• How the glass U value been affected by the installation angle?

    In most projects,glass is installed vertically.With high performance silver low-E coating,the insulated glass on the vertical facade will decrease the solar energy transmitted the glass,and save air conditioner heating and cooling fees. While many architects have designed many unique facades,the facade is not 90° vertically,but with some slopes,and glass is also used in skylight to get more light transmittance.But will the insulated glass thermal insulation performance change in this situation? Here is the result we calculated with Berkery LBNL window…

  • 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…

  • 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…

  • 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…

  • All glass curtain wall glass types

    All glass curtain wall , means the surface panels and fin are all glass.Glass itself is not noly the surface decoration panels,but also structural parts of the facade. All glass curtain wall height is similar as the floor height,and use tempered glass or laminated glass,thickness between 10-19mm.If glass height over 4 meters,it’s necessary to add glass fin thickness over 12mm. Classification of full glass curtain wall:suspending curtain wall and free stand type curtain wall,rib point glass curtain wall. All glass…

  • How to select spider fittings in Point supported glass curtain wall?

    Pointed supported glass curtain wall refers to a new type of modular building structure in which the building glass and the metal (or glass) supporting structure are connected by metal connecting members and fasteners, which is also called a point frameless glass curtain wall. The main components of a building point glass curtain wall 1. Support system It is the main force component,Such as: glass ribs, stainless steel column, aluminum profile column or anti-corrosion, fire-resistant steel structures and stainless steel…

  • Is solar control PVB film really effective in laminated glass?

    Solar control PVB film is used to reduce the solar energy that transmitted the laminated glass.Same as normal PVB film ,solar control PVB film specifications, laminating workmanship is exactly same as normal PVB film. Solutia SG41/SH41 are solar control film produced by Eastman,L-SEC SCF301 and SCF 307 are products of Sekisui. Here we study the film and see if these solar control film is really effective when been applied in laminated glass. Firstly let’s see why Solutia develop solar control…

  • How float glass is produced?-MORN BM

    The float glass process is also known as the Pilkington process, named after the British glass manufacturer Pilkington, which pioneered the technique (invented by Sir Alastair Pilkington) in the 1950s at their production site in St Helens, Merseyside. Float glass,mostly are soda-lime glass, is made by floating molten glass on a bed of molten metal- tin, This method gives the sheet uniform thickness and very flat surfaces.Which makes it easy to be further processed-heat treated glass(tempered glass,heat soaked glass,heat strengthened…

  • PVB/SGP interlayer shear modulus

    If two sheets of glass, lying on top of one another, are placed under load, they will start to bend (distort) independently. Dis-placement occurs between the two inner surfaces, which are in direct contact with each other. This is because one of the two surfaces is being stretched while the other is being compressed. If both sheets are laminated with an adhesive polymer interlayer,this must be able to internally compensatefor the distortional differences (i.e. absorbshear forces). For designers of architectural…
