Prefabricated Panels for Rural House Roofs

In the past, the use of prefabricated panels for rural house roofs was relatively common, but they have many drawbacks. Unless the budget is extremely tight, it is not recommended to use them; instead, cast-in-place concrete roofing is more recommended.

Prominent Waterproofing Issues: Prefabricated panel roofs have poor waterproofing performance, with a high probability of rain leakage. Data shows that 8 out of 10 households experience rain leakage, and it is difficult to guarantee 100% waterproofing. This is mainly because the joints between two panels are most prone to cracking and leaking. Once the joints are not properly treated, rainwater will seep into the house along the gaps, causing numerous inconveniences to the occupants and requiring frequent repairs and waterproofing treatments.

Poor Earthquake Resistance: Prefabricated panels have a low seismic coefficient and should not be used in earthquake-prone areas. During an earthquake, due to their structural characteristics, there is a lack of effective connection and integrity between the panels, making them prone to collapse and posing a serious threat to the lives of the occupants.

Poor Sound Insulation: The sound insulation performance of prefabricated panels is poor. Every movement upstairs, such as walking or talking, can be clearly heard downstairs, affecting the privacy and comfort of living and reducing the quality of life.

Poor Thermal Insulation: The thickness of prefabricated panel floors is generally around 12 centimeters. Although they are hollow structures, their thermal insulation performance is still poor. In summer, the indoor temperature will be very high, like a steamer; in winter, the indoor temperature will be very low, requiring additional insulation measures. Generally, a secondary roofing material covering is needed on the floor to compensate for this defect, increasing construction and usage costs.

Short Lifespan: The lifespan of prefabricated panels is relatively short, only about 30 years. Over time, the panels will experience aging, cracking, and other issues, requiring regular maintenance and replacement, which also brings a certain economic burden to the occupants.
