Cold room panels are specialized building materials designed for constructing insulated environments such as refrigerated warehouses and food processing facilities. Their key features include excellent thermal insulation properties, durable construction, easy installation, and airtight sealing. These panels help maintain stable and controlled temperatures, ensuring the freshness and quality of stored goods while also promoting energy efficiency.
Due to its exceptional qualities, including environmental protection and light weight, polyurethane is the best thermal insulation material in the world and is being employed in a growing number of areas, including the cold chain industry.
Another name for polyurethane composite panels is “PU sandwich panels.”
The polyurethane core composite panel consists of two layers of colored steel plate on top and bottom, as well as an intermediate foamed polyurethane layer. It uses the most sophisticated six-component online automatic operation mixing and pouring technology available today to complete the online proportioning and mixing process of a factory or social batching center in a single session. It can also be adjusted at any time based on the temperature online, creating a distinctive building panel that is strong, energy-efficient, green, and environmentally friendly.

Although they rarely have the same personality, close relatives do share a family history. PUR and PIR insulation are comparable in that they have similar chemical compositions, yet they perform differently. Even though they differ in composition, they are comparable in that they are both lightweight and have low thermal conductivity, which helps buildings become more energy efficient by lowering the amount of energy needed for heating and cooling.
In essence, PUR foams are created through the reaction of a “polyol” and a “iso” component, where the polyol component’s OH groups create urethane linkages by chemically balancing the iso component’s NCO groups. Isocyanurates are created in PIR foams when the iso components interact with one another in trimerization processes.Additionally, excess iso forms urethane links when it combines with polyol.
In order to build an energy-efficient barrier, PUR insulation can be injected into wall cavities. Small areas can be filled with foam to produce an airtight seal. PUR has “the best thermal performance of all practical full cavity insulants,” according to the.Any kind of surface can be constantly sprayed with PUR foam. It is perfect for remodeling because it is typically less expensive than other materials.
Because PUR is a moisture-free material, its high water resistance helps reduce the effects of water damage in wall cavities in locations that are prone to flooding.
PIR insulation outperforms PUR insulation despite PUR’s advantages. Polyisocyanurate, or PIR, is commonly sawed into boards and used as insulated plasterboard, wall cavities, and insulated metal panels. PIR requires only half the thickness of conventional mineral-based insulation products due to its exceptional thermal performance.
PIR is well-known for use as a low-moisture barrier, much as PUR. PIR stands apart primarily due to its resilience to smoke and flames. In comparison to PUR products, PIR slows the spread of flames and lowers the amount of smoke released by the fire.
