How to insulate container houses

Understanding the importance of insulation

The metal walls of containers are prone to absorbing heat in summer, leading to an increase in indoor temperature; In winter, they are prone to losing heat, making the indoor environment cold. Good insulation not only improves living comfort, but also reduces energy consumption and lowers electricity bills.

Material Analysis and Comparison

Insulating shipping container homes is essential for ensuring comfort and energy efficiency. Different insulation materials have their own characteristics and performance, and choosing the right material is crucial for achieving the best insulation effect.

 Insulation Material Analysis

1. Expanded Polystyrene (EPS) / Extruded Polystyrene (XPS)

Advantages:

• Lightweight, easy to cut and install.
• Good insulation performance.
• Relatively low cost.

Disadvantages:

• Poor fire resistance, requiring additional fireproofing treatment.
• Average resistance to moisture.

2. Rock Wool

Advantages:

• Excellent insulation and sound absorption performance.
• Good fire resistance, classified as non-combustible material A.
• Moisture resistant, suitable for humid environments.

Disadvantages:

• Heavier, requiring more labor for installation.
• Requires professional installation to prevent fiber inhalation.

3. Glass Wool

Advantages:

• Good insulation performance.
• Cost-effective.
• Recyclable.

Disadvantages:

• May cause skin and respiratory irritation.
• Average fire resistance.

4. Polyurethane Foam

Advantages:

• Extremely high insulation performance.
• Moisture resistant, suitable for humid environments.
• Can be sprayed or poured, forming a seamless insulation layer.

Disadvantages:

• Higher cost.
• Requires professional equipment and technicians for construction.

Material Comparison

Cost-Effectiveness

• Glass Wool and Expanded Polystyrene are usually less expensive, suitable for projects with a limited budget.

Insulation Performance

• Polyurethane Foam and Vacuum Insulation Panels offer the highest insulation performance, but at a correspondingly higher cost.

Fire Resistance

• Rock Wool is the best choice as it is a non-combustible material A.

Environmental Friendliness

• Cellulose is an environmentally friendly option as it is made from recycled materials.

Ease of Installation

• Expanded Polystyrene is the most convenient to install due to its light weight and ease of cutting.

Conclusion

When choosing insulation materials for shipping container homes, it is necessary to consider cost, insulation performance, fire resistance, environmental friendliness, and ease of installation comprehensively. For example, if the budget is limited, Expanded Polystyrene may be a good choice, but it requires additional fireproof measures. For projects pursuing the ultimate insulation performance, Polyurethane Foam or Vacuum Insulation Panels may be more suitable.

The final choice should be based on specific project needs, geographical location, and climate conditions. Before making a decision, it is recommended to consult professionals to ensure that the selected material can meet your insulation needs and comply with safety and environmental standards. With proper insulation treatment, shipping container homes can become an energy-saving, comfortable, and economical living space.
