Prefabricated Panels for Rural House Floors

There are many hidden dangers in using prefabricated panels for rural house floors, and it is not recommended to adopt them.

Poor Integrity: Prefabricated panels are pre-made floor components. During construction, they are directly placed on both sides of the wall. Even if a ring beam is poured, their overall integrity is far inferior to that of a structure where the ring beam and floor are poured together. When subjected to external forces such as earthquakes or strong winds, separation and misalignment between the prefabricated panels and the wall are prone to occur, leading to damage to the house structure and affecting living safety.

Prone to Cracking and Leakage: There are gaps in the middle of prefabricated panels, which is an inherent defect in their structure. Over time, due to factors such as uneven settlement of the house and thermal expansion and contraction caused by temperature changes, these gaps are particularly prone to cracking. Once cracked, rainwater will seep into the room along the gaps, causing mold and peeling on the walls, affecting the service life and living comfort of the house. Moreover, repairs are relatively difficult, requiring re-treatment of the gaps and proper waterproofing measures.

Poor Sound Insulation: The material and structure of prefabricated panels determine their poor sound insulation performance. Normal activities of upstairs residents, such as walking, talking, and moving furniture, can be clearly heard downstairs, seriously affecting the quality of life of downstairs residents and easily causing conflicts between neighbors.

Short Service Life: The service life of prefabricated panels is generally only about 30 years. In actual use, problems such as cracking and leakage may occur after about ten years. As the service life increases, their performance will gradually decline, requiring frequent repairs and reinforcement, which increases usage costs.

Poor Thermal Insulation: The thermal insulation performance of prefabricated panels is poor. In summer, they cannot effectively block external heat from entering the room, causing the indoor temperature to rise and requiring long-term use of air conditioners for cooling, which increases electricity expenses. In winter, they cannot well retain indoor heat, resulting in lower indoor temperatures and requiring more energy for heating.

Policy Impact: By 2025, due to factors such as the policy direction of the Ministry of Housing and Urban-Rural Development, the accelerated promotion of urban village renovation, and new safety regulations for rural self-built houses, prefabricated panel houses may face demolition. This means that rural houses built with prefabricated panels may lose their use value in the short term, causing economic losses to homeowners.
