What Is Tinted Glass?
Tinted window glass (known more formally as tinted window glazing) is not the same as the synthetic, tinted films commonly applied to the surface of clear glass windows in vehicles, homes and businesses. Instead, this product has a color or tint added directly to it during the float glass process before cooling. This means that the chosen tint permeates throughout each sheet of finished glass, rather than just remaining on the surface. Since the tint is literally a part of the glass, it will not rub off with use or peel away like a tinted synthetic film.
Depending on the color and amount of tint used during the manufacturing process, tinted window glass may be substantially darker and more opaque than clear glass. As a rule, thicker panes of glass appear darker than thinner panes with the same tinting amount and color. From the inside, tinted windows still provide a clear view, even when they reduce visibility from the outside. Since tinted windows absorb a lot of heat (which can potentially cause problems with their structural stability), they’re typically made from single-layered tempered glass or multi-layered laminated glass, not weaker, traditional annealed glass.
