Do New Houses Use Prefabricated Panels?

Nowadays, prefabricated panels are rarely used in newly constructed houses, with cast-in-place methods being more prevalent.

Situation of Newly Built Urban Residences

In the field of newly built urban residences, the use of prefabricated panels has become less common today. In the past, building houses with prefabricated panels was relatively widespread. However, with the advancement of construction technology and the increasing demand for building quality, the drawbacks of prefabricated panels have gradually emerged. Prefabricated panels have poor overall integrity, and their seismic performance is relatively weak when facing natural disasters such as earthquakes, making it difficult to ensure the structural safety of buildings. Moreover, if damage occurs during the later stages of use, repairing and replacing prefabricated panels can be cumbersome, requiring significant manpower and material resources. In contrast, cast-in-place houses have distinct advantages. The cast-in-place process ensures good overall integrity of the house, with all parts tightly connected to form an organic whole, greatly enhancing seismic performance and improving structural safety. At the same time, the maintenance costs of cast-in-place houses are relatively low in the long run, and the overall costs may be more advantageous. Therefore, most newly built urban residences adopt more advanced construction methods such as cast-in-place.

Situation of Rural Self-Built Houses

In rural self-built houses, prefabricated panels were commonly used as roofs in the past, mainly due to price considerations. Prefabricated panels are relatively inexpensive, making them a more economical choice for rural families with limited financial resources. However, prefabricated panels also have numerous issues. They are prone to leaking, affecting living comfort; they have poor thermal insulation, making it difficult to maintain indoor temperatures in winter and increasing heating costs; their sound insulation is poor, allowing external noise to easily enter the house and affecting residents' quality of life; and they have a limited lifespan, potentially experiencing aging and damage after a period of use, requiring frequent repairs or replacements. With the development of the rural economy and the increasing demand for living quality among residents, more and more rural self-built houses are also starting to adopt higher-quality building materials and construction methods to enhance the performance and quality of their houses.
