Element high-performance PIR panels are specifically designed for insulation in cold storage facilities and industrial buildings, offering superior fire ratings and energy-saving capabilities; relevant test reports are included here.
Global demand for polyurethane (PU) insulation sandwich panels is steadily rising within the industrial sector. Thanks to their exceptional thermal insulation properties, these panels are widely used in cold storage construction projects.
This article provides a detailed analysis of the key differences between PIR-core and PUR-core panels.
What is PIR
PIR stands for Polyisocyanurate Foam. It is produced when isocyanate reacts with polyols under catalyst effects to form closed‑cell foam material. Compared with conventional polyurethane foam, PIR features superior physical properties and fire‑resistance, making it an ideal organic low‑temperature thermal insulation material.
Benefits include low thermal conductivity, lightweight structure, shock resistance and great application adaptability. It is widely used for thermal insulation in refineries, chemical plants, fertilizer factories, cold‑storage facilities and general industrial construction.
What is PUR
PUR stands for polyurethane. It is a polymer formed through the chemical reaction of isocyanates and polyols, featuring repeating urethane linkages in its molecular structure. Polyurethane materials offer diverse properties and a wide range of applications across numerous product categories; among these, PUR foam accounts for the largest market share.
Currently, B1-grade PUR produced in China approaches the performance specifications of PIR while being significantly lower in price.
Element PIR Insulated Sandwich Panels
The Element series sandwich panels utilize a next-generation pentane-blown PIR core, achieving a Class B1 fire rating. The high-density rigid foam core effectively blocks heat transfer, combining superior thermal insulation with outstanding fire safety performance.
These panels effectively minimize air convection and solar heat radiation, thereby reducing energy consumption, operating costs, and CO2 emissions while curbing heat loss in buildings.
Compliant with major global fire safety standards, they are suitable for a wide range of international projects.
Low VOC (Volatile Organic Compound) emissions support environmental protection and sustainable building practices.
Element sandwich panels offer excellent thermal stability and a high fire rating. A 5-year product quality warranty is provided; the reference price for 100mm cold storage panels is 15 USD/m².
