Advantages of glass film
Glass film has become quite popular abroad, but in China, the utilization rate of buildings is still very low. As a new type of energy-saving decoration building materials, glass film has seven advantages:
1. Insulation and heat preservation;
2. Safety explosion-proof;
3. UV protection;
4. Anti-glare glare;
5. Easily create a private space;
6. Enhance the visual effect;
7. High temperature resistance and fire resistance.
These seven advantages are very useful in people's daily life. It is precisely because of these advantages that it has been favored and praised by more and more people, and is widely used in people's lives.
Glass film price
Depending on the brand, quality, and type, the price ranges from tens to more than 1,000 square meters.
The film belongs to an emerging market in China, and the quality is also uneven. It is best to shop around.
If the price is below 100, there is basically no need to consider it, and the quality cannot be praised.
The mainstream price is generally between 150-300. It is best to choose a brand that has foreign manufacturers and original warranty.
1. Touch by hand
High-quality films are thick and smooth to the touch, while inferior films are soft and thin, lack sufficient toughness, and are easy to wrinkling.
2. Smell
Inferior films usually use pressure-sensitive adhesives, which contain a large amount of benzaldehyde molecules, which will volatilize and produce peculiar smells under sunlight, while special automotive film installation adhesives have almost no taste.
3. Seeing
High-quality explosion-proof film has high clarity and good see-through performance regardless of color depth, while inferior film has uneven color.
4. Quality Assurance Card
Only the film with the manufacturer's warranty card is reliable. The manufacturer's warranty card usually contains the warranty items, years, payment methods, and the real manufacturer's name, address and telephone number.
5. Wipe with chemical reagents such as alcohol, gasoline, asphalt cleaner, etc.
Because the inferior film is only dyed by the adhesive layer, or only the adhesive layer is coated with UV blocking agent, after removing the protective layer of the film and wiping the adhesive layer, the fading phenomenon can be seen, or by instrument testing, it can be found that the ultraviolet rays are greatly reduced.
6. Technical parameters
Visible light transmittance, heat insulation rate, and ultraviolet blocking rate are professional terms commonly used by manufacturers to reflect the performance of films. The relationship between the three is usually: the more transparent the film, the lower the heat insulation; the more reflective film, the heat insulation higher. Consumers can measure with storefront instruments to see if they are close to the nominal technical parameters.
7. Anti-scratch
When the high-quality film is used to lift the car window normally, the surface of the film will not be scratched and fogged, while the inferior car film has obvious defects in this regard.
8. Check the packaging and product information
Whether the outer packaging and information of the products sold have the original manufacturer's detailed product model, address, telephone, website, and barcode. In addition, it depends on whether the unified publicity logo of the original factory is used, and only authorized dealers can use all the publicity logos of the original factory, otherwise they will be investigated for infringement responsibility; it also depends on whether there is a valid authorized distribution certificate.
