Lamination
Lamination process
Lamination is the process of creating two or more layers of glass structures by sandwiching EVA film between the glass. Laminating is preceded by cutting and subsequent other processing such as grinding, drilling, tempering, painting.
The laminated glass can be made of toughened/pre-strengthened or even annealed glass layers, which depends largely on the glass incorporation and previous machining. After lamination, the glass structure becomes secure, as in case of glass breakage, the broken glass layer is held by the film, so that the structure can remain intact.
Uses:
- railings
- stairs
- canopies, walkable slabs
- certain layers of insulating glass
EVA-PVB
Light transmission:
- EVA - 91%
- PVB - 89%
Free edge resistance: EVA is more resistant to moisture, prevents delamination at uncovered edges. With PVB, edges may show defects of a few cm.
Sound insulation: EVA provides better sound insulation than normal PVB.
Layer reduction: due to its fluidity, less EVA foil is sufficient for tempered laminated glass compared to PVB. Thus, with a thinner EVA foil we achieve a similar set of parameters but with a thinner glass structure.
