Product Description

Single Silver 6mm + 12A + 6mm Low-E Glass Curtain Wall With Low Heat Transfer Coefficient

Product description:

Single-silver Low-E coated glass usually contains only one functional layer (silver layer), plus other metal and compound layers, the total number of film layers reaches 5 layers. Excellent thermal performance The heat loss of external doors and windows is the main part of the building's energy consumption, accounting for more than 50% of the building's energy consumption. Relevant research data show that the heat transfer on the inner surface of glass is dominated by radiation, accounting for 58%. This means that the most effective way to reduce the loss of heat energy by changing the performance of the glass is to suppress the radiation on the inner surface. The emissivity of ordinary float glass is as high as 0.84, when it is coated with a low-emissivity film based on silver, its emissivity can be reduced to below 0.15. Therefore, the use of single Low-E glass to manufacture building doors and windows can greatly reduce the transmission of indoor heat energy caused by radiation to the outdoors, and achieve an ideal energy-saving effect. Another significant benefit brought by the reduction of indoor heat loss is environmental protection. In the cold season, the emission of CO2, SO2 and other harmful gases caused by building heating is an important source of pollution. If single Low-E glass is used, due to the reduction of heat loss, the fuel consumed for heating can be greatly reduced, thereby reducing harmful gas emissions.

The heat passing through the glass is bidirectional, that is, heat can be transferred from indoor to outdoor, and vice versa, and it is carried out at the same time. It is only a problem of poor heat transfer. In winter, the indoor temperature is higher than the outdoor temperature, and insulation is required. In summer, the indoor temperature is lower than the outdoor temperature, and the glass is required to be insulated, that is, as little outdoor heat as possible is transferred to the indoors. Single Low-E glass can meet the requirements of winter and summer, and it can keep heat and heat insulation, and has the effect of environmental protection and low carbon. The visible light transmittance of single Low-E glass ranges from theoretically 0%-95% (which is difficult to achieve with 6mm white glass), and the visible light transmittance represents indoor lighting. The outdoor reflectance is about 10%-30%. The outdoor reflectance is the visible light reflectance, which represents the intensity or dazzling degree of the light. So far, China requires that the visible light reflectance of the curtain wall is no more than 30%.

Specification:

· Visible Light Transmittance: The higher, the brighter the interior will be the lighter the glass color will be.

· Visible Light Reflectance: The higher, the more reflective the glass will be.

· U-Value: The lower, the better heat insulation performance will be.

· SC/SHGC: The lower, the less solar heat transfers to indoor.

Advantage:

Single silver Low-E glass can greatly reduce the heat exchange between indoor and outdoor environments through the glass. Therefore, when the air conditioner is cooling or heating, after the indoor temperature reaches the set temperature, the air conditioner can stay in standby for a longer time. Thereby saving power consumption. Not only that, the shading characteristics of single silver Low-E glass greatly reduce the time of using curtains to shade, thereby improving indoor light comfort and creating a more transparent and beautiful indoor environment. As a simple analogy, in summer, a building with ordinary glass originally required air-conditioning and cooling for an effective operating time of 100 days, but after using single-silver Low-E glass, the effective operating time for cooling required was shortened to 35 days, further saving electricity bills.

Application:

Single-silver Low-E glass is widely used in building curtain walls and large-area windows to meet the dual characteristics of lighting and energy saving. Generally not used as a single piece, usually combined into gas-filled hollow glass or vacuum glass. The hollow cavity is filled with inert gas such as Ar or Kr to protect the glass membrane surface from damage and prolong the service life of Low-E glass. , Improve the energy-saving effect of glass.
