Is thermally insulating sunscreen glass film useful

Car thermal insulation glass film is useful. The thermal insulation film of the vehicle can be divided into two types. One is the metal film, which uses the principle of metal reflection to reflect the infrared rays of the heat carried in the sunlight to achieve the effect of long-term heat insulation.

Car window film can insulate heat and protect the sun.The window film has seven functions, heat insulation and sun protection, and the film can solve the large amount of heat generated by infrared rays. Ultraviolet protection. The medium and long waves of ultraviolet light can penetrate thick glass. The thermal insulation film can block most of the ultraviolet rays, prevent skin damage, and also reduce the aging of the car interior. Safety and explosion-proof.

The function of automobile film is to increase aesthetics, increase private space, safety and explosion, heat insulation and sun protection, anti-glare, ultraviolet protection, and reduce air supervision and consumption. Can such a good car film really protect you from sun and heat? Good quality car sunscreen film does have the effect of sun protection and heat insulation.

Improve the indoor environment. Glass thermal insulation film can improve indoor comfort, reduce dryness and heat, and also weaken strong light and improve the indoor environment. Isolated from ultraviolet rays.

Install a glass insulation sunscreen film to filter strong light and make the indoor environment more comfortable.Heat preservation and energy-saving building glass insulation film is warm in winter and cool in summer, reducing energy consumption and reducing the cost of air conditioning and heating. The privacy protection film has the effect of not being peeped, maintaining clear perspective and actual privacy.

The role of automotive thermal insulation film

Car window insulation film can block ultraviolet rays , block some heat and protect personal privacy.

Save energy consumption. Apply a heat-insulating and explosion-proof film to your car, which can effectively block the heat source and heat conduction, so that the cooling effect is no longer discounted and reduce fuel consumption. The authoritative department verified that after installing the car with thermal insulation film and explosion-proof film, the average energy savings of the car reaches 3%.

The advantage of car film is to block ultraviolet rays, block part of the heat, and prevent injuries caused by sudden bursting of the glass. At the same time, according to the one-way perspective performance of the solar film, it achieves the purpose of protecting personal privacy. In addition, it can also reduce the energy consumption of air conditioning, improve the aesthetics, and achieve the effect of saving fuel consumption at some levels.

Related introduction: The function of thermal insulation film: good thermal insulation effect, reducing the temperature of the car can reduce the burden of air conditioning and save fuel. Working principle: The thermal insulation film is mainly beneficialHeat insulation with radiation and convection can have higher thermal insulation performance than automobile glass film without a reflective layer without deepening the color of the automobile glass film.

What are the functions of thermal insulation film? The thermal insulation membrane mainly has the functions of blocking heat, filtering strong light, reducing heat loss, explosion-proof and scratch prevention. For a detailed introduction to the function of thermal insulation film, please read the following. Blocking heat. Professional heat-insulating explosion-proof film can block 40-60% of solar heat, significantly reducing the temperature in the car and improving the comfort in the car.

Apply a thermal insulation and explosion-proof film to your car, which can effectively block the heat source and heat conduction, so that the cooling effect is no longer discounted and reduce fuel consumption. The authoritative department verified that after installing the car with thermal insulation film and explosion-proof film, the average energy savings of the car reaches 3%.

What kind of film is good for car insulation?

Car thermal insulation film brand: Dragon film Dragon film brand car film has a good reputation in the industry, and the quality is also good. But after all, it has just entered the market, it is not easy to sell, and the price of dragon film is also high. Now the car film of the Long film brand costs between 2,000 and 3,000 yuan.

Now the consumption level of car owners is also improving. With the popularization of car maintenance knowledge, more and more car owners will choose more cost-effective products.

The brands with the best thermal insulation effect of automotive film are Weigu, LLUMAR Dragon Film, Ruidun, 3M, Meiji, etc. Weigu Shanghai Haiyan Weigu International Trade Co., Ltd., a well-known brand of glass film. One of the most competitive brands in the world automotive thermal insulation film market, it is an intelligent glass film that can screen the spectrum in the world.

The thermal insulation rate of automobile membrane is generally appropriate

However, relatively speaking, the front gear requires a high light transmission rate, and a thermal insulation rate of 55% is generally good. However, products that claim to be 100% thermal insulation basically do not exist. UV protection rate is not important: for female car owners, sun protection in summer is an important issue. Strong ultraviolet rays are a disaster for our skin and car interior.

"Explosion-proof film" is a second-generation product, which uses new adhesive and thicker film to improve the explosion-proof effect. It has certain heat insulation and sun protection performance. The thermal insulation rate is between 20% and 60%, and the ultraviolet insulation rate is about 80%.

Heat insulation rate: This indicator can be directly felt by the car owner, and there are many products on the market.The thermal insulation rate marked by the film is more than 80%. In fact, the thermal insulation rate of the automobile membrane is generally between 40% and 70%, which is true and reliable. And only some high-end films containing ultra-thin metal coatings can meet these indicators.

Total solar penetration rate: the sum of the solar energy through the glass/glass window film composite layer and the absorbed solar energy radiating inward. The unit of measurement of thermal insulation is the heat passing through per square foot per hour (BTU/Hr. /Ft.2, of which 1BTU=262 cards).

How is the car glass film insulated?

Glass thermal insulation film is used to reflect infrared rays by adding a layer or even multiple layers of metal inside to achieve thermal insulation performance.However, because it is thermal insulation for infrared rays, it has a good effect, and it has a high light transmittance, and the heat insulation can also transmit light.

Car glass thermal insulation film can indeed insulating heat. Moreover, the car glass thermal insulation film can not only block the heat in the sunlight, but also block ultraviolet rays, prevent glass splashes from injuring the people in the car or others, and also play an anti-glare effect.

Car film can be insulated. Car glass film, car explosion-proof film, car film are attached to car glass to control sunlight.

Thermal insulation film mainly uses the form of radiation and convection to insolate heat. It is mainly to prevent the radiant heat of the sun.

The principle of automobile thermal insulation is that the key to the thermal insulation film uses radiation sources and transmissions to insulating heat, and the key is to avoid the thermal radiation of the sun.

Car film is a layer of film-like objects applied to the front and rear windshields, side window glass and sunroof of the vehicle, and this film-like object is also called solar film or explosion-proof thermal insulation film.
