Jinan Building Glass Door and Window Film Energy-Saving Building Materials Film In building energy-saving, building glass doors and windows are an important link that is very weak and often overlooked. However, it is also an area with great potential to be tapped in building energy-saving work. At present, many old buildings in our country use a large number of steel windows and aluminum windows equipped with ordinary transparent glass. Even in new buildings in recent years, especially residential doors and windows, ordinary transparent glass is still widely used. Doors and windows account for the energy consumption of the entire building envelope (exterior walls, roofs, doors and windows). In most areas of our country, there is sufficient sunshine and the temperature is usually above ℃. During the day, most of the outdoor solar heat radiation enters the room through glass doors and windows, causing the room temperature to rise. It is necessary to increase the cooling load to offset the heat.
Indoor cooling energy is lost through the glass at night, thus greatly increasing energy consumption. This is a direct reason for the high energy consumption of buildings. One of the effective solutions is to use new energy-saving glass doors and windows to minimize the transmittance of solar radiation. People may have noticed that the glass used in doors and windows of buildings in our country is undergoing a development process from ordinary white glass to darker heat-absorbing glass (commonly known as brown glass) to light green heat-absorbing glass, coated glass, and light green insulating glass. Because light green glass is cheap and has a certain thermal insulation effect, it is widely used in the doors and windows of ordinary residential buildings. Insulated glass has good sound insulation and heat insulation properties, and is gradually being used in the doors and windows of newly built high-end luxury homes. However, its The high price also restricts popularization and promotion. Moreover, the above-mentioned types of glass have one of the most fatal weaknesses of ordinary glass, which is that it is brittle and fragile, which means that the safety performance of the glass is low.
How can buildings adopt effective, economical and convenient methods to solve the problem of heat insulation and energy saving of building glass doors and windows and improve their safety performance? Multifunctional glass film is a high-tech energy-saving product that can effectively control solar thermal radiation and increase the strength of glass. It is a new type of energy-saving building material.
This kind of film is made of a special polyester film as the base material. The middle of the polyester film is coated with various high-reflectivity metal or metal oxide coatings using magnetron sputtering and other methods. A functional glass film that is both light-transmitting and highly heat-insulating, made of composite lamination using a special process. It can transform cheap ordinary transparent flat glass into safety insulating glass with multiple colors and functions. For example, a film can be directly attached to ordinary transparent glass to turn it into insulating glass like coated glass, and ordinary transparent glass can be turned into safety insulating glass with both heat insulation and safety and explosion-proof functions. A colored or colorless transparent safety film can also be affixed to the curtain wall glass to make the coating layer of the coated glass less likely to oxidize, fade and fall off, and increase its ability to resist wind and acid and alkali erosion.
According to tests, ordinary glass affixed with a safety bulletproof film can prevent the shooting of micro submachine guns without penetrating and without splashing, which shows its reliable impact resistance. Safety glass made of ordinary glass with a safety film has reliable safety performance, is low-priced, and can significantly reduce the weight of the glass. Explosion-proof glass is made by pasting special safety glass on ordinary glass with a certain thickness. In the event of an explosion, it can effectively withstand the shock wave generated by the explosion, reducing direct damage and damage from flying glass fragments. It can also reduce the number of bombed facilities. and repair costs for facilities near the center of the explosion.
