• The advantages of insulated glass in curtain wall

    Superior energy-saving effect: Modern building energy consumption is mainly air conditioning and lighting. The former accounts for 55% of energy consumption, the latter accounts for 23% of energy consumption, and glass is the thinnest and most heat-transferable material in the exterior wall of buildings. Insulated glass creates a air barrier between the extrior and indoor and the temperature insulation performance is excellent. High soundproof performance: Insulated glass can reduce noise by 27-40 decibels, and 80 dB of traffic noise outside…

  • Factors that affect tempered glass flatness

    Factors that affect tempered glass flatness The heat treated glass is not as flat as float glass,the uneven ,both glass overall bow and local bow will cause visual distortion after glass was installed.If made into laminated glass,the overall thickness of laminated glass is different,the uneven will cause bubbles at glass edge or center and affect laminated glass quality.For insulated glass,the uneven PIB cause poor sealing quality,and somewhere will cause the installation. The reasons cause glass flatness problem is: 1.1 Heating…

  • Warm edge space insulated glass production

    Traditional insulated glass are made with glass,spacer,buytl sealant and structural sealant,the function of butyl sealant is to increase the watertight and airtight,the structural sealant is used to increase the structure strength of the insulated glass,especially for some facade IGU ,the size can reach 4000*1500mm,the glass need very high strength to keep the structure of insulated glass. Recent years,warm edge spacer,or super spacer insulated glass is more popular.The warm edge combine the advantage of butyl,desiccant,and secondary sealant together,the easy production process…

  • 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…

  • Low e coating position-Surface #2 VS Surface #3

    Most low e coatings for insulated glass are placed on surface #2,but some projects have the low e coating on surface #3,but what’s the difference if we place the coating on #2 and #3? Here we’ll introduce how the low e coating position affect the glass performance. Main difference: 1.Different SC value. Based on above data,SC value changed much based on different position.So clients should adjust the coating position according to the climate and SC requirement.In cold areas,the low e…

  • Silk screen /ceramic frit glass

    Silk-screening ceramic frit onto glass panels allows designers create unique appearance using patterns and color. Silk screening process is similar as heat treated glass(tempered or heat strengthened) but before heat treating process,ceramic frit inks is applied to the glass surface by silk screen and the tempering process will bond the inks to the glass permanently ,so different from back painted glass ,the patterns or colors will last lifetime and won’t fade or disappear during the glass lifetime. Ceramic frit glass…

  • Factors affect the facade materials costs

    What are the main factors affecting the cost of curtain wall materials? Today, I will tell you about it: First, glass 1.glass raw materials: clear glass (conventional), french green, low iron glass, etc. 2, the configuration of the glass: single piece, insulated glass,laminated insulated glass and so on. 3, glass coating: single silver Low-e, double silver Low-e, solar reflective glass 4, Secondary sealant: plastic brand (conventional domestic, imported Dow corning,Sika sealant), secondary sealant depth (structural sealant ≤ 12mm). 5, Insulated…

  • Advantages of thermal break aluminium windows

    Because the aluminum alloy is a metal, the heat conduction is relatively fast, so when the temperature difference between indoor and outdoor is large, the aluminum alloy can become a “bridge” for transferring heat. Door and window made by aluminium alloy has poor heat insulation performance .The thermal break aluminum is disconnected from the middle of the aluminum alloy. It uses nylon or PVC to connect the broken aluminum alloy. We know that the heat conduction of the nylon or PVC is obviously slower than…

  • The advantage of thermal break aluminium windows

    PVC doors and windows have been in the building door and window market for more than 20 years while the lifetime of excellent PVB windows and doors is only 10-20 years. Now many consumers will be replace PVC doors and windows with thermal break aluminum doors and windows. PVC windows and doors has 2 disadvantages: LIFETIME: PVC profiles is plastic and steel lining. If you don’t talk about inferior plastic steel, even high-quality PVC can’t solve the problem of brittleness…
