Heat Insulation Triple Silver Low E Glass Curtain Wall for Commercial Building

Australia Standard Heat Insulation Triple Silver Low-E Glass Curtain Wall Commercial Building

Low-E glass, also known as low-emissivity glass (Low Emissivity Glass), is a film-based product composed of multiple layers of metal or other compounds plated on the glass surface. The main functional layer of the Low-E film is the silver layer. Silver is one of the substances with the lowest emissivity in nature. Coating a nano-level silver layer on the surface of the glass can reduce the emissivity of the glass from 0.84 to 0.02~0.12. Filter sunlight into a cool light source. The coating layer has the characteristics of high transmission of visible light and high reflection of mid- and far-infrared rays, thereby filtering sunlight into a cold light source, which not only meets the requirements of natural lighting, but also ensures a comfortable room temperature.

Specification:

Optical parameters: On the premise of the same light transmittance, double silver and triple silver Low-E glass have lower shading coefficient Sc and heat transfer coefficient U (see the table below), double silver and triple silver Low-E glass are lower than single silver Low-E glass can block more solar radiation heat energy and maximize the filtering of sunlight into cold light sources.

Indoor comfort: Low-E glass can greatly reduce the heat exchange through the glass in the indoor and outdoor environments, so when the air conditioner is cooling or heating, after the indoor temperature reaches the set temperature, the air conditioner can be on standby for a longer time status, thereby saving power consumption. Not only that, the shading characteristics of Low-E glass greatly reduce the time of using curtains to shade, thus improving indoor light comfort and creating a more transparent and bright indoor environment. To make a simple example, in summer, the effective operation time of air conditioning and refrigeration for buildings with ordinary glass is 100 days, and the effective operation time of refrigeration after using single silver Low-E glass is shortened to 35 days, and if double silver is used Or triple silver Low-E glass, it only takes about 30 days or less, further saving electricity bills. In the long run, although the use of double and triple silver Low-E glass increases the construction cost of the project by a small amount, it greatly reduces the energy consumption cost of the building during its use period.

The advantages of triple silver Low-E glass are that the visible light transmittance is higher than in the past, which can make the room have enough sunlight; the solar infrared heat transmittance is low, and the heat transfer coefficient is also lower, which can effectively heat insulation.
