Engineered for compliance with France’s strict environmental laws, our initial product selection presents premium sandwich and composite panel systems designed for quick assembly and structural stability.
The commercial and industrial real estate landscape in the Île-de-France region, especially surrounding the Paris metropolitan area, is undergoing its most significant regulatory transition in a generation. With the enforcement of the RE2020 (Réglementation Environnementale 2020), French construction project developers, general contractors, and architects must strictly manage both the operational energy footprint and the embodied carbon of building materials.
Industrial storage warehouses, cold-chain logistics hubs (such as those feeding the Rungis International Market), and high-tech manufacturing plants in Seine-et-Marne or Val-d'Oise are no longer permitted to rely on outdated building materials. Modern building envelopes must demonstrate low lifecycle carbon impact, outstanding thermal resistance, and strict compliance with European fire class safety codes (specifically Euroclass A1, A2, and B classifications).
Calculated lifecycle carbon impact metrics. Our structural insulated panels are produced with low-carbon steel coatings and eco-friendly blowing agents to minimize global warming potential (GWP).
U-values down to 0.11 W/m²·K. Rigid polyurethane (PUR) and polyisocyanurate (PIR) cores ensure minimal thermal bridging, reducing HVAC cooling and heating costs in northern France.
Rigorous fire safety standards. From Class A1 Rock Wool core panels for fire containment walls, to self-extinguishing B-s1, d0 classified PIR panels for standard logistics facilities.
Selecting the appropriate core material and sheet thickness is essential for meeting wind load calculations (Eurocode 1) for the Paris Basin and surrounding logistics networks. Below is a structural design matrix showing standard performance indexes:
| Insulation Core Type | Standard Thicknesses (mm) | Thermal Conductivity (λ - W/m·K) | Euroclass Fire Rating | Typical Applications in Paris Markets |
|---|---|---|---|---|
| Polyisocyanurate (PIR) | 50, 80, 100, 150, 200 | 0.020 - 0.022 | B-s1, d0 (Self-Extinguishing) | Cold Storage Facilities, E-commerce Logistics Hubs, Retail Warehouses |
| Rock Wool (Mineral Fiber) | 50, 75, 100, 150 | 0.038 - 0.044 | A1 / A2-s1, d0 (Non-Combustible) | Data Centers, Battery Factories, Fire-Rated Partition Walls |
| Expanded Polystyrene (EPS) | 50, 75, 100, 150, 200 | 0.035 - 0.039 | Class E / D-s2, d0 | Cost-Effective Commercial Sheds, Prefabricated Offices, Temporary Structures |
| MGO Cleanroom Composites | 50, 75 | Varies based on core | A2 Non-Combustible | GMP Biotech Labs, Pharmaceutical Assembly Plants near Paris Saclay |
From customized prepainted galvanized steel structures to high-performance thermal insulation sandwich cores, these systems provide complete building envelope options for complex construction programs.
Procuring metal sandwich panels from our advanced automated factories in China to Paris project sites is designed to run smoothly and efficiently. We coordinate the complete logistics chain, shipping via major ocean routes to the Port of Le Havre or the Port of Dunkirk, followed by inland waterway barges or direct flatbed truck delivery along the Seine river corridor right to your construction site.
Each container is loaded using specialized packing systems that protect the panel tongues, grooves, and pre-applied joint seals. By coordinating structural steelwork fabrication with the panel manufacturing schedule, we help minimize site storage requirements in high-density urban areas of Paris.

Under current French urban planning regulations, new commercial buildings must allocate a portion of their roof space to either solar photovoltaic installations or green vegetation. Our engineering team designs roofing panels with the structural load capacity and specialized profile crowns required to support integrated mounting rails.
By selecting our high-strength steel outer skins (0.6mm or 0.7mm Grade S320GD) combined with dense polyisocyanurate (PIR) cores, developers can install photovoltaic panel arrays without compromising the underlying building envelope.
Explore our wider range of insulated panels, roll forming equipment, and modular building components. These products are fully customizable to meet the specific load and design requirements of your project.
