❄️ OSB Sandwich Panel: PU vs Rock Wool for Low-Temperature Warehouse Enclosure
When designing enclosure structures for low-temperature warehouses, numerous engineering purchasers hesitate to select proper OSB sandwich panels: PU OSB sandwich panel or rock wool OSB sandwich panel. Both OSB sandwich panels take OSB boards as facing sheets, while different core materials create huge gaps in comprehensive performance.
🧊 PU OSB sandwich panel adopts rigid polyurethane foam core. It features excellent thermal insulation with low thermal conductivity, effectively cutting cold leakage inside low-temperature warehouses and saving long-term refrigeration power costs. This OSB sandwich panel is lightweight, easy to transport and quick to install. Its fire performance is average, making it ideal for conventional low-temperature warehouses prioritizing energy efficiency without stringent fire protection standards.
🔥 Rock wool OSB sandwich panel uses rock wool as core material. It achieves superior fire resistance and stable high-temperature performance to satisfy strict industrial fire codes. However, its thermal insulation effect is inferior to PU OSB sandwich panel, leading to higher energy consumption of refrigeration systems. This rock wool OSB panel is recommended for warehouses storing combustible materials with mandatory fire acceptance requirements.
