How much does the heat insulation film play in winter?

In winter, the heat insulation film is mainly used to prevent ultraviolet rays, and the role of one-way perspective can also meet the privacy (so that the outside can not see the inside of the car clearly, and the inside of the car can clearly see the outside).

In most parts of the country, the weather in autumn and winter is mainly sunny, and ultraviolet intensity tends to be greater than in spring and summer. If the car is not affixed with car film, in the long run, the ultraviolet rays in the sun will be particularly harmful to the **.

It is understood that ultraviolet rays are divided into three types: long-wave, medium-wave and short-wave, of which long-wave has strong penetrating power, and regardless of the season, it is equally fierce all year round. It can penetrate under the dermal tissue, causing the collagen and elastin in the skin to be hit hard, resulting in sagging, wrinkles, microvasculature and other evil consequences. It will also dull and dull, and darken.

Dermal cells have poor self-protection ability, and a small amount of long waves can cause great damage, while more than 95% of the ultraviolet rays that are exposed to daily ** are long waves, so they are the most harmful to the skin.

In addition, the medium wave will oxidize the protective lipid layer of the epidermis, so that it will dry out and accelerate aging. Furthermore, the nucleic acids and proteins in the epidermal cells are denatured, resulting in acute dermatitis (i.e., sunburn) and other symptoms, and in severe cases, it is easy to lead to cancer. Although medium waves are easily blocked by clouds and other covers, and their penetration is worse than that of long waves, they have to be taken seriously in autumn and winter, when sunny weather is predominant.

At the same time, ultraviolet rays in sunlight are also the main cause of fading damage to the interior of your car, leather, fabric, etc.

Therefore, car maintenance experts remind car owners that in autumn and winter, film is also necessary. Not only that, but also to put a good film on the car in order to play its due role.

This shows that you don't know about membranes yet.

What is the role of the membrane?

Is it just insulation, no. It's not just insulating, it's summer. And insulation, winter.

Moreover, it can also play a role in isolating ultraviolet rays, protecting glass safety, single perspective, protecting personal privacy and many other characteristics. Our company posted it some time ago, and the heating has been in the past few days, and it felt very cold last year, and this year I even have to open the window. I asked the boss and said that when their family bought a new house this summer to decorate, it seemed to be called a master film or something.

It worked well in the summer, but I didn't expect it to work so well in the winter.

I have already discussed with my wife, and we will apply the film immediately after the new house comes down in two days.

The main function of the thermal insulation film containing the metal insulation layer is to block the heat in the near infrared, which is what we often call the heat in the sun, and the heat blocking effect on the far infrared part is low. Therefore, the general metal heat insulation film is not very good in winter, but has a good blocking effect on direct sunlight in summer.

Household heat insulation film also plays a very important role in safety. The laminated glass will not cause damage to people due to breakage.

At the same time, the metal heat insulation film has a good reflection, which can make people outside the house unable to see the situation in the house clearly during the day, and has the effect of protecting privacy.

In winter, the film is mainly insulation, so that the heating time in the sub-room will be reduced, saving electricity. My family just applied the film, and it is from the master film company. They are insulated in the summer, warm in the winter, and ultraviolet rays.

1. Is the heat insulation film useful?

In fact, the heat insulation film is very effective, it can effectively separate the indoor and outdoor temperatures, so as to ensure the indoor temperature. Heat insulation film is also known as safety explosion-proof film, it originated in 1966, with the passage of time and the progress of science and technology, the effect of heat insulation film is getting better and better.

2. Advantages of window insulation film.

1) Thermal insulation.

The main function of the heat insulation film is heat insulation, and it is also a metal reflective film. Since the electrons (free electrons) in the outer shell of the metal material are not bound by the nucleus, when irradiated by light waves, the electric field of the light waves causes the free electrons to absorb the energy of the light, and by reflecting infrared and ultraviolet rays, it can achieve the effect of effective heat insulation.

2) Privacy.

For owners who don't like to expose their privacy indoors, the effect of heat insulation film is very good. Generally, the interior can clearly see the outdoors after the film, while the outdoor cannot see everything indoors. The color of the one-way perspective heat insulation film is relatively rich and rich, and the range of choices is also relatively wide.

3) Explosion-proof.

When the window glass is broken by external force, its splashed fragments are very easy to hurt people, the substrate of the glass film is a tough PET polyester film, compounded with a special adhesive, attached to the inner surface of the window glass, forming an "invisible tough barrier" on the glass, preventing natural disasters and thieves and other damage, reducing personal injuries and rotting, protecting property, and replacing the home anti-theft iron fence.

1. Thermal insulation and energy saving: block heat radiation, ensure the good effect of indoor air conditioning and heating, and truly achieve indoor cold and hot air conditioning to the environmental protection temperature.

2. Sound insulation and shock absorption: reduce the sound transmission performance of glass doors and windows, shock absorption, sound insulation, create a good sound insulation effect, and enjoy a quiet and peaceful indoor environment.

3. Ultraviolet protection: effectively block more than 95% of ultraviolet rays, protect the human body, have more than 6 times the sunscreen ability of sunscreen, and prolong the service life of calligraphy and paintings, furniture, etc.

4. One-way fluoroscopy: improve the sense of belonging and security in private space, and ensure the safety of indoor personnel and property.

5. Explosion-proof and anti-corrosion: improve the tension resistance and adhesion of the glass, and maintain the whole after violent breakage, so as to avoid glass splashing and injuring people.

6. Shatterproof and shockproof: It can improve the high-strength tensile resistance of ordinary glass several times, improve the cushioning performance and anti-shattering of glass.

7. Beautiful decoration: rich colors, different colors, can be freely combined and matched, adding interior decoration style, comfortable and elegant.

8. Filter glare: create a light softening effect formed by high-quality sunglasses, protect the eyes and improve visual comfort.

In summer, the heat insulation film can block the sun, heat insulation and energy saving But the sunlight is not strong in winter, and it is not the main indoor heat preservation, the heat is diffused from the high temperature to the low temperature, some local cities will use heating in winter, the indoor temperature is higher than the outdoor, and the glass plus the heat insulation film is to add a layer of protective medium, which is also equivalent to better blocking the heat from spreading to the outdoors, which will play a role in heat preservation.

As for the better brands, just 3m dragon film, Bekaert, etc....

If you still don't understand, add this.

From the darker color film with a single function to the more and more diversified sunscreen and heat insulation film, there are still some ways to identify the authenticity of thousands of sun films on the film market. Whether there is a watermark, whether it is in a certain range, whether there is a warranty card, etc., are all ways to infer the true and false films.

To distinguish between real and fake explosion-proof film, first look at the color.

a) From the appearance, the color of the true explosion-proof film is uniform and soft, and there is no uneven color difference of wave depth. If the ordinary color film scrapes the pasted surface hard, the color will fall off, and the service life of the film is short.

b) The second is clarity. True explosion-proof film has high transparency regardless of color shade. The ordinary color film is darker because it adopts the ordinary dyeing process and relies on the color insulation, and there is always a foggy feeling when looking out from the car.

c) Finally, you can smell the membrane. Inferior film, after tearing the transparent adhesive layer, its smell is pungent, dizzy, and I want to vomit. Long-term sun exposure will produce toxicity after oxidation, so consumers should not install it.

Identification methods. 1. After tearing the transparent layer of the solar film, smell the smell, if it is a fake film, there will be an unpleasant smell emitted, and the real film will not have this phenomenon. If you look at the edge of the solar membrane after tearing it by hand, you can see it with the naked eye, and although the solar membrane is very thin, you can still see that it is divided into several layers. It is important to note that some businesses in the market will deliberately confuse the infrared blocking rate with the total solar insulation rate.

2. In terms of visual experience, high-quality solar film can see items 6 meters away at night, while low-quality film does not meet this standard or appears foggy;High-quality solar film is not easy to change color, and it will not decolorize when scraped with a scraper during construction, while the color of low-quality film is easy to fall off, and it is easy to fade after a period of use.

3. High-quality solar film feels heavy and smooth to the touch, while low-quality solar film feels thin and brittle. If the car owner does not believe in the equipment used by the car decoration store to demonstrate the thermal insulation of the solar film, you can take a piece of solar film and put it on the face towards the sun, how the thermal insulation effect of this film is, you can quickly feel it yourself.

Through the identification of these "soil" methods, without the need for sophisticated equipment, the owner himself can know the advantages and disadvantages of the solar film, so that the original form of the inferior film is exposed.
