• The advantage of diffused glass in Greenhouse

    Glass has been used as primary glazing materials for greenhouse for long times because of its high light transmittance and longevity.Compared with other glazing materials, glass has high price and has poor thermal insulation properties.Although glass high daylight transmits , most of that light penetrates through the glazing directly;only little are diffused light. Therefore, glass-glazed greenhouse has better lighting than most other glazing choices, on sunny days the uniformity of that light is poor since the structure and overhead obstructions (heat pipes, hanging baskets, etc.) solid distinct shadows on crops below. Diffused glass is usually low iron patterned glass that scattering the sunshine. A challenge is to prevent dust from accumulating without scratching…

  • 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…

  • 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 iron glass VS clear glass

    Float glass refers to the glass produced by the floating method. The general principle is to pour the molten glass into the surface of the liquid (liquid tin) with a specific gravity greater than that of the glass liquid to form the glass. The low iron glass(or ultra clear glass) is relative to normal clear glass. The color of pure glass should be colorless and transparent like white crystal (the main components of both are silica), due to impurities in…

  • 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…

  • Safety Glass

    Safety glass can be divided into two categories: tempered glass and laminated glass. Tempered glass is made by passing the ordinary glass through a heat treatment process to increase its strength by 3-5 times, and can withstand an external impact or temperature difference of a certain energy without breaking, even if it is broken, the whole piece of glass is broken into  small particles&fragments. It will not cause injury, so it has certain security. Tempered glass can not be cut,…

  • THE BENEFIT OF DOUBLE GLAZED UNITS FOR CURTAIN WALL

    Top building glass curtain wall is generally with insulated glass(double glazed units), glass is the most thin, easy to heat transfer in building external wall material.double glazed units with aluminum frame of desiccant through the gap above the aluminum frame that makes the air inside the insulated glass stay dry for a long time, with the excellent insulating performance. High sound insulation: double glazed units can decline of 27-40 decibel noise, 80 decibel traffic noise outside the room, then only…

  • 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….
