Low e glass and smart glass windows


Smart glass or low e glass is also termed as smart windows or switchable windows due to its great applications. The use of smart glass is cost saving for heating, air-conditioning and lighting.It also avoids the set upcost. It is a new construction substance that is made from electro chromic glass to produce intelligent panels, windowpanes and skylights. The features of these electrically switchable surfaces are capable to modify their characteristics when an electric current is applied.

Smart glass is a range of single glazed toughened low e glass products, providing insulation solar shield with low efficiency perfectly suitable to the demands of built-up applications. Smart glass offers excellent performance and flexibility for single glazed windows.Low-e glass refers to low emissivity glass. This glass differs from ordinary plain glass in that one plain of the glass has a unique metal coating, technically known as a low emissivity or low e coating. Low e glass is a kind of shielding glass, which enhances the energy efficiency of glass window by dropping the transfer of temperature through glass. That means in the wintry weather your house keep warmer, and in the summer it remains cooler.As energy saving is considered most vital practice in our daily lives, practice to use low-e glass in our home will soon be a benchmark we all have to conform.

How Low E Glass Works:
As the letter “e” in low-e refers to emissivity that denotes power of producing radiant energy. A low-e coating emits nearly no radiant energy. This microscopic coating permits light to enter the glass, but obstruct most ultraviolet energy, which we experience as high temperature. Due to this characteristic low-e glass windows improve energy efficiency during high & low temperatures as:

In winter weather: Light is entered through the glass, but heat from innerplain is reflected back into the home by the low-e coating.
In summer weather: Light is entered through the glass, but heat from outer plain is reflected, serving to decrease cooling overheads.

Benefits of Low E Glass:
Enhanced energy efficiency:Low e glass reduces heat loss during winter months as well as reduces heat gain during the high temperature season.

Less UV harm: By blocking most ultraviolet (UV) emission, low e glass facilitate in protecting clothes, leather, floor covering and other items from the terrible fading effects of sunrays.

Reduced condensation:Formation of water droplets on the glass surface is one of the major problems. Low-e glass decreases unwanted condensation on window glass surface during the heating season.

In this way smart glass windows let home owners and business people manage the quantity of light that passes through their skylight. This changes the rate of heat transfer from the windows and works as a temperature control. Smart glass windows enhance the energy efficiency of any closed areadue to its capacity to decrease the need to generate energy to warm or cold your house or business area. This is a fairly innovative technology that assists to build an optimal set of scales and ease for the temperature in your home or work place.
