Product Specification
Element PU insulation roof panels are purpose-built for rooftop photovoltaic projects. Panel thickness can be customized from 50mm to 100mm. The standard effective width is 1000mm, and lengths are cut to project specifications for seamless installation.
Each panel features a 0.5mm high-strength color steel top sheet. We support all standard RAL colour options to satisfy different architectural design requirements. Filled with high-density polyurethane foam core, these roof panels provide excellent thermal insulation, waterproofing and load-bearing capacity. Lightweight yet robust, they streamline on-site construction and enable integrated roof & photovoltaic systems for industrial factories and commercial buildings.
