They are prefabricated panels made of steel sheets and expanded polystyrene (Styrofoam) or polyurethane (obtained by the reaction of isocyanate with polyhydroxyl in the presence of catalysts), thus making a sandwich of insulating material. Thus the product is highly resistant and effective in insulation.
There are several advantages to using isopainers in the construction of cold rooms such as:
Quick and easy assembly, more efficient vapor barrier, ease of maintenance and more.
