Zulte, Belgium

The Zulte manufacturing plant in Belgium has some of the most advanced high speed metallic sputtering capabilities in the word. The basic sputtering process involves a large vacuum chamber and an inert or reactive gas atmosphere. Electrical energy imparts a negative charge to the atoms or molecules of gas. A low vacuum pressure allows the negatively charged particles to move freely around the chamber at high velocity. When those charged particles strike a cathode which contains the metal that is going to be applied to the film, atoms of the metal or metallic oxide are dislodged from the cathode at high velocity. These particles strike the film substrate creating a thin later of metal on the film. Sputtered films primarily feature either metal or a metal alloy, such as stainless steel, gold, or even platinum. Some sputtered films feature a metal oxide.

Sputtering creates a film that has excellent solar heat control properties like those produced by the metallizing process. Sputtering is a versatile process as several layers of different metals can be applied to the same piece of film resulting in spectrally selective films such as Panorama Hilite 70 or Solar Gard LX 70.

The Zulte plant also features slitting lines for cutting film into the finished sizes for customers.
