As an advanced thermal insulation material, the nano - microporous insulation board has received increasing attention in the market in recent years. Its development prospects are very broad, but at the same time, it also faces a series of challenges. From the perspective of development prospects, with the increasing global emphasis on energy conservation and emission reduction, the demand for high - efficiency thermal insulation materials in both the industrial field and the construction industry is continuously growing. The nano - microporous insulation board, with its excellent thermal insulation performance, can effectively reduce energy consumption, which is in line with the current trend of green development. In the industrial aspect, with the upgrading of manufacturing and the strengthening of environmental protection requirements, more and more enterprises need to adopt more efficient thermal insulation materials to improve production efficiency and reduce operating costs. This provides a broad market space for the nano - microporous insulation board. In the construction field, with the continuous improvement of building energy - saving standards, the nano - microporous insulation board is expected to become the mainstream exterior wall insulation and roof thermal insulation material. Especially in some large - scale public buildings and high - end residential projects, its excellent performance can meet the high requirements for building comfort and energy - saving effects. Moreover, with the rise of prefabricated buildings, the nano - microporous insulation board can be integrated with other building components to achieve the dual goals of rapid installation and high - efficiency energy conservation. However, the development of the nano - microporous insulation board also faces some challenges. First of all, there is the cost issue. Currently, its production process is relatively complex, and the cost of raw materials is high, resulting in a relatively expensive product price, which to a certain extent limits its large - scale promotion and application. Secondly, the durability and stability of the nano - microporous insulation board still need further research and verification. During long - term use, whether its thermal insulation performance will decline due to the influence of environmental factors, and whether its structure can remain stable are all issues that need to be addressed. In addition, market awareness is also a challenge. Although the nano - microporous insulation board has many advantages, because it is a new type of material, many users are not yet familiar with its performance and characteristics. This requires enterprises to strengthen market promotion and technical training to improve users' awareness and trust in the product. Despite the challenges, with the continuous innovation of technology and the gradual maturity of the industry, the nano - microporous insulation board is expected to overcome these obstacles and occupy an important position in the future market, making greater contributions to global energy conservation, emission reduction, and sustainable development.
