In the fields of construction and industrial insulation, panel thickness is one of the core parameters determining performance and cost. Different application scenarios have varying requirements for the insulation, structural, and fire safety properties of sandwich panels, leading to the development of multiple standard thickness specifications. As a leading global building panel manufacturer and exporter, ZHUOZHU leverages extensive production experience and professional expertise to provide customers with a full range of thickness options from 16mm to 100mm.
Cool Room Panel Thickness Specifications and Application Analysis
As the core building material for professional cold chain facilities, the thickness selection of Cool Room Panels directly impacts the stability of internal temperature and energy efficiency. Compared to standard metal sandwich panels, cool room panels feature more precise joint designs and surface treatments that must comply with food hygiene standards.
Standard Thickness Specifications: 25mm, 50mm, 100mm
- 25mm Cool Room Panel
- Performance Characteristics: An economical thin panel with limited insulation performance (R-value approx. 0.9-1.1 m²·K/W).
- Typical Applications:
- Short-term storage high-temperature rooms (+10°C to +15°C), such as certain fruit and vegetable pre-cooling areas.
- Used as partition walls or ceilings within cold storage for areas with less stringent temperature zoning requirements.
- Packaging areas or anterooms with low insulation demands.
- ZHUOZHU Solution: We can provide 25mm thin panels with a PIR core, achieving the best insulation within a limited thickness while ensuring joint tightness.
- 50mm Cool Room Panel
- Performance Characteristics: The most widely used medium-thickness specification, balancing performance and cost. When using a PIR core, the R-value can reach approximately 1.8-2.2 m²·K/W.
- Typical Applications:
- Refrigerated warehouses (0°C to +8°C), e.g., for beverages, dairy products storage.
- Low-temperature sorting areas, logistics transit cold storage.
- Small and medium-sized cold chain facilities with energy consumption control requirements.
- ZHUOZHU Solution: As a professional cool room panel supplier, we recommend 50mm as the standard starting thickness for most commercial refrigeration projects and provide standing seam systems with cold bridge prevention design.
- 100mm Cool Room Panel
- Performance Characteristics: A high-performance specification for medium-to-low temperature environments. R-value can reach approx. 3.5-4.5 m²·K/W, effectively reducing heat loss and ensuring temperature stability.
- Typical Applications:
- Freezer warehouses (-18°C to -25°C), e.g., for long-term storage of meat, seafood.
- Blast freezing tunnels, low-temperature processing workshops.
- Storage for high-value products sensitive to temperature fluctuations.
- ZHUOZHU Solution: Our high-density PIR core 100mm panels place special emphasis on core material uniformity and overall strength, ensuring structural stability for long-term use in low temperatures. For ultra-low temperature needs, we can also provide thicker custom solutions.
Selection Key Point: The lower the design temperature of the cold room, the greater the required panel thickness and insulation performance. Initial investment must be balanced with long-term operational energy costs.
Metal Sandwich Panel Thickness Specifications and Application Analysis
Universal metal sandwich panels are widely used in the walls and roofs of industrial and commercial buildings. Their thickness selection is more diverse, requiring consideration of insulation, structural span, and cost.
Standard Thickness Specifications: 25mm, 30mm, 40mm, 50mm, 100mm
- 25mm & 30mm Thin Panels
- Application Scenarios: Primarily used for indoor partition walls, ceilings, equipment house roofs, etc., where insulation requirements are minimal. Can also serve as interior partitions within cleanroom panel systems.
- ZHUOZHU Products: Often use EPS or thin rock wool cores, offering economy and practicality.
- 40mm & 50mm Standard Panels
- Application Scenarios: This is the most mainstream thickness choice for walls and roofs of industrial plants and warehouses. 50mm sandwich panels can significantly improve building energy efficiency, complying with energy codes in many regions.
- ZHUOZHU Advantage: We offer the most comprehensive core material choices (EPS, PIR, Rock Wool) in this thickness range and can achieve mass production (wholesale sandwich panels) with high cost-effectiveness.
- 100mm Thick Panels
- Application Scenarios: Used for building exteriors with higher insulation or acoustic requirements, industrial buildings in severe cold regions, or as enclosures for firewalls and equipment rooms.
- ZHUOZHU Solution: 100mm rock wool sandwich panels are an ideal choice combining high strength with Class A fire resistance. For large-span roofs, this thickness also provides better stiffness and wind uplift resistance.
Technical Consideration: When selecting thickness, it must be calculated together with purlin spacing (span) to ensure the structural safety of the panel. ZHUOZHU offers free technical calculation support.
Insulated Decorative Panel (Metal Carved Panel) Thickness Specifications and Application Analysis
Insulated Decorative Panels (Metal Carved Panels) integrate insulation function with exterior wall decoration. Their thickness typically refers to the total composite thickness of the insulation core and decorative facing.
Standard Thickness Specifications: 16mm, 20mm, 25mm
- 16mm Decorative Panel
- Characteristics & Applications: A lightweight decorative panel with a thin insulation core. Mainly suitable for façade renovation of existing buildings in temperate climates, providing basic insulation while enhancing aesthetics.
- ZHUOZHU Design: Typically uses thinner EPS or PIR core material paired with beautifully embossed Alu-Zinc steel sheets for quick installation.
- 20mm & 25mm Decorative Panel
- Characteristics & Applications: Standard and enhanced insulated decorative panels. 25mm thickness provides better insulation (R-value approx. 0.7-1.0 m²·K/W), suitable for integrated exterior wall insulation and decoration systems in new buildings, or retrofit projects with energy-saving requirements.
- ZHUOZHU Core Recommendation: We recommend using PIR as the core material to achieve superior insulation performance at the same thickness while ensuring the flatness and durability of the decorative facing.
System Value: Choosing metal carved panels is not just selecting a panel, but adopting a complete exterior wall cladding system. ZHUOZHU provides a complete solution including supporting connectors and seals, effectively preventing thermal bridges and ensuring long-term weather resistance.
Conclusion: ZHUOZHU’s Philosophy on Thickness Customization
