Our materials feature excellent thermal insulation and fire-retardant properties, perfectly compatible with water-cooled refrigeration systems, significantly reducing cooling loss. To help enterprises build green and energy-efficient cold storage, we provide the following price details for water-cooled cold storage insulation materials:
Cold storage insulation materials are the core of the cold chain warehouse envelope structure, directly determining the thermal insulation effect, moisture resistance, and long-term energy consumption costs of the cold storage. Currently, the mainstream cold storage insulation materials on the market mainly fall into the following categories:
1. Polyurethane (PU/PIR) Insulation Panels
Polyurethane is currently the most widely used and best-performing mainstream insulation material in the cold storage industry. It typically adopts a "sandwich" structure, with a high-density rigid polyurethane foam core in the middle, and metal facings such as color-coated steel sheets, stainless steel sheets, or embossed aluminum sheets on both sides. Its thermal conductivity is low (usually between 0.018~0.024 W/(m·K)), and its closed-cell rate exceeds 95%. It not only provides excellent thermal insulation but also offers superior waterproof and moisture-proof performance, effectively preventing condensation inside the cold storage. Moreover, high-quality polyurethane materials can meet the B1 flame-retardant standard, offering high fire resistance.
2. Polystyrene (EPS/XPS) Insulation Panels
Polystyrene is divided into EPS (expanded polystyrene) and XPS (extruded polystyrene). The advantage of these materials lies in their relatively affordable price and good moisture resistance, making them commonly used in small fresh-keeping warehouses with limited budgets or temporary cold storage. However, their thermal conductivity is relatively higher (0.030~0.035 W/(m·K)), resulting in inferior insulation performance compared to polyurethane. Additionally, their fire-retardant properties are poor (mostly B2 grade), and they are prone to deformation under extreme temperature differences over long-term use. Therefore, they are often used as auxiliary materials or for low-end cold storage envelope solutions.
3. Rock Wool and Glass Wool
Rock wool and glass wool are inorganic insulation materials. Their greatest advantage is excellent fire resistance, achieving Class A non-combustible standards, making them highly suitable for pharmaceutical cold storage and chemical explosion-proof cold storage with stringent fire protection requirements. However, these materials have relatively high thermal conductivity (0.035~0.045 W/(m·K)), resulting in poorer insulation performance. They are also heavy and have high water absorption rates, and when used alone, they are prone to moisture absorption leading to insulation failure. Therefore, in practical engineering, they are often combined with materials like polyurethane to balance fire resistance and thermal insulation.
4. On-site Spray Polyurethane Foam
In addition to prefabricated panels, on-site spraying is also an important process for cold storage insulation. It involves spraying polyurethane foam raw liquid directly onto walls or roofs, which instantly foams and forms. The greatest advantage of this process is its ability to create a continuous, seamless insulation layer that conforms to various irregular structures, fundamentally eliminating the "thermal bridge effect" caused by panel joint gaps, resulting in excellent overall air tightness and insulation performance.
In summary, the selection of cold storage insulation materials requires a comprehensive evaluation based on specific temperature zone requirements, fire protection standards, and budget. Among them, polyurethane insulation panels are the absolute mainstream due to their outstanding thermal insulation and moisture resistance; rock wool is a necessity for high-standard fire protection scenarios; and on-site spraying provides a seamless insulation solution for cold storage with complex structures.
