1、 Industry demand
Energy consumption of building insulation in China
The construction industry is one of the fastest growing industries in China's energy consumption. Currently, the total area of existing buildings in urban and rural areas is about 40 billion square meters. During the use of these buildings, the energy consumed in heating, air conditioning, ventilation, lighting, and other aspects accounts for about 30% of the country's total energy consumption. With the rapid development of the real estate industry in recent years, this proportion is also increasing year by year. According to the experience of developed countries, the proportion of building energy consumption in China's total social terminal energy consumption will gradually increase to about 35%. Therefore, it is necessary to attach importance to building energy-saving projects, significantly reduce energy consumption, alleviate the contradiction between energy supply and demand in China, reduce environmental pollution and greenhouse effect, and maintain the sustainable development of the national economy. Strengthening the design and development of green buildings, and carrying out urban construction through green environmental protection and low-carbon emission reduction, can not only reduce resource consumption, achieve maximum utilization of resources and energy, improve urban economic and social benefits, but also significantly improve living conditions and enhance the quality of people's living environment.
Application in the construction market
China Building Thermal Design Zoning
China has a vast territory, and energy-saving and insulation solutions for buildings in different regions should also be adapted to the local climate, make reasonable use of local climate resources, and build the most reasonable building insulation system.
2、 Industry pain points
(1) Construction difficulties
Traditional insulation materials can become quite troublesome in the renovation of old houses, requiring changes to the external wall structure of existing buildings, and external air conditioning equipment and drainage pipes on the walls can also have an impact on the construction.
(2) Wall detachment
The traditional method of external wall insulation is the external pasting method, which involves bonding the insulation material to the surface of the wall with mortar and covering it with a decorative layer. This method is greatly affected by factors such as construction quality and external environment, which can easily cause cavities inside the bonding, further leading to cracking and hollowing, ultimately causing wall detachment and accidents, directly threatening the safety of residents' lives.
(3) Environmental pollution
Traditional insulation mortar construction involves multiple processes, is complex, has a long construction period, has a significant impact on the surrounding area, and generates a large amount of construction waste. It is not suitable for existing building renovation projects that belong to the "simultaneous construction and operation" engineering type.
(4) Wall thickening
The insulation layer is placed inside the wall, reducing the usable area of the commercial housing; Secondly, it affects the secondary decoration of residents. Heavy objects such as decorative paintings cannot be hung on the indoor walls, and hanging and fixing objects on the interior walls can easily damage the internal insulation structure.
(5) Decoration pollution
Nowadays, with the increasing emphasis on health, green environmental protection has become the primary consideration in home decoration.
(6) Poor insulation effect
Most reflective thermal insulation surface coating has only heat-reflecting function, which means keeping the heat form outside the house from passing through the wall. Therefore it has almost no insulation function. It could only decrease few tempreature in Summer, but it is unable to keep the house warm in Winter.
3、 Solve the problem
(1) Convenient construction
SNTZ-100 aerogel thermal insulation thick medium is applied to the reconstruction of existing buildings without changing the external structure of the existing building
wall, or dismantling the external air conditioning equipment and drainage pipes on the building wall. It is convenient for construction and belongs to the engineering
form of "construction while operation".
(2) Wall safety
SNTZ-100 aerogel insulation thick medium coating construction thickness is only 2mm, far less than traditional insulation materials, which can effectively avoid falling off
and other problems.
(3) Green construction
SNTZ-100 insulated thick medium coating can be continuously applied without producing joints, effectively avoiding gap leakage. It has fewer processes, simpler
construction, shorter construction period, lower cost, less impact on the surrounding area, and does not generate a large amount of construction waste.
(4) Save space
SNTZ-100 aerogel thermal insulation thick intermediate coating only needs a thin thickness of 2mm, which is equivalent to several centimeters of traditional thermal
insulation materials. The space occupied by interior wall decoration can be ignored, so as to maximize the living space.
(5) Environmentally friendly and reassuring
SNTZ-100 aerogel thermal insulation thick intermediate coating material is pure and odorless, with stable physical and chemical properties, no release of harmful
substances, and meets environmental requirements. At the same time, it is a paste state that can be processed and mixed with a small amount of water on site, so as not
to generate dust and affect construction personnel and the surrounding environment.
(6) Thermal insulation
SNTZ-100 aerogel thermal insulation thick medium coating+SNTZ-101 nanometer reflective thermal insulation coating, warm in winter and cool in summer, good thermal
insulation effect, energy conservation and consumption reduction, and convenient construction.
4、 Typical case
(1) Air gel thermal insulation coating system for external wall insulation of new residential quarter
A coating thickness of 2mm can achieve a total thermal resistance value of 0.5m2 * K/W, which meets the requirements of Appendix B.4 of the national standard GB 50176-2016 "Thermal Design Code for Civil Buildings" of 0.04m2 * K/W.
(2) Air gel thermal insulation coating system for renovation of old residential areas and house repair
---Convenient construction not only meets the appearance requirements but also responds to the national building energy conservation requirements.
(3) Air gel thermal insulation thick medium coating for interior wall insulation of home decoration
---Without using air conditioning or heating, the indoor temperature difference before and after painting can reach 3-5 ℃, which is energy-saving, noise reducing, and
convenient for construction.
(4) Air gel thermal insulation coating system for building roof thermal insulation
---Easy to construct, waterproof and insulated, with a temperature difference of up to 10-15 ℃ under direct sunlight in summer.
(5) Air gel insulation thick medium coating for basement damp proof and mould proof
---The 2mm thick aerogel intermediate coating can prevent the basement wall from mildewing and delamination due to condensation water in moisture regain weather.
