Product Introduction
Polyurethane roof panels are high-performance building envelope materials engineered for superior thermal insulation, waterproofing, and structural efficiency. Composed of premium color-coated steel plates as the surface layer and rigid polyurethane foam with a closed-cell rate of over 95% as the core, these panels are manufactured via a continuous automated production line. Boasting an ultra-low thermal conductivity of as low as 0.022 W/(m·K), the panels outperform traditional insulation materials by 3 to 5 times, enabling significant reduction in building energy consumption. Their lightweight yet high-strength design supports large-span installation, making them a go-to integrated energy-saving solution for industrial plants, logistics warehouses, commercial buildings, and modern agricultural facilities.
Product Advantage
The panel’s core material adopts an advanced formula, with thermal conductivity ranging from 0.022 to 0.024 W/(m·K). Field tests show that buildings using these panels experience a roof surface temperature reduction of over 20℃ in summer and a 60%+ cut in heat loss in winter, achieving a comprehensive building energy-saving rate of 40% to 50%.

Produced via precise composite molding on imported German continuous production lines, the panels deliver a compressive strength of over 150kPa, allowing direct pedestrian access for maintenance. With a density of only 40-45kg/m³, they are over 90% lighter than traditional concrete roofs, significantly reducing building structural load and foundation costs.

Equipped with an exclusive patented 360° lock seam lap joint system and special waterproof sealing tape, the panels form a fully sealed waterproof layer. The surface layer uses 55% aluminum-zinc alloy coated steel plates, offering a corrosion resistance lifespan of over 25 years. Third-party tests confirm no leakage risk under heavy rain and strong wind conditions, backed by a 15-year warranty.

The core material meets national fire safety standards with a B1-level flame-retardant rating, and A-level fireproof composite cores are available as an option. The production process adopts an environmentally friendly fluorine-free foaming technology (cyclopentane system), and the product has obtained China Green Building Materials Product Certification, making it suitable for food, medicine, and other eco-sensitive industries. Key keywords: B1 grade fireproof roof panel, fluorine-free foamed polyurethane board, green building material certified roof panel.

Product Uses
These panels are ideal for large industrial plants and logistics warehouses, as their lightweight high-strength properties enable large-span structures, minimize internal columns, and maximize storage and operational space. Superior insulation maintains stable workshop temperatures, ensuring efficient equipment operation and reducing air conditioning energy consumption.
As a key enclosure material for cold storage facilities, the panels’ ultra-low thermal conductivity and excellent moisture resistance maintain a stable temperature range of -25℃ to 15℃, prevent cold loss and condensation, and ensure the quality and safety of refrigerated goods.
Widely used in sports venues, exhibition centers, shopping malls, and supermarkets, the panels’ rapid installation shortens construction periods. Integrated design and diverse color options align with architectural aesthetics, while long-term waterproof and insulation functions enhance building comfort and operational economy.
Suitable for agricultural greenhouses and ecological breeding farms, the panels’ excellent insulation creates stable growth environments for plants and animals. Their corrosion-resistant and easy-to-clean surfaces meet agricultural hygiene requirements, supporting energy-saving and standardized modern agricultural production.
FAQ
