This is an ordinary float glass with a metallic coating to reduce solar heat. This special metallic coating also produces a mirror effect, preventing the subject from seeing through the glass. It is mainly used in facades.
ProductionPyrolitic (On-Line): in this process, semi-conducted metal oxides are directly applied to the glass during the float glass production while the glass is still hot in the annealing lehr. These are hard coatings which are relatively harmful to the environment.
Vacuum (magnetron) Process (off-line):in this process one or more coats of metal oxide are applied under a vacuum to finished glass. The coatings applied by this technique are soft and must be protected against external influences and are therefore used for the interior side of glass panes. There are some other techniques for the off-line coating:
- Immersion Process
- Chemical Process
- Foil
- Screened Glazing
Reflective glass is a product resulted from multi-metal coatings on the float glass as raw material. Through the application of vacuum coating, the finished product characterizes various visual effects and different optical and calorific features.
Reflective glass absorbs and reflects a major proportion of the sun's direct energy more effectively than tinted glass.
A coating is applied during glass manufacture. It is ready to be cut, heat strengthened and toughened. This product is sometimes called a 'hard coat' reflective.
Features:
Minimized solar heat gain and ultraviolet light transmittance.
Reflects light and heat with a metal oxide coating giving a mirror finish.
Reflective glass adds daytime privacy with it's reflective, mirror-like surface.
Reflective glass can be tempered for added strength in certain industrial applications.
Applications:
Table top
Door windows
Double glazed window
Furniture and decoration
Superior performance to standard glass products
