Engineered core systems complying with Euroclass A1 and European building safety directives
In Spain, the construction of industrial buildings, logistics hubs, and commercial offices is strictly regulated by the Código Técnico de la Edificación (CTE). Specifically, the Documento Básico de Seguridad en caso de Incendio (DB-SI) and Documento Básico de Ahorro de Energía (DB-HE) place rigorous conditions on modern build envelopes.
"With the expansion of logistics sectors in Madrid's Henares corridor and Barcelona's metropolitan ring, there is a substantial demand shift from standard combustible EPS/PU cores to structural mineral rock wool solutions."
Building designs must account for thermal comfort and structural protection across diverse climates, ranging from the arid warmth of Andalusia to the high-humidity maritime conditions of the northern Basque and Galician ports. Ningbo Jonas Build Co., Ltd. customizes panels with high zinc-coated steel interfaces (Z275, Galfan, or PVDF coatings) to resist local microclimatic oxidation.
Our rock wool core sandwich panels achieve A1 and A2-s1,d0 classifications, preventing vertical fire spread in high-occupancy commercial projects and industrial warehouses across Malaga, Valencia, and Bilbao.
With density levels spanning up to 150 kg/m³, our structural composite wall systems act as noise barriers, perfect for acoustic attenuation in machinery centers and airport structures.
Technological pathways, carbon neutrality, and the shifting dynamics of modular fast-track construction
Global standards favor materials with comprehensive Environmental Product Declarations (EPD). Jonas Build uses bio-soluble volcanic fibers that lower raw-material life cycle emissions.
To reduce onsite labor costs, developers rely on prefabricated, inter-locking panels. Our tongue-and-groove joint profile guarantees fast vertical erection and immediate structural weather-proofing.
Modern logistics parks mix cold-storage (PIR panels) and dry/high-risk zones (mineral wool). We offer hybrid PU-sealed-edge rock wool panels that optimize insulation while ensuring mechanical fire safety.
