With the continuous strengthening of people's awareness of environmental protection, people's desire to choose green products is getting stronger and stronger, forming a green wave in the field of global production and consumption. It is estimated that in the next decade, green products may become the leading products in the world's major commodity markets. Green products refer to products that adopt advanced technology in their life cycle, can meet the functional and performance requirements of users economically, save resources and energy, reduce or eliminate environmental pollution, and have good protection for workers (producers and users). 1, green refers to the impact of materials on the environment. The greenness of glazed hollow bead thermal insulation mortar is shown in the following aspects: (1) glazed hollow bead thermal insulation mortar takes glazed hollow bead as thermal insulation aggregate, and glazed hollow bead is an inorganic glassy mineral material, which is made by crushing and puffing volcanic rocks and contains no organic materials. In the process of use, it has stable physical properties, is non-toxic and harmless, does not emit harmful gases even in high temperature environment, does not cause aging and poor weather resistance, does not pollute urban air, and meets the requirements of modern people. (2) The raw materials of vitrified microspheres can make comprehensive use of China's rich mineral resources, turning waste into treasure, and non-renewable and exhausted resources are not used in material production. (3) Environmental protection is a remarkable feature of vitrified microsphere thermal insulation mortar, and there is no "three wastes" emission during its production and use, and there is no "environmental consumption" of existing organic thermal insulation materials in terms of air pollution, water pollution and radioactivity. 2, advanced technology (1) overall thermal insulation performance. Vitrified microbeads are coated thermal insulation materials, which form a whole with the matrix, and will not form thermal insulation cavities of plates, with stable structure and good seismic performance; At the same time, relying on the high cohesiveness of thermal insulation mortar itself, the damage to thermal insulation layer caused by wind pressure of clothes in high-rise buildings is completely solved; Moreover, it is easier to achieve thermal insulation for cold and hot bridge parts such as overhangs, parapets and air conditioning panels of external walls than plates, and the overall thermal insulation effect is better. According to thermal calculation, most of the structures coated with 3cm vitrified beads thermal insulation mortar can meet the national energy saving requirement of 50%. (2) Comprehensive performance. The glazed hollow bead thermal insulation mortar studied in this paper not only has unique thermal insulation performance, but also has sound absorption, air permeability, high temperature resistance, water resistance and frost resistance. As a complete thermal insulation system, vitrified bead thermal insulation mortar and polymer plastering anti-crack mortar have good crack resistance, aging resistance and weather resistance, and have strong ability to resist the erosion and destruction of thermal insulation layer by external environment in application, so the service life of products is long. This product has Class A fireproof performance and can be used as fire-fighting and fireproof material. 3. The economical (1) glazed hollow bead thermal insulation mortar has good thermal insulation performance, which meets the requirements of national energy-saving standards and can improve the thermal insulation performance of building envelope. At the same time, it has strong integrity, eliminates the phenomenon of hot bridge and cold bridge, and reduces energy loss. According to the thermal conductivity, every 1cm vitrified bead thermal insulation mortar is equivalent to 14cm brick wall. Equivalent to 30cm insulation effect. (2) Vitrified microsphere thermal insulation mortar is a single-component thermal insulation material with stable and reliable quality, good adhesion, early strength and quick drying, and short construction period. The construction speed is 3 times that of ordinary plastering and 2 times that of polystyrene particle thermal insulation mortar, which is obviously higher than other thermal insulation projects and greatly reduces the cost of thermal insulation system. Using this technology for external thermal insulation of external wall can reduce the total project cost without plastering mortar for the main structure. In addition, the system has excellent crack resistance, aging resistance, earthquake resistance and weather resistance, so it has long service life and low maintenance cost, so the "life cycle cost" of vitrified microsphere thermal insulation mortar is low. (3) Vitrified microbead thermal insulation mortar has excellent combination with decorative layer, and the necessity of using elastic coating is not emphasized. In addition, the requirements for base treatment are low, and leveling is not needed first, so the construction process is less, the materials are saved, the labor cost is low, it is suitable for construction, welcomed by construction workers, and the comprehensive cost is low. 4. Conclusion (1) As the most important part of building energy consumption, the external wall energy consumption accounts for the largest proportion in the whole building energy consumption, and its insulation directly affects the heat loss of the building, the design of heating system and the indoor thermal environment, so the research on its energy-saving technology has become the focus of building structure energy-saving research. (2) Vitrified bead thermal insulation system is a new type of external wall thermal insulation technology, which has the advantages of good color thermal insulation effect, low comprehensive cost and wide application range, which can greatly reduce building energy consumption and help alleviate the energy crisis in China. In addition, good thermal insulation performance further improves the stability and comfort of indoor buildings. (3) The purpose is to achieve the goal of building energy efficiency and promote the development of building energy efficiency in China by adopting economic and reasonable ways and methods on the basis of existing building materials and building structures. As a green thermal insulation form, vitrified beads thermal insulation system has excellent comprehensive performance on the premise of satisfying thermal insulation performance, which can bring remarkable social and economic benefits.

Plate moving, cutting and construction:
The fiber cement board itself is relatively heavy, and the whole uncut board needs at least two people to move. The thickness of 4mm-6mm belongs to thin plate, which is relatively fragile compared with thick plate. It needs to be moved carefully before installation, and it is easy to be broken and damaged if it is not protected.
It takes at least two people to install the fiber cement board, one to stabilize the position of the board and the other to fix it with special nails.
Cutting fiber cement board usually requires chainsaw or mechanical cutting machine, and there are three cutting methods:
1. Thin plates can be cut and broken with heavy tools.
2. Use fiber cutting machine (Australian cutting method)
3. Thick plates or high-density plates need chainsaw cutting.
Pay attention to the wind direction during board cutting, try to avoid inhaling powder, wear a mask or special protective tools, and board powder may cause diseases if it enters the lungs for a long time.
After the installation is completed, you can apply various paints for painting (waterproof paint is required for places exposed to the air). The joints of the fixed plates need to be filled with wood blocks, and the whole surface of the plates needs to be painted, which can prolong the service life of the plates. The maintenance workload of fiber cement board installation, fixing and painting is very small. Thick plates and high-density plates have good impact resistance, but thin plates and low-density plates need to be protected from external impact. Compared with wood wallboard, fiber cement board does not produce termites, is not easy to rot and has better corrosion resistance.
