Description
Product Details
Optimize your roofing solution with premium PUF sandwich roof panels made of 0.4mm thick Pre-Painted Galvanized Iron (PPGI) sheets from AMNS on both sides. These panels feature a 40 kg/m³ density Polyurethane Foam (PUF) core manufactured using Recaz or equivalent high-quality chemicals, providing superior thermal insulation, structural strength, and weather resistance. Ideal for industrial, commercial, and residential roofing applications requiring energy efficiency, durability, and easy installation.
Key Features
- High-quality 0.4mm PPGI metal sheets sourced from AMNS on both faces for excellent corrosion resistance and enhanced structural integrity.
- Core insulation with dense (40 ± 2 kg/m³) rigid PUF foam, thermally efficient with a low thermal conductivity of around 0.024-0.03 W/m·K.
- Panels designed with tongue-and-groove joints for airtight sealing and minimal thermal bridging, ensuring consistent insulation performance.
- UV-resistant and weatherproof coating providing long-lasting protection against harsh environmental elements.
- Panel sizes customizable in width (approx. 1000-1200mm effective width) and length up to 12 meters for versatile roofing needs.
- Fire retardant and self-extinguishing polyurethane foam core enhancing safety standards.
