Experience of Using Prefabricated Houses After Three Years
After three years of using prefabricated houses, the overall experience varies depending on the type, but they generally possess advantages such as structural stability and practical functionality, while attention to maintenance details is required to ensure long-term performance.
Cement Prefabricated Houses: Structurally Stable but Require Regular Maintenance
After three years of use, cement prefabricated houses demonstrate outstanding structural stability. The assembled cement houses produced by regular manufacturers are cast in one piece using C30 high-strength concrete, with an internal framework of national standard threaded steel bars. The overall safety factor is comparable to that of traditional cast-in-place houses, and factory standardized production ensures more stable quality and stronger earthquake resistance. However, due to material characteristics, issues such as local leakage and dampness may occur during the rainy season or high-temperature periods, especially at joints or weak points in the walls. For example, if the connection between the roof and the wall is not properly sealed, water leakage may occur due to thermal expansion and contraction; in high-temperature environments, the evaporation of internal moisture in the concrete may cause fine cracks, requiring regular inspection of sealants and reapplication of waterproof coatings for maintenance. Additionally, the high thermal conductivity of cement means that indoor insulation in winter relies on additional insulation layers or heating equipment, while in summer, shading measures are needed to reduce indoor temperatures.
Light Steel Villas: Significant Advantages in Comfort and Functionality
Light steel villas offer a good living experience over long-term use. Their thermal insulation performance is outstanding, with walls filled with efficient insulation materials such as glass wool or rock wool using light steel studs. The indoor temperature in winter is 3-5℃ higher than that of traditional houses, and in summer, it is 2-4℃ lower, significantly reducing air conditioning usage time and lowering energy consumption. The sound insulation effect is also excellent, with the combination of light steel studs and sound insulation materials effectively blocking external noise, making normal living noises (such as conversations and footsteps) almost inaudible indoors. In terms of earthquake resistance, the flexible system of the light steel structure can dissipate seismic energy through deformation, with almost no perception of earthquakes below magnitude 3 and a low risk of structural damage in magnitude 6 earthquakes. High space utilization is also a highlight, with light steel walls only 10-15 centimeters thick, saving about 30% of usable area compared to traditional brick walls, making them suitable for small units or scenarios with high space requirements.
General Advice: Regular Production and Standardized Maintenance Are Key
Regardless of the type of prefabricated house chosen, it is essential to prioritize qualified regular manufacturers to ensure that material quality and construction techniques meet standards. During use, cement prefabricated houses require a focus on waterproofing and damp-proofing, while light steel villas need regular inspection of wall connectors for looseness and aging of insulation layers. Daily maintenance can extend the house's lifespan to over 30 years, while neglect may lead to structural damage due to the accumulation of minor issues.
