What you need to know about window film
Window film is a high-strength PET self-adhesive material affixed to the glass walls of buildings and other buildings, window film can greatly improve the toughness of the material and greatly improve the performance of the glass. The safety film adopts a unique mesh structure, which can increase the strength of the glass so as to withstand greater impact, which can increase the safety of the glass, and does not hurt anyone when the glass is broken; the privacy film adopts the advanced sputtering and coloring process, and sprays various non-ferrous metals onto the surface of the film layer through nanometer refinement, which can effectively reflect and refract the incident light to form a private effect; the window film is also coated with ultraviolet ray reflecting and absorbing agents, which can put the harmful wavelengths of ultraviolet rays are filtered out, thus protecting the furniture from fading and the skin from being harmed.
Different glass in the choice of window film has different requirements, general float glass mounted security film, in addition to calculating the thermal stress, but also must make the film after the glass impact performance of the falling ball to meet the “laminated glass,” the national standard of the falling ball impact performance requirements.
When installing safety film, the thickness should be selected according to the needs of the project, when the glass thickness and area exceeds a certain standard, the thickness of the safety film should be increased accordingly.
When installing energy-saving film, in addition to calculating the thermal stress, the heat transfer coefficient and shading coefficient of the glass should also be calculated after applying the film to ensure that the ideal energy-saving condition is achieved.
