fit standard 40-foot shipping containers. It is used to line the internal surfaces of the container to help regulate internal temperature and reduce heat transfer.

This provides thermal protection for temperature-sensitive cargo during long-distance transport and also helps prevent condensation build-up during storage.

Can 40ft shipping container insulation kits handle extreme hot and cold temperatures?

Yes, high-quality 40ft insulated container liners are designed to perform in extreme hot and cold environments.

They work by reducing radiant heat transfer, helping to keep heat out in high temperatures and retain warmth in colder conditions. This makes them suitable for demanding logistics environments and temperature-sensitive supply chains.

Are 40ft insulation kits suitable for international shipping?

Absolutely. 40ft container insulation kits are widely used in international and export shipping for industries such as food, pharmaceuticals, and industrial goods.

They help stabilise internal container conditions during long transit times, where cargo may be exposed to varying climates, humidity, and temperature fluctuations.

What materials are used in 40ft shipping container insulation kits?

Most 40ft container insulation kits are manufactured using high-performance thermal materials such as reflective aluminium foil, multi-layer bubble insulation, and reinforced laminated barriers.

These materials work together to reflect radiant heat, reduce thermal transfer, and improve overall energy efficiency inside the container.

How long can cargo stay protected in a 40ft insulated container?

The level of protection depends on factors such as insulation thickness, external climate conditions, and whether active cooling or heating systems are used.

In many cases, a 40ft insulated container can help maintain more stable internal temperatures for several days during transit or storage, reducing the risk of temperature-related damage.
