How should we choose glass insulation film?First of all, let's analyze the material from the first point. At present, the more mainstream window glass insulation film on the market is ceramic film and metal film. You can choose according to your specific needs.
The ceramic film is a heat-absorbing film, which will absorb a large amount of solar radiation heat, and this heat cannot be stored on the ceramic film, and will be transferred to the room again, and the position near the window will become extremely hot. In summer, the surface of the window glass covered with ceramic film is extremely hot. The ceramic film is similar to a transparent curtain, which can only play the role of sun protection. The thermal insulation effect is not obvious.
Metal film is also called anti-heat metal film, anti-heat cooling film, glass metal insulation film. An anti-infrared coating is added to the base material of the metal film. It mainly reflects the sun's infrared rays, blocks infrared radiation, and ultraviolet rays enter the room, thereby reducing the indoor temperature and achieving the effect of heat insulation and sun protection. Usually the metal film can be applied to cool the temperature by about 8-15 degrees.
Thermal insulation gives your home year-round protection. Reduce the overall increase in heat in your home. Reduced frequency of use of air conditioners improves comfort. Heat insulation film through 999% UV blocking, reducing fading damage to furniture, flooring. The most cost-effective energy-saving renovation has been carried out on the existing home windows, and the cost can be recovered through energy savings, effectively reducing the cost of home living.
Second, according to the needs of the home, the light transmittance and thermal insulation rate of the heat insulation film are also different.
If you live in a place that is not very hot in the south direction, you can choose a heat insulation film with a central thermal insulation rate and high light transmittance. At the same time, if there is a need for privacy and privacy, you can choose a one-way perspective privacy film, the principle of the privacy film is that the strong light side can not see the weak light surface, the outdoor can not see the indoor during the day, but the indoor can see the outdoor, which is very practical for the residents on the first floor facing the street or the low-rise residents who are too close to the building spacing.
If your home environment is in the western sun, it is very hot and humid in the summer. Then you can choose a heat insulation film with a light transmittance of about 30% and a thermal insulation rate of more than 90%. High shading, high heat insulation, to solve the problem of summer exposure to the sweltering heat.
Thirdly, from the perspective of the selection of heat insulation film brands, heat insulation films are divided into imported films and domestic films, imported films such as 3M, Dragon Film, Avery Dennison, domestic films such as Zhongfan, Zhongling, Kangdexin, etc., have been very excellent in technology, and have a long warranty of more than ten years. The substrate is wear-resistant and can withstand the needs of long-term use.
