To choose the right glass film, first understand what glass film is and why it is necessary to apply glass film, and then know what kind of glass film to apply. Ordinary window glass cannot block light or insulate heat, while colored coated glass can block light but cannot insulate heat. A type of thin film that can both insulate and block light and transmit light (known as "glass film" or "thermal insulation explosion-proof film") has emerged as a new type of glass covering material and is widely welcomed by users.

Nowadays, glass film has become a must-have for glass modification. It has a fashionable and modern atmosphere. Building insulation film is a new type of window glass insulation material that replaces old-fashioned sun paper. It has good transparency and clarity, and no blind spots in the line of sight. Excellent properties such as high thermal insulation, energy saving, UV protection, and explosion prevention are not available in old-fashioned sun paper and curtains. Therefore, when selecting and using glass film, several performance indicators closely related to the quality of the film should not be ignored:

(A) The transparency and clarity of glass film;

This is an important performance of glass film that is related to indoor lighting for users. The sun paper and colored glass that were widely used in the past had deep colors and low transparency (usually below 20% or even lower). After the window and door glass are pasted, it becomes dark, affecting the transmission of indoor light and making the environment oppressive. Therefore, when choosing a product like this, if your beloved home has a lower floor and a closer distance, the effect can be imagined. However, glass film does not have such drawbacks.

Glass film has high transparency, regardless of the color depth of the film, the clarity is very high, and there will be no blurring phenomenon, which improves the brightness and comfort of the use environment. However, the light transmittance of different glass films varies. If the above phenomenon occurs, it is best to choose a glass film with a light transmittance of 40% or above. If the indoor light is already very dark on rainy days, choose a glass film with high light transmittance. If your home is on the second or first floor and the property is not very prosperous, with low passenger flow or several villa areas in the west, then consider installing explosion-proof film. The municipal government will require that anti-theft nets are not allowed to be installed in future building approvals, and the glass windows of your home are the last unsafe defense zone. See the introduction of explosion-proof film below.

(B) Thermal insulation rate is an important indicator reflecting the thermal insulation performance of glass film;

The common ordinary films on the market only have transparency without insulation, and some even have no indicators. After these films are installed on window glass, a large amount of infrared radiation heat still enters the room, making it very hot. However, true energy-saving insulation films have high reflectivity to infrared radiation, and a large amount of heat is reflected, so the indoor temperature is naturally much lower. Even if sunlight shines into the room, it will not cause a burning sensation. The intuitive method to test the insulation effect (insulation rate) can be found in the equipment of a hot baking lightbox tester with a data display screen.

(C) The performance of building explosion-proof film; This is also another important performance related to safety;

The material of general sun paper or inferior explosion-proof film is different from real explosion-proof film. Its film is very thin, soft to the touch, lacks sufficient toughness, is not resistant to ultraviolet radiation, and is prone to aging and brittleness. When it encounters accidental collision or external object impact, the film is easy to break and cannot stick the glass together. Explosion proof film is made of special polyester film as the substrate, which has strong toughness and is combined with special pressure-sensitive adhesive and metal layer. When the glass encounters accidental collision, it will be stuck together after breaking, and fragments will not splash everywhere.
