What materials are commonly used in the construction of flat pack container houses?

Flat pack container houses are constructed using a combination of durable and lightweight materials to ensure strength, insulation, and ease of transport. The most commonly used materials include:  

1. Steel Frame – Typically made from galvanized or stainless steel for structural support and durability. It provides resistance to corrosion, weather, and external forces.  

2. Wall Panels – Usually made of sandwich panels consisting of:  

  - Steel sheets + insulation core (e.g., polyurethane (PU), polystyrene (EPS), or rock wool for fire resistance and insulation).  

  - Some high-end models use fiber cement boards or aluminum composite panels for extra durability.  

3. Flooring – Can be made of:  

  - Plywood or fiber cement board (for strength and resistance to moisture).  

  - Vinyl, laminate, or tile finishes (for aesthetics and comfort).  

4. Roofing – Often constructed from corrugated steel sheets with additional insulation layers to regulate temperature and prevent leaks.  

5. Windows & Doors –  

  - Aluminum or PVC-framed windows with glass panels for insulation.  

  - Steel or composite doors for security and durability.  

6. Insulation Materials – Essential for temperature control, including:  

  - EPS (Expanded Polystyrene) – Lightweight and cost-effective.  

  - PU (Polyurethane) – Provides better thermal insulation.  

  - Rock wool – Excellent for fire resistance and soundproofing.  

7. Electrical & Plumbing Components – Pre-installed in many models, using PVC pipes, copper wiring, and LED lighting for efficiency.  

These materials are chosen to balance strength, insulation, portability, and affordability, making flat pack container houses a practical housing solution.
