People recognize container buildings and houses as temporary structures for their eco-friendliness, convenience, low cost, and quick construction. In cold regions, builders prioritize insulation. Many choose polystyrene foam board (EPS) as a popular and affordable insulation material due to its good thermal performance. Workers find it lightweight, easy to cut, and can attach it directly to container walls. However, its limited strength and fire resistance make it less suitable for projects requiring high fire resistance.
Extruded polystyrene foam board (XPS) offers better insulation. Made through a special process, it has a dense structure, lower thermal conductivity, and superior insulation. XPS is strong, resistant to compression, and handles weight and impact well. Its low water absorption makes it ideal for humid environments.
Polyurethane foam is highly efficient, with very low thermal conductivity and excellent integrity. Sprayed on-site, it fits container walls perfectly, filling gaps and creating a seamless insulation layer. This prevents thermal bridges and ensures long-lasting insulation. However, it’s more expensive and requires precise construction.
Weifang Carter designed the cold-resistant box house for extreme cold environments, making it suitable for high-altitude regions with temperatures as low as -30°C. Indoor heating maintains a comfortable 20°C. They staged the insulation based on thermal performance calculations to ensure reliable performance in various low-temperature conditions.
