Sandwich elements such as type P panels offer outstanding insulation due to the use of PIR rigid foam as insulating core. High-precision manufacturing and an exact fit during assembly ensure that your cold-store or deep-freeze units are completely diffusion-resistant. This is partly due to the fact that we do not mill the tongue-and-groove foam profiles of the elements before cooling is finished. In addition, the joint geometry of the double tongue-and-groove joints with a labyrinth effect in four ideal positions allows highly durable seals to be used. Quick and easy assembly means that your individual cold-store or deep-freeze units are assembled in the shortest time
