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.

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.
