Is Prefabricated House Warm?

The thermal insulation performance of prefabricated houses is generally poor. This is elaborated from two aspects: joint issues and actual living experience.

Poor Thermal Insulation Due to Joint Issues

Prefabricated houses are usually assembled from prefabricated panels. During the assembly process, it is often difficult to achieve a completely tight fit at the joints of the prefabricated panels, resulting in certain gaps. These gaps serve as channels for heat transfer. In winter, the warm indoor air rapidly escapes to the outdoors through these gaps, causing the indoor temperature to drop quickly. In summer, the hot outdoor air floods into the interior through the gaps, leading to an increase in indoor temperature. The frequent occurrence of this heat exchange significantly affects the thermal insulation and heat-proofing performance of prefabricated houses, making it difficult for the houses to maintain a relatively stable and comfortable temperature.

Poor Actual Living Experience

Many homeowners living in prefabricated houses have profound experiences. Some residents report that in winter, their children's beds are always cold. Even with the use of various heating devices, it is difficult to achieve an ideal warm state throughout the entire room. This is because the poor thermal insulation performance of prefabricated houses causes continuous heat loss, and the heat generated by heating devices is difficult to accumulate effectively indoors. In summer, the houses are stuffy and hot, as if one is in a "steamer". To alleviate this stuffiness, residents have to use air conditioners and other cooling devices for long periods. This not only increases electricity expenses but may also have a certain impact on physical health due to prolonged use of air conditioners. For example, some residents say that because of the poor heat insulation effect of prefabricated houses, the air conditioner has to be turned on almost all day in summer, resulting in high electricity bills and a certain financial burden on the family.

In conclusion, due to the characteristics of their own structure and assembly method, prefabricated houses generally have poor thermal insulation performance, which brings many inconveniences to residents during actual living.
