Insulation Boards for Container-Renovated Houses

Common insulation board materials for container-renovated houses include polystyrene boards, polyurethane foam boards, and rock wool boards. Prices vary significantly depending on the material type and specifications, and attention should be paid to sealing and structural stability during construction.

Types and Characteristics of Insulation Materials

Insulation boards for container-renovated houses need to have low thermal conductivity and good thermal insulation properties. Common materials include:

1. Polystyrene Boards: Made from polystyrene, these boards have low thermal conductivity and are relatively affordable, but their fire resistance is generally average, making them suitable for scenarios where cost is sensitive and fire resistance requirements are not high.
2. Polyurethane Foam Boards: Their closed-cell structure provides excellent thermal insulation performance, along with a certain degree of strength and water resistance. They are often used in exterior wall insulation and decorative integrated panels, with a medium price range (e.g., ¥24.7 per square meter).
3. Rock Wool Boards: Made from basalt, these boards have a Class A fire rating, are resistant to high temperatures, and offer good sound absorption and noise reduction effects. However, they are relatively expensive (e.g., ¥95.0 per square meter) and are suitable for places with strict fire resistance requirements (such as temporary construction site housing).

Price Range of Insulation Boards

Market prices vary significantly depending on the material, thickness, and function:

• Economy Type: Polyurethane sandwich panels (¥10.92 per square meter), exterior wall insulation and decorative integrated panels (¥14.5 per square meter), suitable for projects with limited budgets.
• Mid-Range Type: Color-steel core phenolic insulation panels (¥40.0 per piece), metal carved panels (¥24.7 per square meter), balancing performance and cost.
• High-End Type: Rock wool color-steel houses (¥122.55 per square meter), exported integrated housing SIP panels (¥150.0 per square meter), with high fire ratings, suitable for long-term use or high-standard buildings.

Construction Points

1. Installation Location: Insulation boards can be attached to the exterior wall surface or interior walls of the container, forming a continuous thermal insulation layer and reducing thermal bridge effects.
2. Sealing Treatment: Special sealants or waterproof strips should be used at the joints to prevent air infiltration and degradation of thermal insulation performance.
3. Structural Reinforcement: Mechanical fastening or adhesives should be used to connect the insulation boards to the container frame, ensuring they do not detach under extreme weather conditions or vibrations.
4. Fire Prevention Measures: If flammable materials such as polystyrene boards are used, fire barriers or fire-resistant coatings should be added to comply with building code requirements.

Selection Recommendations

Choose materials based on the usage scenario: For temporary housing, polyurethane boards or phenolic boards (low cost, quick installation) are preferred; for long-term residence or commercial use, rock wool boards (fire-resistant, durable) are recommended. Before construction, calculate material costs, transportation expenses, and labor costs to comprehensively evaluate cost-effectiveness.
