Laminated glass is a type of safety glass that is produced when two or more layers of glass (between which there is a safety film that holds the glass during fracture as a whole) are connected under pressure and temperature in the oven for laminating. Laminated glass has multiple applications and can serve as a floor (steel galleries with glass as tread), partition (glass windows or balconies) or protective surfaces (such as bulletproof glass that is used at exchange counters and banks).
Application of laminated glass, looking from a safety aspect, has become increasingly important in modern design. Modern designers and architects agitate for the installation of glass with less visible details as freestanding fences or glass facades on spider beams, so in these cases laminated tempered glass is used. It is possible to combine tempered glass with non-tempered, or two semi-tempered glasses, and the reason is the complete safety of overhead glazing (canopies, glass roofs, floor laminated glass), and stair steps.The maximum size of double laminated glass, which we possess is 6000 x 3210m, while the maximum dimension of laminated glass with EVA (ethylene-vinyl acetate) foil that we can currently produce in our laminating furnaces 1950 x 2950 mm. The thickness of intermediate layers may be 0.40 mm 0.80 mm 1.20 mm 1.60 mm; .... , and the combination of glass according to customer`s wishes (eg, colored glass with a transparent, three-layer glass which has a middle glass broken ...).
Basic technical characteristics of EVA (ethylene-vinyl acetate) films: • adhesion strength of glass-glass ……………………………. 14 N/cm2 • tensile strength of films ……………………………….….. 190 N/cm2 • transmission of light ………………………………………………….< 87% EVA film is made with a high factor of networking which makes the intermediatelayer resistant to moisture and temperature after the lamination, and is suitable for making glass used in the exterior where the edge of the laminate is exposed to weather (the spider mounting brackets, etc..) EVA foil is, due to its low viscosity during lamination, extremely suitable for laminating tempered glass and glass having uneven surfaces. Likewise, a lamination with EVA foil there is a possibility of combining with other materials between glass (PVC, PET, POLYKARBONAT, Acrylic, etc.).
