Low e glazing

What is the purpose of low-E glass? Why to get a window with low-E glass? Low-E coatings have been developed to minimize the amount of ultraviolet and infrared light that can pass through glass without compromising the amount of visible light that is transmitted. When heat or light energy is absorbed by glass, it is either shifted away by moving air or re-radiated by the glass surface.

By comparison , low-E glass coatings can have an emittance as low as 0. Such glazing would emit only of the energy possible at its temperature, and thus reflect of the incident long-wave, infrared radiation. Low-E , or low-emissivity , glass was created to minimize the amount of infrared and ultraviolet light that comes through your glass , without minimizing the amount of light that enters your home. The coating is even thinner than human hair!

Moderate solar gain low e coating is often referred to as soft coating. This glazing treatment significantly reduces heat loss while also moderately reducing unwanted heat gain. This energy saving window coating is well designed for climate zones where both heating and cooling are significant concerns.

Low-e stands for low emissivity. This glass is an energy efficient way to control the heat being allowed in and out of a home or environment. Low E-glass might be placed between two panes of glass. Solarban Glass (formerly Solarban 70XL Glass ) has a transparent, color-neutral aesthetic and is the most commonly specified triple-silver-coated low-e glass in the industry. Specially designed coatings may be applied to one or more surfaces of insulated glass.

One type of coating (low-e coatings) reduces the emission of radiant infrared energy , thus tending to keep heat on the side of the glass where it originated , while letting visible light pass. This in glazing with better control of energy - heat originating from indoors in winter remains inside (the warm side), while heat during summer does not emit from the exterior, keeping it cooler inside. Long wave infrared is the heat produced by our bodies, heaters and the furnishings in a warm room. The transmission of long wave infrared is significantly reduced by the low-e coating. A low-e glass window (which stands for low emissivity) is simply a windowpane coated in microscopic layers of metallic oxides.

It reduces heat gain or loss by reflecting long-wave infrared energy (heat) and therefore, decreases the U-value and solar heat gain, and in doing so, improves the energy efficiency of the glazing. Low-E glass refers to glass with a low -emissivity coating. The U- value of Low E 1glass is 0. Low E 2(Mass production only) Low E 2glass delivers year round comfort in all climate conditions. During the winter, the Low E 2glass has the ability to reflect heat back into the room.

Comparing low -Eand low -Ewindows begins by comparing how much light is transmitted through the glass. Typically, the more layers of low-E coating applied to a window, the. Low - e coatings provide various performance levels and the glass can be used in a variety of ways including single glazing , laminated glass or double glazed windows.

The benefits of low - e glass Low - e glass can reduce the amount of heat that is conducted through the glass by around compared to ordinary glass. The “e” in low-e stands for emissivity. The low emissivity coating (low-e) means that less heat passes through the glass than would usually be the case (compared to standard float glass).

Double-glazing is also known as an IGU, an insulated glazing unit. High-solar-gain low - E glass products are best suited for buildings located in heating-dominated climates and are the product of choice for passive solar design projects. A low - e glass window (which stands for low emissivity) is simply a windowpane coated in microscopic layers of metallic oxides. Double glazing windows, on the other han do a great job of keeping heat inside the building, and they allow heat gain during winter through the glass.

As a general rule of thumb, double-glazing windows let more daylight.
