Construction process (12 sheets)
Many modern buildings use glass curtain walls, large glass and floor-to-ceiling glass doors (balconies), which not only improve the room landscape, but also increase the solar radiation heat introduced into the room and increase the electricity consumption of room air conditioning. Air conditioning is the first killer of building energy consumption, accounting for 20% to 50% of building energy consumption.
In order to solve the above problems, the United States has developed a solar thermal insulation film, which has the functions of heat insulation, energy saving, ultraviolet protection, beauty and comfort, safety and explosion protection, and effectively and conveniently solves many problems caused by glass, just like the car film will stick the glass together when the car collides.
The film pasted on the surface of automobile glass, commonly known as automobile film and explosion-proof film, was originally called solar film, so as the name implies, automobile film is used to deal with the scorching sun and ultraviolet rays in summer. Explosion-proof membrane has explosion-proof function besides heat insulation and light isolation. High-quality explosion-proof film uses special polyester film as the base material, and the film itself has strong toughness and is equipped with special pressure-sensitive adhesive. When an accident occurs, the broken glass will be stuck by the car film and will not splash and hurt people. Automobile explosion-proof membrane also has the function of one-way perspective and reducing glare.
