APVC roofing tile is an advanced, multi-layered plastic roofing material made from modified PVC (Polyvinyl Chloride) via co-extrusion technology. It is primarily designed for superior corrosion resistance, durability, and thermal insulation, making it a popular choice for industrial and commercial buildings.
Core Structure & Material
APVC tiles typically feature a double or triple-layer composite structure:
Surface Layer: Modified weather-resistant resin (often blended with ASA or acrylic) for UV protection, anti-aging, and color stability.
Core Layer: High-strength rigid PVC to provide structural rigidity, impact resistance, and load-bearing capacity.
Base Layer: Tough, anti-corrosive PVC material for added durability and insulation.
Key Advantages
Exceptional Corrosion Resistance: Highly resistant to acids, alkalis, salt spray, and chemical fumes. Ideal for coastal areas, chemical plants, and factories.
Excellent Heat Insulation: Effectively blocks heat transfer, keeping interiors cooler and reducing energy costs.
Superb Weatherability: Withstands extreme temperatures, heavy rain, and strong winds without cracking or deforming.
Lightweight & Easy Installation: Lighter than concrete or metal tiles, reducing structural load and simplifying installation.
Fire Retardant: Generally achieves a B1 fire-resistance rating.
Sound Insulation: Reduces noise from rain and wind by 30-50% compared to metal roofing.
Long Lifespan: Lasts 20-30 years or more with minimal maintenance.
Eco-friendly: 100% recyclable at the end of its life cycle.
Specifications
Thickness: Commonly 1.5mm to 3.0mm.
Width: Standard width is around 1130mm.
Length: Customizable (typically cut to 6m or less for transport).
Colors: Available in various colors (white, blue, green, red, gray).
Profiles: Corrugated (wave) or trapezoidal.
Common Applications
Industrial: Factories, warehouses, chemical plants.
Commercial: Markets, shopping malls, stadiums.
Agricultural: Greenhouses, livestock sheds.
Residential: Villas, carports, and high-end houses.
