Flat insulated roof panels combine insulation, protection, and finished surface into a single factory-prefabricated component for low slope roof applications with 2-4 degree pitch. These panels streamline installation compared to traditional multi-layer roofing systems while delivering thermal performance and weather resistance for commercial, industrial, and residential buildings.
The panels feature a closed-cell Polyisocyanurate (PIR) foam core providing R-values from 7.0 to 8.0 per inch, sandwiched between steel sheets for structural stability. Advanced options include proprietary technologies like QuadCore for enhanced thermal resistance and fire performance. Panel thicknesses range from 1 to 8 inches with R-values reaching R-64 or higher.
Available configurations include trapezoidal profiles and standing seam designs with exposed or hidden fastener systems. Panel widths typically range from 24 to 42 inches for commercial applications, with custom lengths up to 54 feet. Various colors and specialized coatings like Colorcoat HPS200 Ultra are available for both exterior and interior faces.
Installation requires non-combustible substrates with minimum 2-degree pitch for drainage. Panels attach to wooden or steel trusses using specialized screws or clips designed for insulated panels. The lightweight, prefabricated design enables fast installation with fewer trades compared to conventional built-up systems.

Frequently Asked Questions
What is a flat insulated roof panel?
A flat insulated roof panel is a component that delivers a walkable surface with a clean washable interior, providing thermal and overall weather resistance in a single pass. It is designed for low slope roofing systems, typically with a pitch between 2 and 4 degrees to ensure good drainage.
What are the advantages of using RaxPanel flat insulated roof panels?
RaxPanel flat insulated roof panels offer a walkable surface, thermal and weather resistance, and allow you to get the most out of the space in a building without sloping surfaces. They provide a complete roof in only two components, simplifying design and installation by eliminating traditional layers like steel deck, vapor barrier, and multiple insulation boards, making it a high-performance, sustainable, and economical alternative.
Can I install RaxPanel flat insulated roof panels on my own?
While installation can be complex, the system is designed to simplify procurement and installation. However, for safety and correctness, it is often recommended to consult with professionals, especially for components like water management and membrane application.
What is the recommended pitch for a flat roof using RaxPanel panels?
For a flat roof, the recommended pitch is between 2 and 4 degrees. A minimum pitch of 2 degrees ensures good drainage while maximizing usable space.
How does the RaxPanel system reduce installation time and cost?
The RaxPanel system reduces installation time and cost by providing a complete roof in only two components, eliminating the need for traditional, individual elements such as a steel deck, vapor barrier, multiple layers of board insulation, and cover boards. This streamlined approach simplifies design, procurement, and installation.
Is the surface of RaxPanel flat insulated roof panels walkable?
Yes, RaxPanel flat insulated roof panels deliver a walkable surface with a clean washable interior, making them suitable for maintenance and access.
