Pre-engineered for extreme seasonal temperature differentials, fully compatible with South Korea’s Energy Saving Design Standards.
Daejeon Metropolitan City, situated in the central region of South Korea within the Geum River basin, presents unique thermodynamic challenges for prefabricated and containerized building structures. As South Korea's premier science and technology hub—home to Daedeok Innopolis, KAIST, and numerous state-backed R&D centers—the demand for rapid-deployment, high-efficiency modular space solutions has grown exponentially.
However, Daejeon experiences a humid continental climate featuring severe sub-zero Siberian winds in winter (temperatures dropping below -10°C) and scorching, highly humid East Asian monsoon summers (temperatures exceeding 35°C with relative humidity over 85%). Standard ISO shipping container modifications suffer from extreme thermal conductivity ($\lambda \approx 50 \text{ W/m}\cdot\text{K}$ for structural steel), leading to catastrophic thermal bridging, internal condensation (sweating), mold growth, and unsustainable HVAC power consumption if not paired with advanced insulation systems engineered for Korea Region 2/Central Region thermal metrics.
Our insulation manufacturing matrices are specifically tailored to surpass South Korean KBC (Korean Building Code) requirements.
Providing actionable information gain: Comparing material core structures, installation methodologies, and isotropic thermal bridging solutions for container units.
High-density Polyisocyanurate (PIR) foam injected continuous core systems offer a minimal thermal conductivity of 0.022 W/m·K. Engineered with zero-ODP blowing agents, PIR eliminates air gaps between the corrugated steel container skin and interior drywall, preventing convective heat loops and internal wall cavity moisture accumulation.
For space-constrained architectural builds in high-density urban areas like Daejeon's Yuseong District, Vacuum Insulation Panels (VIP) paired with Silica Aerogel blankets deliver an unprecedented thermal performance (R-value up to R-50 per inch). This ultra-thin profile saves up to 12% of interior usable floor area.
Exterior Insulation Finishing Systems (EIFS) wrap the container exterior in continuous Rockwool/EPS barrier boards. Thermal isolation strips (aerogel-gasketed stud shoes) break structural steel cold channels, completely isolating internal structural frames from outdoor temperature swings.
| Insulation Type | Thermal Conductivity ($\lambda$) | Moisture Resistance | Fire Rating (EN 13501-1) | Daejeon Suitability Index |
|---|---|---|---|---|
| High-Density PIR Sandwich Panel | 0.020 - 0.023 W/m·K | High (Closed-cell >95%) | B-s1, d0 (Flame Retardant) | 9.8 / 10 (Recommended) |
| Hydrophobic Rockwool / Mineral Wool | 0.034 - 0.040 W/m·K | Medium (Requires Vapor Barrier) | A1 Non-combustible | 9.2 / 10 (High Fire Safety) |
| Silica Aerogel Composite Blanket | 0.015 - 0.018 W/m·K | Ultra-High (Superhydrophobic) | A1 Non-combustible | 9.6 / 10 (Best Space-Saving) |
| Spray Polyurethane Foam (SPF - Open Cell) | 0.036 - 0.039 W/m·K | Low (Vapor Permeable) | Class B3 / Combustible | 6.1 / 10 (Not Recommended) |
Technical Insight: In Daejeon’s winter climate, moisture vapor drives from interior heated spaces outward toward the cold corrugated steel skin. Without a continuous interior smart vapor retarder (e.g., polyamide film with variable humidity resistance), interstitial condensation occurs behind traditional rockwool insulation, leading to structural corrosion and loss of insulation efficacy. Shanghai BYT Homes integrates dual-action hygrothermal barriers as standard manufacturing protocol.
Empowering commercial developers, scientific institutions, and hospitality investors with standardized quality assurance for large-scale container deployments.
Shanghai BYT Homes Co., Ltd. operates state-of-the-art manufacturing facilities equipped with automated sandwich panel continuous lamination lines, CNC structural framing stations, and robotized polyurethane injection cells. Every unit destined for export to South Korea undergoes rigorous structural stress testing and thermal imaging verification.
Shipping directly to the Port of Incheon or Port of Busan, followed by flat-bed trailer transit to Daejeon via the Gyeongbu Expressway corridor (Route 1). Our products fully align with South Korean import customs and localized civil code filings:
Aligning with South Korea’s mandatory Zero-Energy Building (ZEB) roadmap for public and commercial installations in Daejeon Smart City.
Integrating microencapsulated PCM into interior drywall assemblies. PCMs absorb latent heat during peak daytime summer solar radiation and release heat during freezing Daejeon winter nights, stabilizing indoor temperature variations without active HVAC input.
Embedded wireless micro-sensors located within insulation core layers monitor relative humidity, thermal migration, and structural strain in real-time. System telemetry interfaces directly with building management platforms via LoRaWAN or 5G networks.
Building-Integrated Photovoltaic (BIPV) roofing panels coupled with triple-glazed, aerogel-filled low-E window frames maximize solar power generation while maintaining ultra-low U-factors ($U \le 0.8 \text{ W/m}^2\text{K}$).
Integrated design, engineering, thermal processing, customization, sales, and global construction execution.
Shanghai BYT Homes Co., Ltd. is a comprehensive enterprise integrating design, production, processing, customization, sales, and construction. The company is located in Shanghai, China.

We firmly believe that every transaction marks the beginning of long-term cooperation, and our service never ends. We sincerely look forward to working with you to create a better future!
Technical clarity for structural engineers, procurement officers, and resort project developers.
We utilize structural continuous PIR core sandwich panels ($U \le 0.16 \text{ W/m}^2\text{K}$) combined with exterior thermal break gaskets. This continuous insulation envelope eliminates cold-bridge conduction through the steel skeleton, effortlessly meeting Korean Building Code (Central Region 2) requirements.
Our systems feature engineered vapor control membranes and closed-cell hydrophobic insulation materials (>95% closed cell content). By preventing moist air from coming into contact with cold steel structural elements, internal interstitial condensation is completely avoided.
Yes. Every container module is engineered using structural high-grade corrugated corten steel and reinforced cold-formed steel framing, rated for basic wind speeds up to 35 m/s and seismic loads corresponding to Korean Seismic Zone 1.
Standard manufacturing cycles take 15–20 days. Shipments dispatch from Shanghai Port to Incheon Port (approx. 2-3 days maritime transit) followed by immediate highway flatbed delivery directly to your project site in Daejeon.
Versatile, rapid-deployment modular options engineered for residential, commercial, eco-tourism, and industrial projects in Daejeon.
