Low - E glass, a breakthrough in manufacturing technology of Viglacera

Always a leading company, positively in research and applying the world class of modern science and high technology in production of building materials, VIGLACERA is again making a breakthroughs in technology, while actively investing in project of "Low – E glass production lines"- This project was approved as "high technology" project by the Prime Minister on January 13, 2015.

Intended capacity of Scale 5 million m2/year, the project includes two phases of investment: Phase 1: production line with the capacity of 2.300.000m2/year at Tan Dong Hiep - Di An - Binh Duong; and Phase 2: production lines with the capacity of 2.3 - 2,7 million m2 / year at Bac Ninh province.

Using Low-E glass is the solution for building’s energy saving, protecting the health of users and also a solution to the investment efficiency

Low - E glass is kind of high-performance glass, using the float glass as substrate with ultra-thin coating layer on the surface, high ability to conform the requirements of usability, transparency requirements and the color of the glass, and also low emissivity feature, small coefficient of thermal conductivity, resulting in minimized of transfering the temperature between inside and outside environment through glass wall system, thereby saving energy costs of air conditioner system however, still can maintain the cooling effect in the summer and heating in winter.

Most countries around the world are using Low-E glass with the soft coating of production technology. Because the soft coating glass has advanced features compared to hard-coated glass. In order to meet Vietnamese’s climate conditions and the world’s trend, VIGLACERA also applied the soft coated technology to both Solar Control and Low – E glass products for its "Low-E production line”.

The principle of operation of Low-E glass

Solar Control glass is coated by metallic coating layers non-containing silver, thus could be installed single layer without affecting to the coating reliability. Solar Control glass is capable to prevent the amount of light that the human eye can take from sunlight that reaches about 5 - 95%; for energy from sunlight up to 79% and especially with the ultraviolet lights, the ability to prevent up to 99%. Besides the basic features as Solar Control glass, Low-E glass is coated by silver layer, and have features consistent with the cold weather. Low-E glass ensures that most of the sunlight that human eye can take to illuminate the inside of the house and avoid the loss of temperature from the indoor to the outdoor environment.

Thus, if the glass Solar Control saves energy by reducing the temperature from outside to the house to minimize the cost of using the air conditioner to cool the room, by contrast, Low - E glass saves energy by reducing energy consumption from the uses of heater to warm the room. With this advanced characteristics, Low-E glass of Viglacera will satisfy both hot and cold climates.

Many large building on world are using and promoting radical premium features of Low-E glass

Currently, most of the large buildings on the world are using Low-E glass and the Vietnamese’s big investors also started to use the Low-E glass. In fact, these glasses are not only brings comfort optimizer and enhance the value of the building, but also bring greater efficiency, effectiveness in long-term for Investor Owners. Even in many developed countries have formaly required to use the environmental friendly materials for the building by the law. As assessed by the leading experts in construction, using Low-E glass will bring the solutions to the energy saving efficiency for buildings.
