One of the biggest selling points of car film is that it can insulate heat, and many sellers say that car film can achieve heat insulation in summer and keep the car warm in winter, so can it really do so much?
First of all, let's take a look at the role of heat insulation film in summer, solar heat radiation mostly enters the car through doors and windows to increase the temperature, which will cause an increase in fuel consumption. After the test is applied to the glass heat insulation film, the ineffective heat insulation rate reaches 50-85% on hot days, so that the temperature difference of the film is 3-5 degrees, and the air conditioning is reduced by more than 30%, making the car cool!
First, some people say that the glass film can keep warm in winter
Theoretically speaking, the heat insulation film does not have the function of heat preservation, and the heat insulation film on the glass has the following basic conditions, psychological effects: when we think that the heat insulation film has the effect of heat preservation, it will give itself a certain psychological effect.
Second, the heat insulation film and the insulation film are confused
Another important reason is that the thermal insulation film and the thermal insulation film are the same product, and the thermal insulation film can prevent the indoor temperature from dissipating quickly to a certain extent in winter, so as to achieve a certain thermal insulation effect, but our effect is incomparable with heating and air conditioning.
Third, regional differences between the North and the South
The impact of car film is still relatively large, the climate of the north and south has a great difference in development, in the winter in the north of our country dry and cold, the south is wet and cold.
