Jinan glass film, Jinan insulation film glass insulation film for improving the energy efficiency of application security glass can be traced back to the common law in 1960. The original intention was to develop the film, when in order to control the load caused by solar heating, refrigeration is not balanced, the earlier film has only reflect solar radiation the windows to prevent heat glass surface is increased performance. With the continuous development of the manufacturing process, body-tinted window film a new generation was born, its rich color for architects to provide a broad design space. The main colors: brown, gray, gold, amber, blue, green and so on. 1970 US energy crisis leads to another aspect of performance development membranes reduce indoor heat loss (the "insulation.") Found that not only can be used as a transparent polyester film medium, a more long-wave infrared radiation absorption and inverse capacity . After repeated tests. Membrane materials, structures with a big change, but also improve the film "insulation" will produce a "low-E film" LOWE film architectural glass insulation film is composed of the most basic: polyester substrate (PET), one side coated with anti-scratch layer (SR), the other side is installed and the protective film layer. When construction of the installation, the protective film thrown off, exposing the layer affixed to the side of the glass inner surface (if it is specially designed for the film posted outside, then affixed to the outer surface of the glass) PET is a durable and strong, rugged, high toughness, resistant to moisture, resistant to high and low temperature resistance are good material. It is crystal clear that a variety of techniques for mass dyeing process, the metallization layer, magnetron sputtering, dissection of become films having different physical properties to adapt to different commercial buildings, residential, shop windows, bank counters, car or ship, etc. place needs. Architectural glass film is divided into two series: building energy-saving films and security films. The main varieties are: mass-colored film, heat-reflective insulation film, low reflective insulation film, high transmittance magnetron sputtering film, low emissivity (LOW-E) film, museums and archives dedicated film, matte and translucent decorative film, transparent safety film. Four basic characteristics: energy-saving insulation, UV resistant, beautiful and comfortable, safe and explosion-proof. Glass film in the construction industry may be referred to: "amphibious" products, which made both for the renovation of old buildings, it can also be used for new building
