Improving energy efficiency in industrial buildings starts from the envelope – how effectively a structure can control heat transfer between the interior and exterior environments. One of the most reliable solutions is to combine pre-engineered steel structures with insulated panels from qualified suppliers. Understanding the concept Insulated sandwich panels are composed of two steel sheets bonded to an insulating core, typically polyurethane (PU), polyisocyanurate (PIR), or rock wool. This layered configuration minimizes heat flow through roofs and walls, allowing buildings to maintain a stable internal temperature with less
