What Fire Rating Should You Request for a Space Capsule House?

When purchasing a space capsule house, do not rely on a general statement such as “fireproof” or “high fire resistance.” Ask the supplier for test reports, fire-performance classifications, and the local building standard that applies to the complete unit. If fire safety is a primary concern, request rock wool sandwich panels, verify the tested wall and roof assemblies, and confirm that the electrical installation is suitable for the destination country.

Fire-Safety Priorities for Buyers

• Obtain fire-performance documentation for the complete wall and roof systems, including panel cores, surface layers, joints, doors, windows, and service penetrations.
• Rock wool is the listed panel-core option associated with fireproof performance and higher fire resistance. EPS is presented as a more economical insulation choice, while PU is selected mainly for low thermal conductivity and thermal insulation.
• Check that the proposed structure and electrical configuration comply with the regulations of the intended market. The product information states that the pre-installed electrical system can meet local standards in Southeast Asia, North America, and South America.
• Typical applications include construction camps, worker accommodation, emergency housing after disasters, cultural and tourism facilities, and new rural residential projects.

How to Evaluate the Actual Fire Performance

The fire rating of a modular or folding house belongs to the tested construction assembly rather than to the product name alone. Before placing an order, ask the manufacturer to list the insulation core, steel sheet specification, joint design, roof build-up, floor layers, doors, windows, cable routes, and penetration protection. The submitted test documents should correspond to the exact configuration that will be delivered.

Three sandwich-panel core materials are listed for this product. EPS is described as a cost-conscious option that provides effective thermal insulation. Rock wool is described as fireproof and capable of delivering high fire resistance. PU polyurethane is identified by its very low thermal conductivity and strong insulating performance. Since the available product information does not provide a numerical fire-resistance period or a formal fire classification for these materials, the buyer should request verified results rather than assume a specific rating.

The folding container house is built around a hot-dip galvanized steel frame, with Q355 high-strength steel specified for export models. The structure is assembled with bolts and does not require welding at the installation site. Its listed corrosion-protection process includes pickling, phosphating, and electrostatic powder coating, with a coating thickness of at least 60 micrometers. These specifications support durability and corrosion resistance, but they should not be interpreted as proof of a fire-resistance classification.

The walls and roof use double-sided color-coated galvanized steel sheets with a stated thickness of 0.4–0.5 mm. Panel widths are available in 950 mm and 980 mm. The floor includes a galvanized square-tube support grid and an 18 mm cement-fiber board or MGO board, while PVC floor leather or anti-slip ceramic tile can be used as the finished surface. Request fire data for every selected layer, particularly at the junctions between the floor, walls, roof, interior finishes, and service openings.

Electrical Systems, Certification, and Intended Use

The unit is supplied with a pre-installed electrical package that may include LED ceiling lights, power outlets, a distribution box, and conduits concealed within the wall panels. Hidden wiring and penetrations can influence fire behavior, so the purchase documents should identify the cable type, protective devices, conduit arrangement, penetration seals, and destination-market compliance evidence. Although the product data states compliance with electrical standards in Southeast Asia, North America, and South America, it does not specify a numerical fire classification for the building.

Guangdong Uni-House Technology Co., Ltd. provides a CE certificate identified as No. 3N240819.GUTQO66. The certificate is listed for the EU, Australia, North America, South America, Southeast Asia, and the Middle East, and relates to modular container house products such as folding and expandable containers. Buyers should inspect the certificate’s exact scope and model coverage. A CE certificate should not replace a project-specific fire test or a documented fire classification for the selected space capsule house.

One reported project for an Indonesian energy company used folding or modular units as dormitories for mining workers. The supplier also reports experience in engineering, infrastructure, cultural and tourism projects, livelihood programs, and private-owner applications. Because these occupancies have different risks, the required fire performance depends on the number of occupants, site conditions, local approval process, climate, escape routes, and final interior arrangement.

Frequently Asked Questions

Is rock wool the best choice for a fire-conscious buyer?

Rock wool is the panel option specifically described in the available data as fireproof and highly fire resistant. It is therefore the most appropriate material to request when fire performance is important. However, the material description alone is insufficient. Ask for a test report or classification covering the complete wall and roof assembly, including the joints and penetrations.

Can a CE certificate confirm the fire rating?

No. The supplied CE certificate is associated with modular container house products and lists several geographical markets, but the available information does not show a numerical fire-resistance period for the chosen space capsule model. Review the certificate scope and request separate fire-performance documentation for the exact product configuration.

What should be written into the purchase contract?

Record the panel core, panel thickness, steel surfaces, roof and floor construction, doors and windows, electrical system, joint design, penetration treatment, applicable local standards, fire-test reports, inspection requirements, warranty terms, and the final approved material schedule. This prevents a documented option from being replaced by a different configuration during production.

Conclusion

The correct fire rating to request is a documented classification for the complete space capsule house assembly, assessed under the building standard applicable at the destination. Specify rock wool panels when higher fire resistance is required, but do not treat the product name, steel frame, or CE certificate as proof of a numerical rating. Confirm electrical requirements, review the exact test evidence, and attach the approved configuration to the contract.
