They are special paints that can modify the absorption of heat on the coating (roof, facade) due to solar energy and consequently regulate internal temperatures, making the rooms cooler in hot periods and milder in cold periods. This is possible because the heat wave is reflected by the metal and the heat is rejected in summer and is retained in winter. The energy benefit is between 2 and 5 ° C.
The advantages of this finish are:
- energy saving (less use of air conditioning)
- reduction of the thermal tension of the metal with consequent increase in the duration of the structure.
