Unique Materials for Cold Room Sandwich Panel

Luton uses environmentally friendly and thermal insulation materials to produce sandwich panels for cold rooms. These materials include the following:

  • PVC Foam Plastic: The advantages of PVC foam plastic material are low water absorption, low thermal conductivity, high durability, and high compression.
  • EPS (Polystyrene Foam): Resin is the primary base material of polystyrene. They are lightweight, alkali and acid resistant, and low-temperature resistant. In a cold room, most of the polystyrene foam is quick to absorb water.
  • XPS (Extruded Polystyrene Foam: It has good thermal insulation, low thermal conductivity, excellent moisture resistance, and heat insulation.

Cold Storage panel advantages

Insulation Effect – Compared with different core materials

  1. The core material adopts a new generation of the rigid PU PIR foam composite material system, which effectively blocks heat conduction, thereby excellent thermal insulation performance

  2. Rational joint design, great thermal insulation effect, and superior mechanical performance

  3. Excellent thermal insulation performance, high economic benefits, reduced air loss, and solar radiant heating, thereby lowering energy consumption & costs, CO2 emissions, and building energy consumption

  4. Meet various major fire protection standards in the world

  5. Lower volatile organic compound (VOC) emissions, environmentally friendly and sustainable



In terms of raw material proportioning and process output, PUR products employ the globally advanced six-component online automatic (SIMENS) mixing and pouring technology and have realized six-component continuous foaming for the first time in China. With the technology, the mixing and proportioning process may be finished in an online way; the formula may be adjusted according to environmental changes; air feeding and mixing devices may be used to make raw material mixing more even and foam finer, thus producing high-strength, energy-saving, and environmentally friendly building boards.


Polyisocyanurate is called PIR for short. For the composite boards developed , excessive isocyanurate is added and ring structure and higher isocyanurate index are employed in the compounds to form compact PIR products, thus ensuring greater stability and excellent heat and fire resistance for the internal rigid foams. Experiments show that the products can endure a temperature up to 200ºC in short time period or to 160ºC for long time.
