Iranian Firm Manufactures Energy-Efficient Nano Glass
Kaveh Glass Industrial Group has been able to produce energy controlling glass called EcoStar and EcoStar Plus using nanotechnology and receive a NanoScale Certification from Product Evaluation Unit of Iran Nanotechnology Innovation Council (INIC). EcoStar and EcoStar Plus products are industrially manufactured and currently available in the market.
Energy controlling glass controls energy transmission through conduction and radiation simultaneously and makes glass into an extremely effective element to reduce energy consumption, increases brightness, and provides visibility in the building, enhances the beauty of the façade while maintaining visible light transmission. These types of glass windows help materialization of the idea of buildings with large windows that bring inside light and beauty of the surroundings.
Kaveh's EcoStar Glass is a colorless energy controlling glass that is produced by the soft coat method. The metal oxide coating is deposited under vacuum conditions on the glass surface by a sputtering method and this coverage reflects short and long IR waves.
The appearance of EcoStar Glass is like ordinary double glazed windows and performs the same function in both light reflection and light transmission modes.
It can enhance the performance of Kaveh’s EcoStar Plus by using it with other types of glass to create sound insulation, safety and security, decoration and privacy insulation.
The heat insulation of EcoStar double glazed windows are up to three times more efficient than ordinary double glazed windows and this feature offers many advantages such as preventing heat loss, reducing the environmental impact of energy consumption to provide heating and avoiding condensation during the cold seasons of the year.
Also, given that this type of glass is more than twice as efficient as ordinary glass windows for blocking the sunlight heat, it has advantages such as greater thermal comfort in the summer and lower costs for cooling facilities. In addition, these types of glass block the entry of solar ultraviolet radiation.
EcoStar Plus Low-E is manufactured by deposition of one or two silver layers on the glass surface under vacuum condition and with nanotechnology.
Standard clear glass has an emittance of 0.84 over the long-wave portion of the spectrum, meaning that 84% of the long-wave radiation striking the surface of the glass is absorbed and only 16% is reflected; but Low-E glass coating has an emittance as low as 0.04. Such glazing would reflect 96% of the incident long-wave and infrared radiation, it would allow most visible light through, but would block all other portions of the solar spectrum, including ultraviolet and near-infrared radiation and minimize summer heat gains. Low-E coatings on EcoStar Plus glass, by reflecting infrared energy would reduce the absorbed or lost heat of the building through changing the direction of the heat radiation.
EcoStar Plus glass products keep the best balance between passing through visible light and controlling the sun’s energy and they have the highest visible transmittance compared to the ordinary reflex coatings.
This product is used in a variety of demanding applications, including commercial buildings (office, hotel, shopping center, airport, etc.), light-absorbing spaces such as greenhouses that require low light or solar reflectance and also residential buildings and all structures that need the use of safety or security glass windows.
The EcoStar Plus glass with its energy-saving stability guarantees warmth in winter and cold in summer and is a great choice for hot and cold climates. Considering the high energy-efficient low-E coatings increase building efficiency by reducing energy consumption, this industry has a high return on investment in the future.
