Abstract In this study, the feasibility of the application of flexible thin glass in greenhouses was investigated. With the development of thin but very strong glass plates like for mobile phones, new possibilities are being created for new greenhouse roof designs, the usage in multi-layered glass roof give possibilities for high-insulation greenhouse coverings. Flexible thin glass is a tempered glass. While standard tempered glass goes through a thermal process, this is a chemical process, which makes the glass five times stronger, creating the possibility of thickness reduction and bending. By adding nanocoatings the reflection can be reduced and the light transmission can be increased. Multi-layered greenhouse roofs can be created, resulting in a higher light transmission than currently available multilayer polycarbonate (PC) sheets, but also a higher transmission than today’s insulating double glass. The study shows that such glass combinations lead to an additional 20% energy savings based on heat demand for Phalaenopsis. Thin glasses are particularly strong and can also be used in curved form. This makes new greenhouse roof designs with these glasses possible. Especially the low weight offers advantages here. Important mechanical aspects and bottlenecks for the use in greenhouses have been mapped out. Due to limitations in today’s available dimensions and high prices, the use of thin glass in greenhouses will be further away in the future
