Frequently Asked Questions
1. What is the expected service life of these modular buildings?

The standard service life is 30 years, though with proper maintenance and standard environmental conditions, the life cycle can extend up to 50 years.

2. Can the container units be stacked or expanded?

Yes, the system allows for unlimited compounding in longitudinal and transverse directions. Units can be stacked up to 2 floors for residential use and 3 floors for warehousing.

3. What kind of foundation is required for installation?

Units can be mounted on a flat solid surface like asphalt or concrete, on point foundations (concrete cubes), or on band foundations depending on the site requirements.

4. Is the building fire-resistant?

Yes, the wall and roof panels use noncombustible mineral wool insulation. Fire ratings meet GB 12955-91 (36 minutes) and BS 476 (20 minutes) standards.

5. Are the units insulated for extreme weather?

The units feature high-density mineral wool or polyurethane insulation (50mm to 120mm options) providing excellent thermal resistance (U-values as low as 0.37 W/m²k for floors).

6. What certifications do these buildings hold?

Our modular systems are fully compliant with ISO standards, CE certification, and the components are RINA certified for dimensions, weight, and payload.
