In the field of building energy conservation, a new material called silica aerogel is attracting wide attention. This material, known as' solid air ', is reshaping the future of building insulation technology with its excellent thermal insulation performance.
Silica aerogel is an ultra light solid material composed of silica nanoparticles, and its porosity is as high as 99.8%. This unique structure results in a thermal conductivity as low as 0.013W/(m · K), far lower than traditional insulation materials. In practical application, only a 1cm thick aerogel layer can achieve the effect of 10cm thick traditional thermal insulation materials.

Recently, a large domestic construction group successfully applied silica aerogel to the energy-saving reconstruction of a high-rise building. The renovated building has reduced energy consumption by 40%, significantly reduced indoor temperature fluctuations, and greatly improved living comfort. The project leader said: "Silica aerogel not only improves the energy-saving effect of buildings, but also saves a lot of space, providing more possibilities for architectural design."
However, the promotion of silica aerogel still faces some challenges. First is the cost. At present, the price of aerogel is 5-10 times that of traditional thermal insulation materials. Secondly, the complexity of construction technology requires a professional construction team and special equipment. But with the advancement of technology and large-scale production, these problems are gradually being solved.
Industry experts predict that with the continuous improvement of building energy efficiency standards, the market demand for silica aerogel will continue to grow. It is estimated that by 2025, the global market size of aerogels for construction will reach US $5 billion, with an annual growth rate of more than 30%.
Many enterprises are increasing R&D investment and developing new aerogel products. A science and technology company recently introduced a flexible aerogel composite material, which not only maintains excellent thermal insulation performance, but also greatly improves the strength of the material and construction convenience. The launch of this innovative product is expected to accelerate the application of aerogel in the construction field.
With the continuous progress of technology and the continuous decline of cost, silica aerogel is expected to become the mainstream material for building energy conservation in the future, providing a strong driving force for the development of green buildings.
