Insulated Roof Panels | High R-Value for Buildings

Insulated Roof Panel

Insulated roof panels combine metal substrates with core insulation materials to deliver complete roofing solutions. These prefabricated components feature protective outer layers bonded to thermal insulation cores, enhancing building performance through superior energy efficiency.

The panels achieve high R-values ranging from R26 to R52 depending on thickness (2-6 inches), indicating excellent resistance to heat flow. Closed cell polyurethane or polyisocyanurate insulation cores create airtight structures, reducing thermal bridging and condensation risks. Lightweight construction enables labor-saving installation using standard framing tools.

Material composition features two metal skins of galvanized steel or aluminum bonded to high-density foam cores. Insulation options include Expanded Polystyrene (EPS), polyurethane, or polyisocyanurate foam, with some variants incorporating foil radiant barriers. The tongue-and-groove interlocking system ensures secure assembly, with standard widths of 26 inches or 4 feet and custom lengths up to 20 feet.

Applications span residential and commercial projects including patios, carports, industrial facilities, and cold storage rooms. Panels meet International Residential Code (IRC) Section 6 standards and Class 1 Fire Rated requirements. Design options include standing seam or high-rib profiles with various finishes and textured surfaces for customized aesthetic and structural requirements.

Carport Sandwich Panel

A structural, all-in-one roof panel combining steel skins with a high-density foam core for long-spanning capabilities. It is defined by its high-gloss, low-maintenance underside finish and a durable top surface engineered for excellent weather resistance and protection from the elements.

Conservatory Roof Panel

A specialized glazing panel featuring multi-wall polycarbonate or a composite structure with an insulated core. It is designed to provide high thermal insulation, preventing extreme heat buildup while offering excellent light transmission, glare reduction, and UV protection for a comfortable internal environment.

Flat Insulated Roof Panel

A high-performance composite panel designed for low-slope and flat roof constructions, featuring a high-density, structural insulation core. It is characterized by its high compressive strength for foot traffic and load-bearing capacity, and a robust, weatherproof top membrane for primary waterproofing.

Patio Insulated Panel

A structural roof panel engineered to create comfortable, insulated outdoor living spaces, featuring a decorative ceiling finish. It combines a durable, weather-resistant steel topside with a high-performance foam core that significantly reduces radiant heat transfer for a cooler patio environment.

Pergola Sandwich Panel

An insulated roofing panel designed to convert open pergolas into solid, weatherproof structures. It provides exceptional spanning capabilities and is defined by its ability to block solar heat gain, providing a cool, shaded area while maintaining a clean, finished ceiling appearance.

Roof Tile Sandwich Panel

A composite insulated panel featuring a top exterior steel skin that is profiled and stamped to replicate the aesthetic of traditional roof tiles. This design combines the classic look of a tile roof with the high thermal efficiency and structural performance of an insulated core.

Snap Lock Insulated Roof Panel

An insulated roof panel system featuring a patented snap-lock joint with concealed fasteners. This interlocking design provides a continuous, weathertight seal and superior structural performance, allowing for rapid, low-pitch installation while ensuring excellent thermal efficiency and a clean architectural finish.
