  • 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…

  • Laminated Glass-Single piece thickness

    Most laminated glass are made with 2 piece same thickness single pieces. Such as 21.52 PVB laminated glass,17.52mm laminated glass,12.76mm laminated glass,20.89mm SGP laminated glass,why the laminated glass shall be made with equal thickness single pieces? 1.Glass flatness.As we know that after tempering process,glass will has overall bow and local bow.thin glass,especially 3mm and 4mm will have larger overall bow,while thicker ones flatness is much better. If we laminate 4mm glass with 6mm glass,the glass flatness difference will cause imbalance…

  • 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…

  • Why we choose system windows and doors.

    Most people pay attention to the quality of obvious parts such as aluminum profile, glass, accessories, etc when buying high-quality doors and windows,, but do not understand the professional performance requirements of doors and windows, more concerned about product quality, cost-effective and other factors. In the initial consumption ideology, high-quality doors and windows are considered to be equal to high-performance doors and windows. High quality doors and windows = high quality profiles + glass + accessories strips + processing technology…

  • 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…

  • Advantage of PVDF aluminium veneer plate

    The PVDF coated aluminum veneer is made of high-quality aluminum alloy panel, and the advanced CNC bending technology ensures that the sheet is flat and not deformed after processing, and the external force resistance is superior in the installation process of the aluminum veneer. PVDF coated aluminum veneers are used in exterior curtain wall. Features of PVDF coated aluminum veneer: 1. Light weight, good rigidity and high strength. The 3.0mm thick aluminum plate weighs 8kg per square and tensile strength…

  • 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…

  • Difference between Single silver low-E,double silver low e and triple silver low e

    Difference between Single silver low-E,double silver low e and triple silver low e Soft coated low e glass is widely used in modern glass curtain wall.But many designers and owners doesn’t know clearly the difference between single silver low e ,double silver low e and triple silver low e. Here we introduce several main difference to help you identify the different low e coating. 1.LSG. LSG is the ratio between the glass light transmittance and SHGC. Double silver low e…

  • The sun room types and classification

    The sun room(or glass conservatory) can be built on the terrace of the duplex building, the private garden,the top floor of the building, private villas and other places. Its building facade even includes the top are glass structures. Because the room require light and ventilated,as well as good sealing effect,the sun room facade and the top are mostly composed of openable doors and windows. The quality of the door and window determines the success of the sun room construction. When…
