Thin Glass: The Market That Everyone Is Watching
Mar 28, 2026
The most active discussion among equipment manufacturers at the last major glass industry exhibition centered on thin glass processing. Thin glass, defined here as material under 2.0mm, has been used in consumer electronics for years, but its migration into architectural and automotive applications is forcing OEMs to reconsider their furnace configurations.
The problem is that traditional roller-hearth tempering furnaces cannot process thin glass without leaving roller wave distortion-a subtle undulation that becomes highly visible in reflective architectural facades. The solution has been either chemical strengthening, which requires ion-exchange bath lines and involves longer cycle times, or advanced convection furnaces that float the glass on air rather than rollers.
Several architectural OEMs in Southeast Asia and Turkey have begun installing these convection lines specifically to target the balcony balustrade and shower enclosure markets, where thin glass offers weight savings and a cleaner aesthetic. Whether this capacity expansion becomes oversupply depends on whether architects actually specify thin glass at scale, or whether it remains a niche application for high-end residential work.
