Energy loss is evident in the macro national economic system. Saving energy in buildings is an important issue now, but it will be even more important in the future. The study found: over 45% of energy from buildings is lost through doors and windows, and therefore energy saving doors, windows and glass walls are an important issue in the development of glass industry.
Glass doors and windows are the primary means of communication in building’s interior and exterior. Lighting, view, decoration are the basic requirements for glass, energy saving and environmental protection are additional requirements for glass doors and all that leads to community increase. With closed windows in the transfer of air in closed rooms, the exchange of indoor and outdoor energy passes through a glass window. Big exchange of outdoor and indoor energy causes more heat in summer and less heat in winter. This leads to great loss of indoor energy, as well as extensive use of air conditioners. Insulating glass is a great solution to this problem, and at the same time saves energy, protects environment, increases comfort and creativity of life.
Insulating glass is manufactured through sealing two or more sheets of glass (or glass with coatings with tendencies to replace regular float glass) with sealants of exceptional strength. Partitions of aluminum alloy with drainers filled between the sheets of glass make the air inside the glass very dry, butyl rubber seal is used as the first line, and as the second seal we’re using glass or plastic polysulfide adhesive on the basis of used glass framework. The space between the sheets of glass is insulated from the outside with sealants and special gas. Insulating glass has good performances in heat and noise insulation.
Insulating glass is filled with special gas by the process of rapid vertical charge with Argon gas, krypton gas and other inert gases. In this way insulating glass effectively reduces the thermal conductivity and provides air and water tightness of glass and longer lifetime of glass products.
Insulating glass system is a type of filled hollow glass curtain that has become popular in the world in the 1990s. In our country this system is applied on top buildings since middle 1990’s.Glass curtain (wall) with the supporting point without the frame gives the building very low permeability and very good visual effect.
The insulating glass system has higher requirements for companies engaged in deep glass processing.
Low-E glass filled with insulating gas: LOW-E glass film can effectively block radiant heat. Low-E glass filled with gas can further reduce the direct transmission of thermal energy and greatly reduce conduction of heat through the window. For example, the U value of common hollow glass with same specification is 3.0 W/m².K, reducing 67%.
In order to produce LOW-E glass insulation, companies engaged in deep glass processing must satisfy all the imperative requirements. We meet European standards in the processes of cutting, grinding, cleaning, drying, toughening , film and edges removing, bending of aluminum division bar and automatic molecular charging and sealing.
Insulating glass features:
1. Good insulation characteristics (U Value for ordinary insulating glass (U= thermal conductivity) is up to 3.0 and 5.8 for monolayer glass), can largely cut energy consumption.
2. Low moisture permeability keeps indoor temperature and prevents freezing of the glass.
3. Condensing temperature of glass is up to -50 ° C, can reduce outdoor noise of 30 dB.
4. Good anti-aging properties, lifetime more than 10 years
