It can be transparent so as to allow vision inside the furniture, and can be printed, tinted, enameled, frosted (in the case of glass), or coated with layers, so as for example to be low emissive (or reflect infrared radiation) to protect items inside the furniture from light and heat exté ⁇ eures. It can also be provided with layers and / or wires and / or metallic heating foils to prevent, for example, the formation of fogging, etc.
