Building film is the use of PET (polyethylene) substrate, the leading multi-layer metal sputtering technology and vacuum technology and ion technology and film physics, fine chemical technology, it has a very high thermal insulation efficiency, high tension, high elongation, Strong acid and alkali resistance. And the natural color rich, the test results show that 81% of the solar energy can be blocked; in the outdoor temperature of 38 ℃ ~ 39 ℃, 3.5 ℃ lower than the average glass temperature, saving more than 30% of the air conditioning power consumption, high-tech and energy saving material.
The main purpose of building film is energy-saving insulation, take-out UV and safety features. building films can also be divided into heat-reflective film and low-e film. Heat-reflective film, this building membrane attached to the glass surface so that the room can transmit visible and near-infrared light, but can not transmit far-infrared light. So there is enough light into the room, and most of the solar heat will be reflected back in the hot summer to keep the indoor temperature will not rise too much, thereby reducing the indoor air conditioning load, to save air conditioning costs and energy saving effect. Low-radiation film, this architectural film through a certain amount of short-wave solar radiation, the solar radiation heat into the room, absorbed by the interior objects; at the same time can be more than 90% of the long-wave infrared radiation indoor objects remain indoors. Low-e film can make full use of solar radiation and long-wave radiation of indoor objects. Therefore, in cold areas and heating buildings can be used to play insulation and energy saving effect.
Building membrane, as the name implies, is used in building windows and doors, curtain wall glass, decorative glass and other locations in residential, office buildings, commercial buildings to meet the diverse needs of different environments. From a professional point of view, architectural films are multi-layer polyester films made by vacuum multilayer, ion, and thin-film physics, fine chemical technology, with excellent strength and durability, due to different processing methods Have different functions.
Building membranes can be broadly divided into three categories based on their application: energy-saving membrane, safety explosion-proof membrane, interior decoration film. Has the following six major functions:
Efficiency and Energy Efficiency——Reducing heat inflow in summer and lowering air-conditioning costs to bring about energy efficiency;
Improve the indoor environment ——improve indoor comfort, less hot and dazzling glare；
To decorate the appearance of the building——to make the building and living room everlasting, different style and interior echo and complement each other, beautify the appearance of the building;
UV light Resistance—— can greatly reduce the solar heat and visible light into the room, 100% cut off ultraviolet light, to protect the building indoor items damaged, and reduce the harm to the body;
Security——ordinary glass in the face of wind, rain, impact damage will produce a large number of glass fragments, the personal and property hazards, after the film, even if the glass has become fragmented will be bonded into a whole, greatly enhance safety Sex
Privacy ——one-way perspective to meet the needs of viewing the outside landscape but also to protect the privacy of the two-way.
Building insulation film, that is, heat insulation window film, as the name implies, is a kind of film used on building window glass, which is mainly used to block outdoor heat from entering the room. Especially in the hot summer, a large amount of radiant heat enters the room, The temperature is extremely high, affecting the normal work and life comfort, and building insulation film can block more than 90% of the indoor heat, played an irreplaceable role.
Building insulation film structure principle:：
The main components for the polyester substrate (PET), anti-planning layer, plastic film, protective film. PET has a durable, strong moisture resistance, high temperature characteristics, so that building insulation film has a good thermal insulation effect.
Building insulation film main application position:
Building exterior glass curtain wall, large windows, balcony floor to ceiling windows, landscape rooms.
Building insulation film energy-saving effect:
In summer, the infrared rays in the direct sunlight carry a large amount of heat and greatly increase the indoor temperature, thereby greatly increasing the frequency and time of air-conditioning use and increasing the energy consumption. After the heat-insulating film is used, the heat can effectively prevent the heat from entering the room and thus save energy. Winter, the outdoor temperature is relatively low, while the ordinary glass can not stop the heat outflow, only after the foil can play a very good energy-saving purposes.
Building insulation film generally larger price differences, ranging from a few hundred dollars to several thousand dollars, and "a price for a share of goods," the price of the corresponding insulation effect is also a world of difference. The infrared barrier is a high-tech, difficult technology, so do not be tempted in the selection of temporary cheap, you want to achieve a safe and comfortable life and the effect of energy-saving emission reduction, the need to throw the price carefully buy.
Building energy-saving membrane (energy-saving window film), is a film made of special materials, through the paste on the glass to achieve the effect of saving energy consumption. And insulation film has the same purpose, by reducing outdoor heat into the room or reduce indoor heat loss method, thereby reducing indoor air conditioning or heating equipment, energy consumption, energy saving and emission reduction effect.
Building energy-saving film main features:
The main effect in winter. Due to the low outdoor temperature in winter and the high indoor temperature, ordinary glass can not block the heat exchange between indoor and outdoor. After using the energy-saving window film, the post-heating can reduce the indoor heat loss so as to achieve good thermal insulation effect and indirectly reduce the heating cost in winter.
The main effect in the summer. Summer outdoor temperature is high, leading to frequent use of cold air conditioning and other indoor air-conditioning, energy consumption is huge. The energy-saving window film can greatly reduce the solar heat into the room, thereby significantly reducing the cost of refrigeration to achieve energy-saving effect.
3、Blocking ultraviolet light
UV light is harmful, not only harmful to the human body, but also on the windows in front of the furniture, calligraphy and painting, such as carpet damage. Building energy-saving membranes block up to 99% of UV light entering the room.
4、Enhance indoor comfort
Direct sunlight causes indoor work and life to reduce comfort, and indoor mental state will have a significant negative impact on the architectural glass foil treatment can effectively prevent this from happening.
