The glass facade has become an independent element of architectural expression after a long period of development and refinement. Among them, color expression is the focus of the artistic expression of glass curtain wall technology!
The absorption, reflection, and transmission of light by the glass is an important reason for its ability to present different colors. Tinted glass is manufactured according to this principle by adding different colorants to the glass raw materials, and its coloring is divided into propriety coloring and surface coloring.
To make colored facade glass, there are many kinds of processes, including digital printing, screen printing color glaze, Vanceva colored laminated, Sefar metal mesh laminated, tinted/colored glass, coated/coating glass, and so on. The first few processes are all surface coloring, while tinted/colored glass is body coloring.
With its flexible graphics and color expression, ceramic digital printing is often applied to the design of curtain wall glass effects such as multi-color, multi-coverage, and complex pattern puzzles.
The production process is to print inorganic high-temperature ink on the glass and then fix the ink on the glass surface at high temperatures.
Colored laminated glass is generally laminated (mostly PVB) material in the middle of ordinary float glass with the addition of colored pigments, colored film in Vanceva color performance is the richest.
Sefar Laminated Glass
It has a unique metallic texture and can be double-sided with different colors and transmission effects.
Tinted glass is intrinsically tinted glass. The vast majority of the single-piece window glass that many people think of as green, blue, bronze, gray, etc. is tinted glass.
Coating glass should be the most widely used glass product for facade glass color (such as the current variety of blue-gray, silver-gray and other Low-E coated glass). Its coloring principle is to coat the inner side of the outer glass of the curtain wall with a colored metal coating.
Tinted glass has a higher transmittance for visible light and a higher reflectance for infrared light. Ordinary colored glass has a visible light reflectivity of 20%-35% and a shading coefficient of about 80%, while coated colored glass products usually have a visible light reflectivity of 22%-80% and a shading coefficient of about 50%. The higher the reflectivity, the brighter the glass; the lower the shading coefficient, the less sunlight enters the room, the less heat can be generated, and the more energy-efficient.
