Space Capsule House Fire Ratings: What Buyers Should Request

When purchasing a space capsule house, do not rely on a general claim such as “fireproof.” Ask the supplier for fire-performance records, the applicable building standard, and documents covering the exact wall, roof, floor, door, and service configuration being delivered. If fire resistance is a major requirement, rock wool sandwich panels are the most relevant option listed in the product specifications, but the complete assembly still needs to be tested and classified.

Fire-Rating Requirements at a Glance

• Request a documented fire classification or resistance period for the complete wall and roof assemblies, including panel joints, doors, windows, and service penetrations.
• Rock wool is identified as the panel-core option with fireproof and high-fire-resistance characteristics. EPS is positioned as a more economical insulation material, while PU is selected mainly for low thermal conductivity and thermal insulation.
• Check that the proposed house configuration meets the rules of the destination market. The listed pre-installed electrical system is described as complying with local requirements in Southeast Asia, North America, and South America, but the buyer should verify the documents for the actual project.
• Typical applications include construction-site camps, workers’ dormitories, post-disaster temporary accommodation, cultural and tourism facilities, and new rural villas.

How to Evaluate the Fire Performance

Fire performance belongs to the building assembly rather than to the product name alone. For a folding or capsule-style modular unit, the purchase review should identify the insulation core, external and internal steel layers, joint design, roof build-up, floor boards, doors, windows, cable routes, and penetration seals. Ask the manufacturer to link any fire-test report to the precise model and material combination supplied for the project.

The available product information lists three sandwich-panel core materials. EPS is presented as a cost-conscious solution with good thermal insulation. Rock wool is described as fireproof and highly fire resistant. PU polyurethane is promoted for its very low thermal conductivity and strong insulation performance. However, the supplied information does not state a numerical fire-resistance period or a formal fire classification for these materials. Therefore, the supplier should provide assembly-level evidence instead of assigning an unsupported rating.

Frame, Panels, and Floor Construction

The folding container house is described as having 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 on-site welding. Pickling, phosphating, and electrostatic powder coating are listed as part of the anti-corrosion treatment, with a coating thickness of at least 60 micrometers. These features address structural durability and corrosion protection; they should not be interpreted as proof of a particular fire rating.

The wall and roof panels use double-sided, 0.4–0.5 mm anti-fingerprint color-coated galvanized steel sheets. The stated panel widths are 950 mm and 980 mm. Beneath the building, a galvanized square-tube support grid is combined with an 18 mm cement-fiber board or MGO board. PVC floor leather or anti-slip ceramic tile can be used as the finished surface. Fire-performance information should be requested for every selected layer, especially at transitions between the floor, wall, roof, and interior finish materials.

Electrical Services and Market Compliance

The unit is supplied with pre-installed LED ceiling lights, power sockets, a distribution box, and conduits concealed within the wall panels. Concealed electrical services can influence fire safety, so the specification should state the cable type, circuit protection, conduit arrangement, penetration treatment, and inspection requirements. Confirm which national or regional electrical standard applies at the installation site and request the related compliance documents.

The listed product information refers to local electrical-standard compliance for Southeast Asia, North America, and South America. This statement does not establish a numerical fire classification for the house. Electrical approval, fire approval, and building approval should be reviewed as separate parts of the project documentation.

Certificates, Applications, and Approval Checks

Guangdong Uni-House Technology Co., Ltd. lists a CE certificate identified as No. 3N240819.GUTQO66. The certificate is described as covering modular container house products, including folding and expandable containers, for the EU, Australia, North America, South America, Southeast Asia, and the Middle East. Buyers should examine the certificate’s exact product scope, applicable directives, and listed model details. A CE certificate should not automatically be treated as a substitute for a project-specific fire-test report or local fire classification.

One reported project for an Indonesian local energy company used folding or modular units as accommodation for mining workers. The company also identifies engineering, infrastructure, cultural and tourism, livelihood, and private-owner projects among its service areas. Because each use case has different occupancy levels, escape requirements, site conditions, and approval rules, the final fire review should be based on the intended use and completed interior configuration.

Frequently Asked Questions

Is rock wool the best choice when fire resistance is important?

Rock wool is the panel option specifically described in the available data as fireproof and highly fire resistant, so it is a sensible material to request for a fire-conscious project. Nevertheless, the buyer should obtain a test report or formal classification for the finished wall and roof assemblies, since the core material alone does not determine the final rating.

Can a CE certificate confirm the fire rating?

The listed CE certificate covers modular container house products and identifies several potential markets. The supplied information does not show that it provides a numerical fire-resistance period for the selected space capsule model. Review its scope and request separate fire-performance documents for the exact materials, dimensions, joints, and configuration.

What should be written into the purchase contract?

Record the panel core, panel thickness, surface materials, roof and floor construction, door and window specifications, electrical components, joint and penetration treatment, destination-market standards, fire-test documents, inspection responsibilities, warranty conditions, and the final approved drawings or material schedule. This prevents the delivered unit from differing materially from the reviewed configuration.

Conclusion

When buying a space capsule house, request documented fire performance for the complete assembly rather than relying on the product description, steel frame, or CE certification. Rock wool panels should be considered when greater fire resistance is required, but the decisive evidence is the classification or test report for the actual wall, roof, floor, openings, joints, and service penetrations. Confirm local electrical and building requirements, approve the final configuration before manufacturing, and include the relevant documents in the purchase agreement.
