Laminated glass is a modern durable and safety material that our Gray Glass uses for production of glass visors, partitions for homes and offices and excellent glass railings.
The main quality of a Laminated Glass is that, when broken, it does not shatter into fragments, it remains in the rear structure. Laminated glass is one of the most popular types of glass when choosing a material for production of various glass structures. Its considerable popularity is due to its high strength, which contributes to greater security from the attack of robbers and resistance to storms. In addition, this glass has excellent soundproofing properties.
Laminated glass consists of two or several sheets of glass with special PVB interlayer between them. PVB, or polyvinyl butyral, is a thermoset, one-component, polymerizable adhesive that can be used as a conventional adhesive.
The choice of such a material is optimal to use for safety purposes, since the glass does not break upon impact, but “sticks” in the PVB interlayer. Thus, this eliminates damage from fragments, the risk of a person falling through the glass, and if the glass facade is damaged, it will not fall until it is replaced with new glass.
In addition, laminated glass provides a high level of protection against hurricanes, burglar attacks, bombs, bullets and other troubles. It blocks out 99% of UV radiation, preventing the inner padding from fading. Among the advantages of laminated glass there are the following factors: low visual distortion, moderate heating, low glare, and high soundproofing.
Laminated Glass is more than just a few pieces of glass “glued” together, they become one piece during processing. Chemical bonds are established between PVB and glass, and completely new material is created, which gives the laminated glass its properties, since the synergy of the complex of materials is stronger than the sum of the individual components.
There are many different myths about laminated glass. Due to the high cost and frequent unavailability of laminated glass, not all industry enterprises are aware of the manufacturing technology of this product, and therefore myths are born about its instability and insufficient strength. But laminated glass is by no means inferior in strength to ordinary glass of the same thickness. Moreover, laminated glass is made in such a way that it is highly resistant to strong wind gusts.
Another myth about laminated glass is that the glass delaminates easily. Such an outcome, of course, is possible, but non-compliance with the norms and order of the manufacturing and sealing process leads to it. Conventional laminated glass is not recommended for point-fix structures or squash or tennis courts. In this case, it is better to use tempered laminated glass. When using high quality light absorbing glass (reflective, super-tinted glass), there is a possibility of heat damage. In such cases, some requirements must be met:
laminated glass must be fixed on at least two sides; it is necessary to install 3 or even more drain holes at the bottom of the frame; it is not recommended to use material for insulating seams of organic origin, since this is fraught with the discharge of PVB along the edges of the sheet; the glass may be cut on site during installation, but it is worth making sure the edges of the frame remain clean.
Laminated glass, as well as tempered glass provides safety. Both of these types of glass can protect against serious damage, but laminated glass is still more optimal in life-threatening situations. Since when tempered glass is damaged, it is crushed into many small pieces that can scatter in all directions and injure others, as a result of which superficial injuries are possible.
Laminated glass provides a greater level of security, because glass shards stick to the PVB layer instead of flying apart, eliminating the risk of injury to those present.
Another benefit of laminated glass is that with PVB interlayer, the glass blocks UV rays and thus prevents fabrics, furniture, coatings, etc. from glare. Fading is caused by UV rays, radiation, sunlight and temperature. Properly selected glass can block up to 99% of UV rays from passing through. As a result, laminated glass is in high demand in shop windows and homes around the world.
