• Advantage of vacuum glass

    Vacuum glass as a new generation of energy-efficient glass, vacuum glass has heat transfer performance advantages,the glass takes advantage of the low thermal conductivity of air. In terms of heat transfer,the thermal conductivity of the air or filled argon has small thermal conductivity. Insulated glass dominates gas heat transfer, so that the effect of improving LOW-E glass performance to reduce radiant heat is not obvious. Insulated glass made of the best LOW-E glass (such as emissivity ≤ 0.1) is filled…

  • 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,…

  • The history of glass

    The glass is originally obtained by solidification of acidic rocks ejected from volcanoes. Around 3,700 BC, the ancient Egyptians had made glass ornaments and simple glassware. At that time, only colored glass was produced. About 1000 BC, China made colorless glass. In the 12th century AD, commercial glass appeared and began to become an industrial material. In the 18th century, optical glass was produced to meet the needs of developing telescopes. In 1873, Belgium first produced flat glass. In 1906,…

  • 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…

  • 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…

  • 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…
