Glass film is divided into three categories according to its function and application range: building energy-saving film, safety explosion-proof film and interior decoration film. Building energy-saving membranes, as the name suggests, are used in residential, office buildings, commercial buildings and other building doors and windows, curtain wall glass, through solar control, improve the indoor environment, reduce the energy consumption of refrigeration and heating, thus achieving energy-saving glass membrane.
It is widely used in homes, offices, leisure and other places. In the summer, the glass film with different performance indicators--the energy-saving film can greatly reduce the cooling cost of the air conditioner by blocking the solar heat energy of up to 50%-79%. In winter, the indoor heat is lost through the window, which not only makes the indoor staff feel uncomfortable. And it adds unnecessary energy costs. The installation of the glass energy-saving film on the inner surface of the ordinary glass can reduce the heat loss by 30%, thereby achieving the effect of warming the room indoors in winter.
Glass film development
The application of glass film to improve the safety and energy saving of ordinary glass can be traced back to 1960. At the time, the original intention of the film was developed. In order to control the imbalance of heating and cooling caused by the solar load, the early film only had the property of reflecting the solar radiation out of the glass window to prevent the heat increase on the inner surface of the glass.
With the continuous development of the manufacturing process, a new generation of body-colored insulating film has been born, and its rich color provides architects with a broad design space. The main colors are: brown, gray, gold, amber, blue, green, etc. In 1970, the US energy crisis led to the development of another aspect of the membrane to reduce the loss of indoor heat energy (ie, "insulation".) The study found that polyester film can not only be used as a transparent medium, but also has the ability to absorb and counter-radiate long-wave infrared. . After trial and error. The material and structure of the membrane have been greatly changed, and the "insulation" of the membrane has been enhanced to produce a "low-emission membrane" LOWE membrane.
The most basic structure of the film is a polyester substrate (PET), which is coated with a scratch-resistant layer (SR) on one side and a glue layer and a protective film on the other side. During installation, the protection film is removed, and the exposed layer is attached to the inner surface of the glass (if it is specially designed for external film, it is attached to the outer surface of the glass). PET is durable, strong and high. A material that is excellent in toughness, moisture resistance, high resistance, and low temperature. It is clear and transparent, and it is processed by various processes such as bulk dyeing, metallization plating, magnetron sputtering, and sandwich synthesis to become films with different physical properties, which are suitable for commercial buildings, houses, shop windows, bank counters, cars or ships. The needs of the venue.
Glass film for construction is mainly divided into two series: building energy-saving film and safety film. The main varieties are: bulk dye film, heat reflective film, low reflection film, high light transmission magnetron sputtering film, low radiation (LOW-E) film, museum and archive special film, matte and translucent decoration Membrane, transparent safety film, etc. Four basic characteristics: heat insulation, energy saving, UV resistance, beautiful and comfortable, safe and explosion-proof. Glass film can be called “amphibious” products in the construction industry, and it can be used for both old building renovations and new buildings.www.snpefilm.com
