Low E Glass

Low-Ecoating stands for Low-emittance coating on a solid surface. It is an extremely thin, nearly invisible film of metal or metal oxide layers deposited on a window or skylight. Its primary function is to reduce U-factor by restricting radiative heat flow. The key methodology by which heat is transferred in multilayer glazing is thermal radiation from a warm sheet of glass to a cooler sheet. Covering a glass surface with a low-emittance element and placing that coating into the gap between the layers of glass impedes this radiant heat transfer significantly, thus reducing the overall flow of heat through the window. Benefits of Low-E Glass Low-E technology is over two decades old in the glass market. Although its benefits have been duly acknowledged, glass with low-e coating is rarely used in construction. There are several priceless advantages and cost savings that can be achieved by using low-e glass. During the severe energy crisis the world faced during the 1970s, everyone endeavoured to minimize consumption of natural resources. In case of glass, energy was lost by way of heat loss through the glazed surface. In 1980, the commercial development of thin, transparent, low emissive coatings literally revolutionized the concept of energy savings in windows. The low-e coating, placed on the inside of the insulating glass unit, enabled the sun^s short-wave energy to enter the room and at the same time prevented internal warm air from leaving the room.

Available in different dimensions and thickness, our low emission glasses can be customized for our clients as per their specific requirements. We are offering our clients with a wide range of low emission glasses that is used for designing greenhouses. These low emission glasses are coated with a microscopically thin layer of metal oxide that allows the heat and light of sun to enter the building and blocks it escaping from the building, thereby creating a thermal insulation, and reducing the carbon footprint of the building.

Low-E glasses are coated with microscopically-thin, optically transparent layers of silver which is further sandwiched between layers of anti-reflective metal oxide coatings. Low-E glass products lets in visible sunlight while blocking infrared and ultraviolet solar energy that drives high cooling costs and damages the window treatments, carpeting and furnishings in the hot weather of summers. And in winters, Low-E glass products offer greater comfort and reduce heating costs by reflecting heat back into the room. Nowadays, people prefer large-size window for sightseeing or enjoying sunshine to relax. "It is not easy to make the best of both worlds"! But, the low-E glass comes with the solution. It has a high transmission of visible light and can reflect infrared heat at the same time.

Government Building Regulations require us to save energy, to help protect the environment. Using low-E glass is the most efficient way of doing this with glazing. This also provides benefits to you as a property owner as money can be saved on heating bills as heat loss is reduced by a massive 75% compared to single glazing and at least 40% compared to traditional double glazing. Rooms are also more comfortable as cold spots near windows and drafts are reduced. Finally unsightly condensation on the inside of the glass is reduced beacuse the temperature of the interior pane is kept closer to room temperature.

With the help of adroit team, we present an extensive series of Window Low E Glass. Our products are available in varied specifications that meet on consumer s demand.

Low-E Glass Tempering: Quality and Technology RequirementsLow-emissivity (low-e) glass has been available since the early 1990 s. However, only recently have many global manufacturers started promoting these glasses in India. With the advent of low-e glasses along-with solar control properties, or hybrid glasses, such brands are becoming popular in a hot country like India. Leading among these brands are the SunergyTM series from Glaverbel, or the Eclipse Advantage TM series from Pilkinton, or the Ecologic TM series from Saint Gobain. Tempering of low-emissivity glasses poses significant challenges, and is quite different from tempering of clear and tinted glasses. Clear and tinted glasses have rather high emissive levels and absorb heat inside a furnace very well. Until recently tempering of low-e glasses was done in a similar manner as for clear & tinted glasses. The standard workhorse was the radiation type furnace, much like the electric rod heater in the room. Low-e glasses are designed to reflect heat and by design do not absorb radiation heat inside the furnace evenly. This creates several quality problems like 1. Bending in glass 2. Distortion 3. Lower strength & uneven fragmentationThe latest advance for tempering low-e glass, has been the advent of the Forced-convection tempering furnace. In a forced -convection furnace glass is heated indirectly through hot air jets in addition to radiation. Heat-exchange inside the convection furnace is through hot air rather than only radiation, which is reflected by the low-e coating on glass. Just like a fan and an air-conditioner cool the room more evenly and faster, forced convection heating is far more even, addressing most of the quality issues above.Can low-e and other reflective Glasses be tempered on the ordinary radiation furnace?Tempering Low-e and other reflective glass can be done on radiation furnaces. However, the heating of the glass is extremely slow because these glasses reflect majority of the radiation, and only absorb heat very-very slowly. In such cases, glass spends a lot of time oscillating on rollers in its softened state (600-675 C) waiting to reach its desired temperature for tempering. This results is significantly more roller-wave distortion in the glass. In forced convection heating, majority of the heating is done through the exchange of heat between the hot air molecules and the glass. Consequently the heating is much faster and glass spends less time in its softened state on the rollers, resulting in much lower distortion.Disadvantages of Forced ConvectionThere are three negatives of forced convection tempering. First, it is difficult to control the convection currents inside the furnace and requires proper design in the equipment and operator skill. Secondly, forced convection tempering consumes about 10% more electricity due to indirect heating through air-jets. Additionally, forced convection machines are also more expensive to buy as well as maintain. Attachments1.Low-e glass tempering, by Jorma Vitkala, 1997 2.
