• 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 calculate the glass STC?

    One of the features of glass is sound proof,whether it’s single glazing, laminated glass,insulated glass or even laminated insulated,the glass can reduce the sounds transferrd from outdoor to indoor. The order of sound insulation performance from poor to excellent is: monolithic glass < laminated glass <double insulated glass < triple insulating glass< laminated insulated glass. Here we introduce a simple formula to calculate the glass STC-sound transmission class. 1.Monolithic glass Formula: R=13.5lgM+13 R:Monolithic glass STC M:Glass density Example:6mm clear tempered…

  • Fireproof glass types and classification

    Fireproof glass is now widely used in the construction and household industries. Such as: architectural windows and doors,partition walls, skylights, smoke blocking wall, perspective floor,exterior walls, outdoor,windows,fire-proof glass frameless door; building patio, atrium,etc. Compared with traditional architectural glass,fireproof glass(or fire rated glass) is relatively new,some glass processors are not really understand the fireproof glass very well,fire-rated glass manufacturers usually named their fire resistant glass with unique code and don’t leak detailed glass configuration to clients,This complexity of fire glass products…

  • What’s Dupont SGP Interlayer?

    SGP is also called SentryGlas Plus,which is one kind of high performance laminated materials developed by Dupont,Kuarary acquired Dupont in the end of 2014. SGP has very high strength,SGP laminated glass bearing capability is 2 times that of PVB laminated glass,but the bending deflection of SGP laminated is only 1/4 of PVB laminated glass under the same thickness and load condition. The tearing strength of SGP interlayer is 5 times higher than PVB film,even if the glass breaks,the SGP can…

  • Ultra clear PVB for ultra clear laminated glass

    Ultra clear glass,or low iron glass has higher transmittance compared with normal clear glass. It offers elegant crystal like appearance ,but when it was made into low iron PVB laminated glass,the PVB will usually become yellow color and affect the overall light transmittance and appearance especially when 4 or more layer PVB used. To solve this problem,ultra clear PVB was invented to meet the high transmittance -ultra clear requirement. Trosifol launched ultra clear PVB,as we can see in the picture,7.6mm(10 layers…

  • How to decrease glass purchasing costs through controlling glass size

    As we know,the float glass manufacturers have limited standard float glass size options. In most cases,glass processors buy standard glass panels and then cut,edging works,tempering,laminating,insulating process etc. If your projects require 10mm 1500*1500mm tempered glass,there’ll be no suitable standard float glass sheets that can achieve high cutting ratio,you may have to cut from 2140*3050mm,in this case ,glass waste reach 30%,the costs can be USD2.5/SQM higher than 2100*1500mm. So glass waste ratio is a very important costs of the glass total…

  • How to confirm the best PVB thickness for your project?

    Laminated glass is widely used in buildings,but confirming the best PVB thickness for your project to save the most costs and guarantee the glass quality is quite important. PVB thickness are usually 0.38mm,0.76mm,1.14mm,1.52mm,2.28mm.Here is a guideline -PVB interlayer thickness for different laminated glass-Annealed laminated glass,tempered laminated glass,heat strengthened laminated glass,curved laminated glass. Bulletproof glass,aquarium glass,and multi layer laminated glass are excluded. 1.Annealed laminated glass Glass Types Glass thickness PVB thickness L≤800mm L>800mm Annealed laminated glass ≤6mm 0.38 0.38 8mm 0.38…

  • Specification of SGP interlayer

    SGP laminated glass is widely used in structural glazing,hurricane proof windows and doors,it offers extremely high strengthen and keep glass integrity,more designers and architects select SentryGlas Plus(SGP) laminated glass .As SGP laminated glass price is high,to take the most advantage of your costs and glass,,please pay attention to this during your design ,here is some introduction of SGP specification. 0.89MM SGP interlayer -Packed in rolls, 200M/Roll Normal Width :1220mm,1530mm,1830mm. Other width:2250MM,2400MM,2500MM,2700mm   0.76mm SGP interlayer -Packed in rolls, 200M/Roll Normal…

  • Difference between PVB,EVA ,SGP interlayer

    Laminated glass is also known as safety glass. As the name suggests, laminated glass is composed of multiple layers of glass. Except for the glass, the interlayer in the middle of the glass. Usually there are three kinds of interlayers: EVA, PVB, SGP. PVB PVB is a widely used sandwich material for architectural glass and automotive glass. The storage process and processing method of PVB interlayer is more complicated than EVA, and the requirements for temperature and humidity are high….

  • PVB Laminated glass VS SGP laminated glass

    Laminated glass was generally made of PVB film; since PVB film was originally developed for automotive glass rather than for the building curtain wall industry, it has been used for many years in the construction industry, has a wide range of uses and achieved good safety results. However, due to the flexibility, softness and small shear modulus of PVB film, the two glasses will have relative slip, load capacity and bending deformation after being stressed,it is prone to yellowing, so…
