Classification of building film

Building membranes are divided into three categories according to their functions and application scope: building energy-saving membranes, safety explosion-proof membranes and indoor decorative membranes.

Building energy-saving membrane, as its name implies, is a kind of glass membrane applied to windows and doors and curtain walls of residential buildings, office buildings, commercial buildings and other buildings to improve the indoor environment and reduce the energy consumption of refrigeration and heating through sunlight control, so as to achieve energy-saving effect. It is widely used in home, office, leisure and other places. In summer, building film can greatly reduce the cooling cost of air conditioners by blocking up to 79% of the solar heat energy; In winter, indoor heat loss through windows not only makes indoor staff feel uncomfortable, but also increases unnecessary energy consumption costs. The first-line brand high-quality energy-saving film installed on the internal surface of ordinary glass can reduce the heat loss by up to 30%, thus achieving the role of indoor warmth in winter.

The main purpose of building film is energy conservation and heat insulation, and it also has UV protection and certain safety functions. This kind of film can also be divided into heat reflection film and low radiation film. The thermal reflective film, which is pasted on the glass surface, enables the room to pass through part of visible light and part of near-infrared light, reflect and absorb part of visible light and part of near-infrared light, thus allowing enough light to enter the room and reflecting most of the heat of solar energy back, so that the indoor temperature will not rise too much in hot summer, thus reducing the indoor air conditioning load, Achieve the effect of saving air conditioning costs and energy conservation. Low radiation film, which can penetrate a certain amount of short wave solar radiation energy to make the solar radiation heat enter the room and be absorbed by indoor objects; At the same time, it can retain more than 90% of the long wave infrared reflection of indoor object radiation indoors. The low radiation film can make full use of solar radiation and long wave radiation energy of indoor objects. Therefore, it can be used in cold areas and heating buildings to achieve heat preservation and energy conservation.

The construction safety film is pasted on the glass. When the glass is broken due to various reasons, the fragments are stuck by the construction safety film, reducing splashing and falling. At the same time, the strength of the membrane body enables the membrane and glass to bear external forces together, and in the case of glass breakage, they can bear certain external forces alone for a period of time. Therefore, the use of construction safety film greatly improves the safety of glass.
