Interior Renovation
Manufactured on high-speed continuous foaming and precision profiling lines, our portfolio combines thermal efficiency, moisture barrier protection, and high mechanical deflection resistance for French logistics hubs, agro-alimentaire complexes, and cleanrooms.
The modern French industrial and commercial building market is undergoing one of the most rigorous legislative transformations in Europe. Navigating thermal transmittance thresholds and carbon assessments demands strict manufacturing controls.
Specifying insulated wall panels (*panneaux sandwich isolants pour bardage*) across France requires comprehensive compliance with dual mandates: dynamic thermal regulation under RE2020 (formerly RT2012) and the stringent decarbonization pathways prescribed by the Décret Tertiaire. For general contractors (*entreprises générales de bâtiment*), engineering consultancies (*bureaux d'études thermiques*), and structural architects, material selection is no longer restricted to surface aesthetics; it is deeply bound to life-cycle carbon expenditure, declared thermal conductivity (λD), and documented reaction-to-fire performance.
Under French building codes, exterior wall cladding systems must align with EN 14509 (Self-supporting double skin metal faced insulating panels). Thermal boundaries must achieve strictly targeted overall transmittance values (U-values typically required between 0.15 W/m²·K and 0.22 W/m²·K depending on regional climatic zones from H1 to H3). Simultaneously, the fire behavior of building envelopes must comply with the Instruction Technique 249 (IT 249) regarding fire propagation across façades. This regulatory framework places stringent obligations on the selection of core formulations: Polyisocyanurate (PIR) cores must guarantee strict flame self-extinguishing behavior and low smoke development (Euroclass B-s1,d0), while high-occupancy public access buildings (ERP - Établissements Recevant du Public) and high-rise commercial structures require non-combustible mineral rockwool cores achieving Euroclass A2-s1,d0 or A1.
France’s RE2020 calculates life-cycle environmental impact over a 50-year building lifespan. Our panel systems provide validated Environmental Product Declarations (EPD / FDES) registered in the INIES database, aiding engineering firms in minimizing the overall ICconstruc indicator.
Tested in accordance with NF EN 13501-1, our insulated panels meet rigorous reaction and resistance-to-fire ratings. From self-extinguishing high-index PIR formulations to structural stone wool (Laine de Roche) exceeding 120 minutes of fire resistance (EI120).
Commercial building operators must cut final energy consumption by 40% by 2030, 50% by 2040, and 60% by 2050. Replacing obsolete single-skin or deteriorating built-up systems with our high-density insulated cassettes yields rapid thermal payback.
From the agricultural and food processing strongholds of Brittany to the heavy logistics corridors of Île-de-France and Auvergne-Rhône-Alpes, distinct building functions demand purpose-built sandwich panel systems.
Concentrated heavily in Brittany, Normandy, and the Loire Valley, France's food processing plants operate under stringent hygiene protocols governed by DDPP directives. Our food-grade cleanroom and cold storage insulated panels utilize chemically inert food-safe coatings (such as 120μm Food-Safe PVC/Plastisol and PVDF) resistant to continuous enzymatic washing, aggressive chlorinated sanitizers, and high-pressure steam cleaning.
Designed with tight double tongue-and-groove joints incorporating factory-injected continuous silicone seals, these panels eliminate internal condensation and biological mold colonization, maintaining isothermal environments down to -30°C in deep-freeze logistics hubs.
Spanning the strategic corridor from Lille through the Paris region, Lyon, and down to Marseille, class-A mega distribution platforms demand rapid erection times, structural wind-span performance under Eurocode 1 (NF EN 1991-1-4), and internal fire compartmentation. Our continuous-line PIR insulated wall panels allow spans up to 6 meters between intermediate steel girts, dramatically reducing the structural weight and cost of the primary steel frame (*charpente métallique*).
The micro-ribbed or architectural flat external profiles deliver crisp, contemporary elevations suited for international asset managers and institutional real estate developers.
In prestige viticulture regions—including Bordeaux, Champagne, Burgundy, and the Rhône Valley—maintaining ultra-stable interior temperatures and controlled relative humidity throughout seasonal extremes is critical for vat fermentation and barrel maturation. Our composite sandwich panels provide thermal inertia with zero air infiltration (Class A4 under NF EN 12114).
Paired with acoustic mineral wool cores, these building envelopes dampen external ambient vibrational energy, protecting vintage cellars while harmonizing aesthetically through custom pre-laquered organic architectural finishes in matte slate, anthracite, and earth tones.
Driven by France's national carbon reduction strategies and municipal energy renovation grants (CEE - Certificats d'Économies d'Énergie), millions of square meters of aging industrial facilities built in the 1970s through 1990s require structural envelope retrofits. Our lightweight insulated panels can be installed directly over existing steel subframes with minimal structural reinforcement.
This allows active factories and warehouse facilities to remain fully operational during façade modernization while immediately reducing winter heat losses and summer cooling energy expenditure by over 45%.

Direct-from-manufacturer sourcing eliminates intermediate trading margins and guarantees strict batch traceability from prime steel coils to container loading.
Our plant operates continuous high-speed double-belt laminator lines equipped with automated multi-component high-pressure dosing units. The core adhesive polymerization occurs under uniform heat and pressure, eliminating core delamination, micro-voids, and thermal blisters. Precision roll-forming stations shape internal and external steel facings from 0.40mm to 0.75mm thickness in galvanized, Galfan, or Aluzinc steel substrates.
To withstand ocean freight and overland transport to French project sites, every panel pack is automatedly wrapped in UV-resistant protective film, reinforced with high-density expanded polystyrene base bearers, and bound with edge corner protectors. Panels are packaged in container-ready stack sequences tailored directly to your site assembly order, allowing direct unloading via site crane or telescopic forklift.
Answers to technical, regulatory, and logistical inquiries regarding procurement, compliance, and on-site panel erection in France.
Yes. All panels produced for European export carry authentic CE marking under standard NF EN 14509 for factory-made self-supporting double skin metal faced insulating panels. We supply full Declarations of Performance (DoP), factory production control documentation, and independent laboratory test certificates with each consignment.
Our high-index PIR formulations are chemically engineered to achieve Euroclass B-s1,d0 in accordance with EN 13501-1. When installed alongside compliant steel structural girts and firestop rockwool horizontal barrier bands (*bandes coupe-feu*), our envelope systems satisfy the French IT 249 guidelines for limiting external and cavity flame propagation.
For buildings situated within coastal zones (marine atmosphere C4 or C5 under NF EN ISO 12944), we recommend HDG steel substrates with a minimum Z275 zinc mass, coated with either 50μm High-Durability Polyurethane (PUR/Puda), 35μm PVDF (Polyvinylidene Fluoride), or 120μm/200μm Plastisol, delivering superior resistance against salt-spray corrosion and chalking.
Yes. We cut panels continuously to precise millimetric shop-drawing schedules, with lengths ranging from 2.00 meters up to 16.00 meters (subject to road transport regulations on French departmental and national routes). Custom lengths significantly lower installation labor and eliminate on-site slicing waste.
Standard fabrication lead times run between 2 to 3 weeks following approved production cutting lists. Ocean shipments arrive through major hubs including Le Havre, Dunkirk, and Fos-sur-Mer / Marseille. We handle comprehensive shipping documentation, bill of lading releases, and custom Incoterms (CIF, CFR, or DDP directly to jobsite).
Our insulated wall panel longitudinal edges feature a double interlocking tongue-and-groove joint profile with a factory-applied low-conductivity elastomeric thermal gasket. The metal skin incorporates a structural thermal break cut at the tongue interface, reducing Ψ (psi) linear thermal transmission values to < 0.015 W/(m·K).
Yes. Every order is supported by certified permissible uniform load tables (ΔP in daN/m²) calculated for single, double, and multi-span conditions in accordance with EN 14509 Annex E. These verify structural resistance against regional wind suction and pressure forces under French Eurocode 1 national annexes.
For standard colors (RAL 9002, 9006, 9010, 7016) and standard thicknesses (40mm to 150mm), our minimum production batch is 500 m². For non-standard RAL architectural shades or custom sheet gauges, the MOQ is 1,200 m² (equivalent to one raw coil run).
