Ceramic Fritted Glass

Ceramic silkscreen painted glass is commonly used for spandrel glass and areas of a facade where a printed design is desired.  Paint is applied to clear, tinted, patterned or reflective glass - only pyrolytic glass though.  For a glass to be heat treated after coatings are applied, it needs to be Pyrolytic.  The paint is applied by silkscreen print, digital printer or roller/curtain.  After paint is applied, the glass is then tempered or heat strengthened which fuses the paint to the glass to create an integral and durable coating.  The final product might then be laminated for use as overhead glazing.  The opacity of frit can improve shading and reduce heat gain.  However in comparison to exterior architectural shading devices, frit typically offers only minor reduction in solar heat gain.

Several similar names are used to refer to this process:

• Ceramic Base Painted Glass
• Ceramic Fritted Glass
• Colourclad Glass
• Ceramic Backed Glass
• Opacified Glass
