• What’s the difference between double glazing and triple glazing?

    Most glass used in facade is double glazed units, which is made of 1 piece low-E coated glass and 1 piece clear glass,the most common glass combination is 6 low-E+12A+6 clear glass. If the low-E coating is double silver low e coated,glass U value is around 1.6W/m2.k,for triple silver low-E the U value is same but will with lower Solar coefficient.Evne if we change the 2nd glass to double silver low-E,the U value won’t change much. With the development of…

  • Low e coating on tinted glass-advantage&disadvantage

    Normal low e coating are coated on normal clear float glass,or low iron float glass,while many facade designers prefer low e coating on tinted glass for below reason: a.Low glass  reflective ratio:tinted glass such as euro grey glass,French green glass ,euro bronze glass reflective ratio is about 6%-8%,once coated with low e coating,the double glazed units reflective ratio will be below 10%.     b.Low solar coefficient.For some hot areas,such as southeast Asian countries,the project require both low U value,and…

  • Spider Glass Curtain Walls-Glass options

    Spider Glass Curtain Walls,or point supported glass curtain wall offer great transparency . it is a system for point-supported vertical glazing in which thermally toughened (tempered) glass or,laminated safety glass are used, in single glazing or in double glazed units. Laminated safety glass (tempered laminated glass) is preferable to be used in single glazing or as the outer sheet of the insulating glass units. The rectangular glass sheets have 4 or 6 countersunk drilled holes into which countersunk stainless steel bolts acting aspoint-fixings. The space between…

  • Glass Classification

    Tempered glass. It is processed by ordinary clear float glass. Tempered glass has two major characteristics compared to clear float glass: 1) The strength is several times that of clear float glass, the tensile strength is three times that of the latter, and the impact resistance is more than five times that of the float glass. 2) Tempered glass is not easy to be broken, even if it is broken, it will be broken in the form of particles without sharp angles,…

  • Thermal insulation function of low e coating

    In the mid-1970s, it was discovered that most of the heat transfer of double glazing was caused by infrared radiation exchange from one layer of glass to another. Therefore, as long as the emissivity of any one of the double glazing is reduced, the heat transfer can be greatly reduced. This is the reason for LOW-E glass. There is data showing that the clear float glass has an emissivity of 0.84 and the low e coated glass with an emissivity of 0.2 reduces the…

  • Hard coated low e VS Soft coated low e

    Low-E glass, short for Low Emissivity Glass,It is a coating on glass surface. This glass not only has high visible light transmittance, but also has a strong ability to block infrared rays. It can play the dual functions of natural lighting and heat insulation. Low-E glass is divided into offline Low-E glass(soft coated low e) and online Low-E glass(hard coated low e) according to the manufacturing process. On-line Low-E glass is a functional film with low radiation performance on the surface of the glass…

  • Low e glass introduction

    Low-emissvity glass (also known as LOW-E glass) is a multi-layer metal or metal oxide film coated on a glass surface, one or two layers of which are mainly Ag-based. It can effectively reduce solar energy absorption or control energy loss, and greatly reduce the heat transfer coefficient of glass. It can reflect 50%~80% of the heat transferred by glass, especially far-infrared radiant heat, while allowing all or part of visible light to pass. Coated glass. Insulated glass(double glazed units) processed…

  • Low-E Coated Glass

    Low-e coated glass were developed to minimize the ultraviolet and infrared light that can pass through glass without compromising the amount of visible light transmittance.  The biggest advantage of low-e coated glass is low U value,double glazed units(insulated glass) with high performance low e coating can decrease the heat pass through the glass and air conditioning fees.Energy efficient glass is becoming more and more popular,especially modern glass curtain wall and high rise glass projects. Morn supply different low-e coated glasses:…
