Glass is an ancient building material, which appeared as early as the ancient Egyptian period. With the common development of human society, the glass industry has created a variety of glass with unique functions, which has enabled the glass family to continue to flourish. For example, bulletproof glass, photoelectric glass, vacuum glass, etc., all play an irreplaceable role in their respective fields. We will introduce the main types of glass window film and explain how to remove the old film from the glass.
The main purpose of architectural glass window film is energy saving and heat insulation, with UV protection and safety functions. This kind of film can also be divided into heat reflection film and low emissivity film.

Heat-reflective film. This film is attached to the glass surface so that the room can transmit visible light and near-infrared light, but not far-infrared light. Therefore, there is enough light to enter the room, and most of the solar heat is reflected back, and the indoor temperature will not rise too much in the hot summer, thereby reducing the indoor air-conditioning load, saving air-conditioning costs and saving energy.
Low-emissivity film, this film can transmit a certain amount of short-wave solar radiation energy, so that solar radiant heat enters the room and is absorbed by indoor objects; at the same time, it can retain more than 90% of the long-wave infrared reflections radiated by indoor objects in the room. The low-radiation film can make full use of solar radiation and the long-wave radiation energy of indoor objects. Therefore, it can be used in cold areas and heating buildings to achieve thermal insulation and energy saving effects.
How to remove the old film on the glass
1. Use soap to add a little mixture of ammonia and turpentine to remove the film on the glass.
