Specifications
Low-e insulating glass definition and ordinary single-layer glass, ordinary insulating glass's comparison of energy saving:
Low-e insulating glass is the first choice for national green building energy saving energy saving building materials, its energy saving features satisfy even far beyond the state public buildings and residential building energy-saving mandatory requirements of the material.It using the method of vacuum magnetron sputtering coating, on the surface of ordinary architectural glass coating on metallic silver and its auxiliary membrane after layer it with another piece of glass set by a variety of technology into the middle of dry air insulating glass products.Low-e hollow products compared with the ordinary energy-saving glass, can take advantage of the high reflection characteristics of thermal radiation, at the same time, assure indoor natural lighting in the summer heat of the sun block outside, more and more to prevent indoor heating in the winter by glass erosion to outdoor, which have the significant effect of building energy efficiency. Compared with the ordinary single-layer glass, energy-saving glass (low-e insulating glass), heat insulation, heat preservation effect is remarkable, energy saving 67-70%, compared with the ordinary insulating glass saving energy about 40%
(Please see the table below).
Low-e coated glass is also called low-e glass, low-e glass is the glass surface silver plated Low radiation material and metal oxide film, glass brings out the different colors.Its main function is to reduce glass U value, selectively reduce the Sc at the same time, comprehensively improve energy-saving features of the glass.Remarkable features as follows: high infrared reflectivity, can directly reflect infrared heat radiation;Surface emissivity of E is low, the ability to absorb foreign energy is small, thus the heat energy to radiate less;Shading coefficient of Sc is wide, according to the need to control the through the amount of solar energy, to adapt to the needs of different regions.
According to the layer structure contains silver layer is different and can be divided into: single silver, double silver, three silver low-e products, in some instances, you need a high, LOW and need to shading coefficient of low-e products, so the double silver also arises at the historic moment, in general, the same shading coefficient, double silver low-e can have higher through visible light.Three silver this feature is more obvious.Double silver glass can be used in almost any situation, it has the following several characteristics: with a lower than shade type low-e glass shading coefficient;With low emissivity have heat preservation effect;Generally have low reflectivity, permeability is good.
Quality Standard
In line with the GB/T18915.2-2002 coated glass national standards.
Noun explanation
Visible light transmittance: In the visible spectrum (380 nm to 780 nm) within the scope of the percentage of the intensity of light through the glass.
Visible light reflectivity: in the visible spectrum (380 nm to 780 nm range), the percentage of the glass reflected light intensity.
Solar transmittance: in the solar spectrum (300 nm to 2500 nm) within the scope of ultraviolet, visible and near infrared.The percentage of the light energy through the glass.
Solar reflection: in the solar spectrum (300 nm to 2500 nm) within the scope of ultraviolet, visible and near infrared
The percentage of light energy by glass reflection.
U value: ASHRAE standard conditions, because of the heat transfer of glass and indoor and outdoor temperature difference, formed by air to air heat transfer.Its English unit is: the British thermal unit per hour per square foot per Fahrenheit.Metric unit is: watts per square metre per degree centigrade.U value is lower, the lower the heat transfer through glass also.U value reflect is: due to convection conduction transfer of heat through the glass, including glass absorbs heat radiated outward again after delivery.Therefore, low emissivity E value of the glass, U value is correspondingly low.
