How Our 20ft Container Liner Kits Work

Our reflective thermal insulation for 20ft shipping containers prevents condensation and heat transfer through:

  • Vapour Barrier Layer: Stops moisture ingress.
  • Thermal Reflection: Reflects radiant heat away from internal surfaces.
  • Insulated Air Gap: Improves temperature stability and energy efficiency.

For best results, insulate the entire container, not just the roof.

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 20ft container insulation kit?

A 20ft container insulation kit is a pre-cut thermal insulation system designed specifically to fit standard 20-foot shipping containers. It is used to line the internal walls, roof, and doors of the container to reduce heat transfer.

This helps maintain a more stable internal temperature, protecting temperature-sensitive goods during transport, export shipping, or long-term storage.

Can I use the kit for cold shipments?

Yes, a 20ft container insulation kit is suitable for cold chain applications. It helps reduce heat gain in hot climates and minimise heat loss in cold environments, making it ideal for chilled, frozen, or temperature-sensitive cargo.

This makes it widely used in logistics, where maintaining a consistent internal environment is critical.

How easy is it to install a 20ft insulation kit?

Most 20ft insulated container liners are designed for quick and straightforward installation, even without specialist tools. They are typically supplied as pre-cut panels with adhesive backing, hook-and-loop fixings, or simple fastening systems.

This allows for fast fitting inside empty containers, reducing downtime and labour costs.

Are these kits suitable for food or pharmaceuticals?

Yes, 20ft container insulation kits are commonly used in cold chain logistics for food, beverage, and pharmaceutical transport. They help protect perishable and temperature-sensitive products from external temperature fluctuations during shipping and storage.

This supports product quality, safety, and compliance with temperature-controlled supply chain requirements.

Can the kit be customised?

Yes, container insulation kits can often be customised to suit specific shipping and storage requirements. Options may include different insulation thicknesses, thermal performance levels, and material types depending on the application.

Custom sizing and accessories can also be added to optimise performance for specialist cold chain or industrial use.
