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 construction, remove the protective film, and expose one side of the adhesive layer to the inner surface of the glass (if it is specially designed for external film, it will be attached to the outer surface of the glass)
PET is a material that is durable, strong, tough, moisture-resistant, 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.
