Prospect of Application of Building Film

With people's requirements for low-carbon life, building safety and energy saving are placed in the primary position of architectural design and material selection. However, the glass design which pursues large area day-lighting has become a trend in modern architecture, which contradicts the tendency of energy-saving in architectural design.

If transparent glass is used in the building, too much sunlight and heat energy will enter the room in summer, and in winter, it can not prevent the overflow of indoor heat energy, and the cost of maintaining indoor appropriate temperature can only consume a lot of energy consumption of air conditioning or heating. How can we effectively reduce energy consumption? Building film is a good choice.

The following figure is the heat insulation effect diagram of the building film SH-012P product of Changzhou Sanyou Dissan Protective Material Manufacturing Co., LTD., which has passed THE CTC energy-saving certification. It can be seen from above that the total barrier rate of solar energy has increased from 9% before the film to 81% after the film, which greatly reduces the energy consumption of air conditioning and refrigeration. At the same time, due to the advantages of low production cost, convenient installation, light product, small impact on the bearing of the building, so that it can occupy a large market share in the transformation of energy-saving buildings or new buildings, the improvement of glass curtain wall structure.
