Frequently Asked Questions
1. What materials are used for the insulation of the prefab house?
The walls and roofs utilize high-quality sandwich panels including EPS, PU, Glass Wool, and Rockwool. For the ceiling, 80mm fiber glass insulation is standard to ensure thermal efficiency.
2. Is the modular house resistant to extreme weather and earthquakes?
Yes, the structure is engineered to withstand 90 km/h wind speeds and 80 kg/m² snow loads. It is also rated for 7-degree earthquake resistance and 1st-degree seismic conditions.
3. How is the electrical and sanitary system installed?
Electrical installations are external with PVC cable channels, including keys, sockets, and lighting. Sanitary systems use PVC-based pipes for both clean and waste water, typically extending 1m outside the building.
4. What is the typical delivery time and assembly process?
The standard delivery time is approximately 35 days. Materials are designed for easy assembly; engineers can be sent to the site to guide installation and train local workers as required.
5. Can the prefab house be used for permanent residences?
While excellent for temporary offices and classrooms, the high-quality steel structure, full insulation, and custom interior options like solid wood flooring and plasterboard ceilings make it suitable for villas and long-term dormitories.
6. What certifications do these prefabricated buildings hold?
All products are manufactured under strict quality control and are certified by ISO 9001-2000, CE, SGS, and BV standards to ensure international quality compliance.
