Are Prefabricated Panel Houses Good?

Prefabricated panel houses have many problems and are not ideal. It is not recommended to choose traditional prefabricated panel houses.

Extremely poor earthquake resistance: Traditional prefabricated panel houses have almost zero earthquake resistance and poor integrity. In the event of an earthquake, the floor slabs and walls are prone to instant separation and sudden collapse. Judging from the actual situations of past earthquakes, such houses have suffered severe collapses, resulting in a relatively high casualty rate and posing a great threat to the lives and safety of the occupants.

Vulnerable connection points: The connection methods between the prefabricated panels and the walls, as well as between the panels themselves, are simple and lack a rigid framework. When foundation settlement or wall cracking occurs, it can cause the panels to become misaligned and loose. Moreover, over time, the connection points will weather, the steel bars will rust, leading to a reduction in strength, and may even trigger a chain collapse accident.

Substandard materials: The phenomenon of cutting corners in the materials of prefabricated panels is relatively common, with high brittleness and easy breakage. In regular prefabricated panels, the steel bars are relatively thin, but some small workshops often use thin steel wires instead. The concrete grades do not meet the standards, and the thickness is also insufficient. When exceeding their load-bearing capacity, they will break instantly without any warning, posing a great safety hazard.

Poor thermal insulation and sound insulation: Traditional prefabricated panel houses have extremely poor thermal insulation and sound insulation effects. In winter, the interior feels cold; in summer, it is unbearably hot. At the same time, there is no privacy between neighbors, seriously affecting the living experience.

Short service life: Their designed service life is usually only about 40 years. Many houses have already been in use beyond their intended lifespan, showing problems such as peeling wall surfaces and wall cracks. Some have even become dangerous buildings and cannot guarantee the safety of occupants.

Low living comfort: The standardized and modular design makes the house appearance monotonous, with cramped interior space. The floor plan design lacks human-oriented considerations, resulting in relatively poor living comfort. In addition, the water leakage of prefabricated panels is much more severe than that of cast-in-place slabs.

However, nowadays, there are also upgraded versions of prefabricated houses, such as the E-MIC prefabricated concrete box house system, which has significant differences from traditional prefabricated panel houses.
