Professional guidance on the selection of architectural window film

The glass window film products on the market are mixed. If you want to select the appropriate performance of the building window film, you need to distinguish the products from the following aspects: Energy-saving performance: One of the main functions of the building window film is to save energy and reduce emissions, so the selected building window film must be It must have a high solar barrier rate, and other glass films do not necessarily have high thermal insulation performance according to the purpose (such as decoration, safety, beauty, etc.). The main indicator of energy-saving performance is the shielding coefficient, which has better energy-saving effects. The shielding coefficient of architectural window film is mostly around 0.5; UV blocking: architectural window film generally requires a higher service life, so its structural design usually uses UV blocking PET film on the basis of adding ultraviolet absorber to the glue layer. The index of UV blocking is often calibrated by UV transmittance, and the UV transmittance of architectural film is required to be less than 1%; shelf life: architectural window film has a longer use time, compared with commonly used automobile film and decorative film, its color retention performance , Glue durability and other aspects are more stringent. The shelf life is generally more than three years, and the shelf life of better architectural window films will exceed five years.

The national standard for functional film for architectural glass was promulgated and implemented in 2012 (GB/T29061-2012), which provided customers with quality technical parameters for the selection of architectural film. Changzhou Shanyoudishan Protective Material Manufacturing Co., Ltd. participated in the Standard drafting work, and the design of architectural window film products in accordance with the national standard requirements of architectural window film, and many products have passed the inspection and certification of the national quality inspection department. After the product is attached to the glass surface, it has the effect of energy saving and heat insulation. At the same time, it also has the characteristics of beautiful appearance, explosion-proof and anti-theft, prevention of scratches, and reduction of glare.

Heat insulation effect: It can be seen from the picture that after filming (the lower temperature side), it has selective barrier properties to the infrared light zone, which can effectively reflect and absorb solar heat, block heat insulation, reduce infrared penetration, and make the film glass green Energy saving effect.

Home decoration effect: reduce dazzling glare, create a harmonious and comfortable indoor space environment; prevent light pollution, protect the environment and eyesight; UV transmittance is less than 1%, which can effectively shield UV rays and protect furniture from fading.
