Why do prefabricated houses have much better thermal insulation than traditional houses? ​

Under the general trend of energy conservation and carbon reduction, the thermal insulation performance of buildings has become the focus of attention. Prefabricated houses are changing people's perception of comfortable living with their excellent thermal insulation performance. What are its advantages? ​
Material: Build a strong thermal insulation line from the production end ​
The thermal insulation advantages of prefabricated houses have been established since factory production. When producing wall panels and roof panels, high-efficiency thermal insulation materials such as high-density rock wool, extruded boards, and polyurethane foam are accurately embedded. The thickness and density are strictly implemented according to the standards to avoid the problem of cutting corners that may occur in the on-site construction of traditional houses. ​
In addition, prefabricated wall panels adopt a composite structure of "outer protection + thermal insulation layer + inner support", which is like putting a sealed thermal insulation coat on the house to reduce heat loss caused by air convection. The thermal insulation layer of traditional brick-concrete houses relies on on-site filling, which is prone to gaps and the thermal insulation effect is discounted.​
Technology: Sealing technology creates a constant temperature environment​
The "heat leakage dead corner" of traditional houses greatly reduces the living experience, and prefabricated houses solve this problem through technological innovation.

Precise sealing grooves are reserved on the edges of prefabricated components. Special sealants and insulation strips are used for on-site installation with "mortise and tenon" splicing to make the components fit tightly and reduce air infiltration, the main cause of heat loss. At the same time, insulation wraps are made for beams, columns, window frames and other parts that are prone to forming thermal bridges to cut off the heat conduction channel. ​
In addition, the insulation layer of prefabricated components is moisture-proofed in the factory, and there is no wet operation during on-site installation to avoid the situation where the insulation materials become damp and fail in traditional construction. ​
Design: Personalized solutions for different climates​
Prefabricated houses can be "tailored" according to the climate of different regions. In the cold northern regions, thicker insulation layers are used to resist the cold, and in the hot southern regions, reflective insulation layers are integrated on the roofs to reduce solar radiation heat. ​
This design covers all enclosure structures such as walls, roofs, floors, doors and windows. For example, prefabricated floor panels are embedded in floor heating insulation layers and moisture-proof layers, and doors and windows use three-layer hollow glass and insulation profiles to form an all-round insulation system. ​
Effectiveness: Energy-saving and healthy, maintenance is more worry-free ​
The energy saving rate of prefabricated houses is 15%-20% higher than that of traditional buildings. The heating cost in the north is greatly reduced in winter, and the air conditioning operation time in the south is shortened by 20%-30% in summer.

Its good thermal insulation performance keeps the indoor humidity stable, avoids the problems of wall condensation and mold growth caused by insufficient insulation in traditional houses, and is more conducive to living health. ​
In long-term use, the modular design of prefabricated houses allows the insulation layer to be accurately located and partially replaced after damage, which saves time and effort in maintenance, while the cost of repairing the insulation layer of traditional houses is high and may also damage the original structure. ​
Conclusion ​
The thermal insulation advantage of prefabricated houses is the inevitable result of "factory production + modular design + systematic sealing". It can save energy costs and bring a comfortable living experience. Pay attention to the manufacturer's technical standards and certifications when choosing a house, and you can enjoy its "invisible benefits". In an era where energy saving and comfort are equally important, prefabricated houses are becoming the mainstream of future housing. ​
