• What’s the thermal conductivity measurement unit?

    When evaluating the thermal insulation performance of a glass product,we usually know that clear& tinted single piece glass is 5.84,Single silver low-E insulated glass 1.8,and double silver low-E is 1.55-1.65.The lower the value,the better thermal insulation performance the glass has. But What does the value mean and the measurement unit? Actually the measurement unit is W/M2.k,which means watt/square meter/Kelvin,it’s under same confirmed air condition,the heat transfered throught the glass products. While even this measurement unit,there’re many different conditions depend on…

  • 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…

  • How laminated glass is made?

    Laminated glass is widely used in glass facade,blustrade,glass fencing,canopy,glass skylight ,etc.As safety glass,laminated glass is made with 2 lites single piece glass and interlayer(PVB or SGP interlayer). The interlayer can bond 2 piece glass together and keeps glass integrity once broken,it offers high security and avoid hurts. Laminated glass is usually produced with glass laminating line,then how the glass and PVB interlayer bonded together? Laminating line consist of glass loading table,glass transmission conveyor,washing and drying machine,glass positioning machine,waliking suction hanger,PVB…

  • Why we use triple silver low-E on your facade?

    Currently single silver low-E cannot meet the architectural energy saving requirement,the new double silver low-E and triple silver low-E ,in addition to the argon filled glass,triple glazing has decreased the glass U value significantly,especially the passive glass,through argon filled triple glazing with two pieces double silver low-E,the glass Uvalue has decreased to 0.6W/m2.k.Triple silver low-E has been more and more popular,then why shall we use triple silver low-e in your facade? The advantages of triple silver low-E: 1.Triple silver LOW-e…

  • Digitally printed glass VS UV printed glass

    Silk screen glass is an traditional glass that used as glass spandrel ,and decorative glass with different colors,but the for technics limitation,the color types on one piece silk screen glass is only 2-3,it cannot show complex patterns on glass surface. Digitally printed glass is from Israel company -DipTech,their machine allow glass processors print whatever patterns they want on glass surface,especially pictures with multi complex colors.As alternative of silk screen glass that can be used on exterior decoration works,more and more…

  • Why heat soaking process is not recommended ?

    The Nis inside glass will cause tempered glass self explosion after installation.The glass breakage,replacement will bring numerous problems to clients,so many glass processors recommend heat soaking process after tempering to decrease the self breakage ratio. Heat soaking process is finished by heat soaking furnace,take the glass into the furnace,heating up to 300℃,keeping the temperature for 2 hours and then decrease temperature,the Nis inside glass will transfer and expand many times which can cause glass breakage,after heat soaking,the glass breakage ratio…

  • How to make the glass frosted glass?

    Frosted glass is widely used in shower rooms,washrooms,glass partition that require privacy.The feature of frosted glass is ,light can transmitted through the glass but cannot see clearly through the glass.There’re several methods to make the glass frosted with patterns. 1.Sandblasted glass Sandblasted is a physics method.Through spraying emery with high pressure,the emery will remove the glass surface and make glass opaque. This method costs is low,but as the emery diameter is big,the sandblasted glass surface is very rough,can be only…

  • How glass size affect the glass price?

    Many clients have a concept of general price of normal glass,such as 6-12-6 insulated glass,13.52 laminated glass,while in many cases,same glass combination has quite different price,there’re many reasons causing this situation,such as order quantity,glass size,glass shape,holes&notches on glass,processing difficulty,let’s analysis how glass size affect the glass price. 1.Glass size too big. Glass factories quotation is usually based on sizes below 2440*3660mm,if glass size too big,especially for some over sized glass,point supported glass is usually over 4000mm,in that case,processors has to…

  • What’s the function of argon gas in argon filled insulated glass?

    Argon is a kind of inert gas, which has colorless, odorless, non-toxic properties and stability. In air, its content is about 1%, and is the most economical inert gas compared with helium and neon. Argon is usually been filled in the insulated glass to increase the glass thermal insulation performance,let’s take example of single silver low-E + Clear insulated glass, argon content increase from 0-100%,the glass U value decrease from 1.86 to 1.59,for triple silver low-E glass, U value decrease…

  • Low-E coated tinted glass IGU price

    80% low-E coatings are on clear glass,but in some hot areas,especially Africa,South Africa areas,the high temperature force clients to coat low-E coatings on tinted glass, such as euro grey,crystal grey,ford blue ,etc to decrease the glass Solar shading coefficient and light transmittance. Compared with normal insulated glass,low-E coated tinted glass is higher and sometimes varies much,the costs causing the price difference is as below: 1.Raw materials:tinted glass price is higher than normal clear glass,around USD0.5-1/SQM. For normal clear glass, glass…
