Spray PU foam is an advanced construction insulation material widely used in insulation for external walls and cold storages. Its unique performance and advantages make it an ideal choice in modern construction projects.
In terms of external wall insulation, spray PU foam is favored for its lightweight, durability, and superior thermal insulation properties. During the spraying process, the material forms a uniform thermal insulation layer, effectively blocking external cold or high temperatures, thus enhancing the building’s thermal insulation. Moreover, spray PU foam exhibits excellent adhesion and can adapt to various wall surfaces, making it an ideal choice for external wall insulation.
For foam spraying in cold storage, the excellent performance of spray PU foam is also fully realized. Due to its closed-cell structure, it effectively isolates external temperatures, ensuring a stable low-temperature environment inside the cold storage. Simultaneously, the spraying method ensures seamless adhesion of the insulation layer to the cold storage surface, reducing thermal bridging effects, enhancing the insulation performance of the cold storage, and reducing energy consumption.
China’s Real Estate Industry 2023
China’s real estate investment totaled CNY 11.09 trillion in 2023, a decrease of 9.6% from the previous year. Among this, housing investment amounted to CNY 8.38 trillion, a decrease of 9.3% year on year. The construction area of real estate developers in 2023 reached 8.38 billion square meters, a decrease of 7.2% from the previous year. Among these, housing construction area decreased by 7.7%. The newly started construction area was 953.76 million square meters, a year-on-year decrease of 20.4%, and new home construction area was 692.86 million square meters, down by 20.9%. However, the completed construction area was 998.31 million square meters, an increase of 17.0%, with completed home construction area reaching 724.33 million square meters, an increase of 17.2%.
In terms of sales, the sales area of commercial buildings in 2023 was 1.12 billion square meters, a decrease of 8.5% from the previous year, with home sales area also decreasing by 8.2%. The sales value of commercial buildings totaled CNY 11.66 trillion, down by 6.5% year on year, with home sales value also decreasing by 6.0%.
Renovation of Old Residential Communities in China 2023
Spray PU foam plays a crucial role in renovation projects, mainly used in roof insulation and waterproofing projects. In 2023, 53,000 old residential communities were planned to be renovated, according to the Ministry of Housing and Urban-Rural Development. Statistics from various regions indicated that 53,200 old residential communities commenced renovation from January to November 2023. It is estimated that the number of old residential communities included in the renovation project would increase by about 1% year-on-year in 2023. This demonstrates the widespread use of spray PU foam in renovation projects, providing robust support for the overall renovation of old residential communities.
Foam Spraying In Cold Storage 2023
Cold storage is the core node of the entire cold chain and a crucial link in the transportation of products, serving the functions of storage and transshipment. It’s frequently used for cold foods, meat and meat products, fruits and vegetables. China highly emphasizes the development of cold storage industry, with policies inclined towards the construction of cold chain logistics facilities for agricultural products storage and preservation. In 2023, China successively issued Modern Protected Agriculture Development Plan (2023-2030) and the Notice on Advancing Cold Storage Facilities Construction in Agricultural Producing Areas. The National Development and Reform Commission (NDRC) released the list of National Major Cold Chain Logistics Bases in 2023.
Cold Storage Capacity: China’s cold storage capacity reached 228 million cubic meters in 2023, an 8.3% increase year-on-year, according to China Federation of Logistics & Purchasing (CFLP) Cold Chain Logistics Committee. In H1 2023, cold storage construction projects that were delayed due to the pandemic gradually resumed, coupled with the demand for newly added cold storage projects during the year, resulting in the annual increase in cold storage capacity surpassing the overall demand growth. The rapid expansion of the prepared food industry and the active layout of related enterprises have become one of the main factors driving the growth of added cold storage capacity. China’s market size of prepared foods was about CNY 419.6 billion in 2022, a 21.3% year-on-year increase and the market is expected to exceed CNY 500 billion in 2023, according to the data from www.cnfood.com.
