Puf Roofing Sheets
Waterproof: The PU sandwich panel has a tight structure, ensuring excellent waterproof performance.
Sound insulation: The porous structure of the EPS core (if applicable) effectively absorbs sound waves.
Energy saving: Its thermal insulation performance helps reduce building energy consumption to achieve energy-saving goals.
Economical and practical: With low costs and high cost-effectiveness, it is suitable for large-scale applications in industrial plants, warehouses, cold storage, temporary buildings, etc.
Product Introduction
Puf Roofing Sheets are high-performance building materials with excellent insulation & structural strength. Their 3-layer design (rigid PU foam core between metal facings) offers energy-efficient construction, cutting heating/cooling costs via superior thermal insulation. Lightweight for easy installation & reduced load, they feature fire resistance, soundproofing, durability, weather-resistance & low maintenance, suiting industrial/commercial/residential roofing. Versatile for various architectures, balancing function & aesthetics.

Project Cases
Sandwich panels serve as versatile solutions across industries, transforming construction in industrial facilities, factories, and transportation. Their unique properties are vital for cold chain logistics, healthcare, and specialized applications. Landmark projects like Jidong Intelligent Manufacturing New City (smart industrial ecosystems) and Qingzhou High-Speed Railway Station (transport efficiency) highlight their performance. They ensure optimal conditions in Gold and Silver Valley Industrial Park, International Fresh Cold Chain Park, Hailier Pharmaceutical facilities, and Boxing People's Hospital, leveraging durability, energy efficiency, and hygienic features for operational success and environmental control.
Flow Chart of Polyurethane
The production process begins with material prep (unwinding, film application), then pressing for shape. Next, spraying, preheating, and foaming form the PU structure. After precise guiding & cutting to size, cooling ensures structural stability. Final steps: unloading, packaging for distribution, completing the efficient production cycle.
Our Factory
The factory's production lines are intricately coordinated, with minimal distances between workshops for parts and components, enabling rapid material flow. This setup reduces production logistics costs and eliminates extra expenses from repeated loading/unloading.
