Our product portfolio comprises clear glass, 22 kinds of value-added glass products and 11 kinds of processed glass products, of varying thickness between 2 mm and 12 mm. Our products cater to a range of end use industries including construction, automotive, and industrial sectors, with a variety of applications such as exterior and interior spaces of residential and commercial buildings, furniture, infrastructure projects, windshields, sun-roofs, and white goods. We produce a range of value added glass products including frosted glass, mirrors, tinted glass, solar control reflective glass for a wide range of applications. We also produce processed glass such as toughened glass, heat-strengthened glass, ceramic insulated glass, PVB laminated glass, and bullet-resistant glass among others. As of December 31, 2021, our product portfolio included clear glass, 22 kinds of value-added glass and 11 kinds of processed glass, with varying thickness between 2 mm and 12 mm.
The most common type of glass is manufactured by melting sand. Other ingredients such as soda ash, limestone, salt cake, and broken cullet glasses are added to lower the melting temperature of silica and promote optical clarity of the finished glass product. A mixed batch of the above materials is heated to high temperature and formed into large flat sheets by floating molten glass on the molten tin, thus giving it precise flatness and transparency. The clear float glass has a standard thickness between 2.5 mm to 12 mm and its characteristic includes reflectance, transmission, and absorption.
Frosted glass has a very neat, clear, and glossy surface. One of the surfaces is frosted or obscured by blasting sand or abrasives under high pressure through a nozzle. A very thin layer of material is removed and the sand or abrasive causes pitting on the surface obscuring its ‘see through’ property but not obstructing the passage of light. The final glass is known as frosted glass which can then be used across multiple applications and can be added on top of any of the other variants of clear or value-added glass to increase their aesthetic appeal.
Mirrors are manufactured by applying a reflective coating to a suitable substrate that almost exclusively is just glass, and reflective coating is typically silver or aluminum. Because metals oxidize, they can be additionally coated with some tin chloride or paint. We have three variants of mirrors in our product portfolio, i.e., clear, grey and bronze. Clear mirror is largely has residential and automotive applications while grey and bronze variants have interior applications.
It is a normal flat glass to which color is added during the manufacturing process to achieve tint and solar radiation absorption properties. These properties help diminish energy transmissions through the glass when exposed to strong sunlight. Variations in the thickness of the glass would yield different performances in terms of light and solar transmission. In the tinted glass series, we have blue, grey, bronze, and green colors which we call an ‘Optimystic Tinted’ series. Further, this variety of glass keeps the interior cool, reduces power consumption, and protects from harmful ultra-violet rays. Tinted float glass has architectural application in windows or facades and is also used for interior partitions and tabletops/furniture as well as in the automotive sector.
Solar Control Reflective Glass
Solar control reflective glass is meant to reduce heat from solar radiation. Online coated float glass is also a basic clear or body tinted float glass that is coated with a thin inorganic material at high temperatures. Reflective float glass is produced by applying a special pyrolytic coating to clear and tinted glass which works by reflecting heat instead of absorbing it. With a lower solar factor as compared to ordinary clear glass, ‘Optimistic Reflecta’ solar control glass is able to reduce the heat transmission while letting in optimum light coming into the building which makes it ideal for tropical countries. Further, this variety of glass keeps the interior cool and reduces power consumption.
Toughened or Tempered Glass
In this process, glass undergoes a process of controlled thermal treatment to increase its strength. Regular glass is exposed to high heat and then rapidly cooled by a blast of air blown through nozzles on both sides of the glass in the quenching chamber. It is prepared by completing prior to its tempering, all such works in accordance with drawings, sizes and templates.
This process of heating and rapid cooling makes it stronger than the annealed glass and enhances safety since it breaks into circular chunks reducing the risk of injury. Further, it does not alter the light transmission and solar radiant heat properties of the glass and cannot be cut, ground, drilled or worked upon.
Heat Strengthened Glass
In this process, glass undergoes a process of controlled thermal treatment to increase its strength. Regular glass is exposed to extreme heat then cooled down at a slower pace. The residual stress on the edge and the glass surface differ in both cases with tempered glass having a higher level of stress. Further due to such a process, the mechanical and thermal strength of the glass is increased by making it stronger than annealed glass and making it appear comparatively flatter than tempered glass giving it fewer optical distortions. Due to such characteristics, it can be used in situations that require more optical clarity and in high wind load areas.
This glass is constructed by two or more glass panes bonded together with interlayers of polyvinyl butyral (“PVB”) or ionomers between them and then treated and is generally used for safety and security purposes since the PVB layers make the glass layers stick to them so that it does not fall out of the window frame. The glass panes can be annealed float glass, toughened glass, or heat strengthened glass. The most common use of laminated glass is for front windscreens of automobiles and can also be used in architectural applications due to its characteristic of being safe, secure, acting as a barrier to noise, reducing the ultraviolet rays from the sun thereby protecting interior furnishing and fire retardancy.
Insulated glass combines two or more glass panes that are spaced apart and sealed with a sealant to appear as a single unit. Also known as Double Glazed Unit or Hermetically Sealed Unit or Vacuum Glass or Sound Proof Glass, these glasses are designed to improve thermal performance and reduce energy costs and act as a good insulator, reduce sound transmission, prevent condensation of dew, and offer energy conservation.
Bullet Resistant Glass
Bullet resistant glass is a strong but optically transparent material that cannot be penetrated when struck. However, they are not completely impenetrable. This glass is built up to protect people against firearms. The ability of bullet-resistant glass to stop a bullet is determined by the thickness of the glass.
