Isolar Neutralux is a brand new insulting glazing of low emission. The low emission is a barrier, which reduces considerably the transmission of energy. This type of glass, of low emission, is the result of a high-technology production. Several metallic layers rich in silver are successively deposited in these glasses, and as a result we have a transparent, colourless glass, like the original float glass.
The thickness of these layers is a millionth millimetres. A glass, to which just one silver layer of this thickness were applied, would not be transparent. For a right application of the metallic layers, the glasses should have been washed and dried authomatically. Afterwards, they go though several vacuum chambers, where the different layers are applied, following the cathodic spraying method. This process is also called "Sputtern".
The magnetic field used to improve the quality of the layers applied has been called "Magnetron Process".
After this process, the glasses with metallic layers are piled up and prepared for their transport.
They must be packed and stored, so that silver, which is very sensitive, cannot react with the relative humidity.
