Sandwich panel is a light and combined structure consisting of two layers of external coating and middle insulating (foam). The coating is usually made of galvanized, zincalume (aluzinc), and aluminum, or aluminum foil, nylon, craft paper. The insulator core is made of polyurethane, polystyrene, rockwool, and asbestos.

Parsin sandwich panels features

Sandwich panel insulator core of the Parsin Company is made of hard polyurethane foam with a density of 40±2 kg/m3 with the fire resistance class of B2 (slow burner) and the resistance class of B1 (fireproof ).

According to the application of sandwich panels, various compounds  are  use to coat the sandwich   panel  core.

  • - Both sides metal sheet
  • One side metal sheet and one side nylon
  • One side metal sheet and one side aluminum foil
  • One side metal sheet and one side craft paper
  • Both sides nylon
  • Both sides craft paper
  • Both sides aluminum foil

The polyurethane sandwich panel with galvanized  metal  sheets, colored metal sheets, and aluminum sheets are usually used for external covers against moisture and corrosion. While, the polyurethane sandwich panel covered with aluminum foil, nylon, polyethylene,  and paper are used  for  internal  applications such as insulation of cold storages  floors (under concrete  layer),  aquatic  constructs  floors, etc.

Application of sandwich panels

  • Isolated rooms
  • Mobile hospitals and clean rooms
  • Various industrial and office partitions
  • Food transport containers
  • Types of Connex and pre-made house
  • Agriculture saloons, greenhouses, and mushroom farming saloons
  • Sport complexes and indoor pools
  • Types of mobile Connex for special cases
  • Military shelters and mobile laboratories

Advantages of sandwich panels

  • Light weight (resulting to save and use less material in buildings and reduced total costs)
  • Low heat transfer coefficient
  • Fire resistance class of B1 and B2 Low
  • installation cost
  • Moisture insulator
  • Sound insulator
  • Appropriate mechanical features (against shear, tensile, and pressure forces)
  • Low energy consumption (cooling and heating cost-effectiveness)
  • High resistance against microbial and biologic contamination
  • Product beauty and various colors
