Iph Tempered glass is approximately 4 to 5 times stronger the annealed glass of the same thickness. It meets the entire safety standard. Toughened glass can be made from annealed glass. The glass is placed on a roller table taking it through a furnace that heats it above its annealing point of about 720 C. The glass is then rapidly cooled with forced air draft while the inner portion remains free to flow for shor time. At the time of broken Tempered glass fractures into small cubes (fragments). It helps to reduce serious injury as compared to annealed glass. when annealed Glass is breaks into larger Cube and edges are very sharp. When the glass breaks it breaks apart into thousand of small fragments with out sharp edges. It can be used in structural glazing, windows, shower cabins, sliding doors, furniture frameless door etc.
Laminated glass is a type of safety glass that hold together when shattered. Laminated glass is two or more glass sheets joint together with an inner layer of polyvinyl butyral (PVB) film to which the glasses adhere to under specific heat and pressure conditions. The glass panes can be annealed, tempered glass, heat strengthen glass, tinted glass or Reflective glass. Glass panes can be varied by changing the number and thickness of each glass. Sandwich glass look like a single glass. The pressure and the temperature during manufacturing are so high that the PVB layers are permanently connected to the glass. Laminated glass is durable, high performance and multi functional benefits. Laminated glass does not shatter like ordinary glass the tough clear inner layer absorb impact resist penetration and remain intact even if broken holding glass fragments in place and lower the risk of injury. PVB laminated glass is used where safety or security requires, for noise control, solar control, UV screening, Bullet resistance. Reflective and laminated glass can be reduce heat gain, control glare and lower air conditioning expenses. Laminated glass is manufactures with UV absorbing additives that can reject 99% of the UV light within a band of 200-380 nanometer wavelengths, without affecting visibility and plant growth.
