Polyisocyanurate (PIR)
A new macromolecular structure called polyisocyanurate is formed when the main components of the polyurethane foam chemically react at different mixture quantities. Polyisocyanurate rigid foam is the version of polyurethane with higher, enhanced fire resistance performance due to the difference in its structure. In case of a fire, the formation of smoke is very low when compared to polyurethane.

Prepainted Galvanized Steel Coating Layers
The sheet galvanized by being coated with a zinc layer between 100 gr/m2 - 275 gr/m2 by using the hot dipping method is produced on highly automated continuous lines called coil coating.After the coil is opened, the lower and upper surfaces are cleaned with special chemicals, and pretreated so as to increase its corrosion resistance and to strengthen paint adherence. Primer coat is applied on both surfaces. The backcoat increases the stickiness of the sandwich panel insulation core. After surfaces with primer coat are baked, topcoat is applied on the front surface. They are baked again, cooled, and packaged in prepainted coils to be used in sandwich panel production.
