Double Silver Low-E Glass Curtain Wall Saving Energy Consumption and Efficient Heat Preservation

Product description:

Glass is an amorphous inorganic non-metallic material. It is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw material, and a small amount of auxiliary raw materials are added. of. Its main components are silicon dioxide and other oxides. The chemical composition of ordinary glass is Na₂SiO₃, CaSiO₃, SiO₂ or Na₂O·CaO·6SiO₂, etc. The main component is silicate double salt, which is an amorphous solid with irregular structure. It is widely used in buildings to separate wind and transmit light. It is a mixture. There are also colored glass that is mixed with certain metal oxides or salts to show color, and tempered glass made by physical or chemical methods.

Any coated glass restricts the transmission of visible light to varying degrees while restricting the transmission of solar heat radiation. Double-silver Low-E glass can block more solar heat radiation heat energy than single-silver Low-E glass. In other words, under the same light transmittance, Double Silver Low-E has a lower shading coefficient Sc, which can filter sunlight into a cold light source to a greater extent.

The heat transfer coefficient of double-silver Low-E glass is lower than that of single-silver Low-E, which can further improve the thermal insulation performance of external windows, and truly achieve warm in winter and cool in summer. Simply put, because the double silver Low-E glass greatly reduces the heat exchange between the indoor and outdoor environments through the glass, when the air conditioner is heating or cooling, the air conditioner can be longer after the indoor temperature reaches the set temperature The time is in the standby state, thereby saving power consumption.

Optical parameters: Under the premise of the same light transmittance, the double silver Low-E has a lower shading coefficient Sc and heat transfer coefficient U. The double silver glass can block more solar radiation heat than the single silver Low-E glass. Filter sunlight into a cold light source to the greatest extent. In the long run, although the use of double silver Low-E glass increases a small amount of project construction costs, it greatly reduces the energy consumption during the life of the building, and the later energy saving can recover the investment in a short period of time. Increased cost.

Specification:

Advantage:

1. Under the same glass combination, double silver Low-E glass has lower emissivity and lower heat transfer coefficient (U value) than single silver LOW-E.

2. Double silver Low-E glass has a lower shading coefficient or Sc value.

3. When the shading coefficient (Sc value) is the same, the visible light transmittance is higher than that of single silver Low-E. In short, the double silver Low-E glass highlights the shielding effect of the glass on solar heat radiation, and cleverly combines the high light transmittance of glass with the low transmittance of solar heat radiation, and successfully solves the problem of high light transmittance. It is difficult to coexist with the dual advantages of low U value and Sc value, so it has a better energy-saving effect, which is an advantage that any other glass cannot have.

Application:

As the country attaches importance to energy conservation and environmental protection policies and people's awareness of energy conservation, energy-saving and comfortable Low-E glass will be more and more widely used in buildings. Understanding Low-E glass, using real Low-E glass, and using appropriate Low-E glass have become an important aspect of current architectural design. In addition, the selection of glass is also a complicated issue. Different types of Low-E glass are used in different regions, and the use surface of Low-E glass is different whether it is used indoors or outdoors. Only the reasonable use of Low-E glass In order to fully reflect the energy-saving performance of Low-E glass.
