The door model of a lot of friends belongs to western bask, arrived summer house becomes particularly sultry, then the window affixts heat insulation film. So using window insulation film can really heat? Let's look at that in a second.
First, can the window insulation film really heat insulation
Window insulation film can insulate. The heat insulation film is usually dark in color and can effectively block sunlight. In the summer can effectively heat insulation, temperature can be separated from about 3.5 degrees Celsius, especially high-rise households, summer lighting time is longer, the sun is more dazzling. With the insulation, the room will feel colder.
The working principle of heat insulation film is to make aluminum, gold and other metals into multi-layer high heat insulation metal film through vacuum spraying or magnetron sputtering technology. When sunlight is direct on the window, the heat insulation film on the window is not bound by the nuclear absorption and light reflection. As the metal reflects it back, it is released again, taking some of the heat with it as the air outside moves. Therefore, the room temperature is lower than the temperature without the use of insulation film. The test results show that two rooms with the same conditions, the room with window film than the window without film saving 0.24 degrees/day.
But the heat insulation film can only give Windows on the original basis of some improvement, and did not completely solve the way of room heat insulation. It can only make the room less hot and save energy. If you want to make the window better insulated, it is recommended to choose hollow glass or make the glass area bigger.
Two, the window sunscreen heat insulation film when using matters needing attention
1, in the film above the glass, can not paste adhesive and other decorations in the window film, can not use adhesive to fix any items.
2. When cleaning the sunscreen and heat insulation film, spray the window film surface evenly with cleaning agent first, and then wipe the window film gently with a clean cotton cloth. If there are still stains, spray the cleaning solution again, wipe the window film from the top to the water level with wiper until dry, and wipe the edge of the window film with a dry cloth.
