FAQs：
Q1：Is it hot inside a container house?
Conventional container homes can get hot, but WELLCAMP container homes solve this problem through professional design and specialized materials, achieving cool summers and warm winters.
- Filling material: Rock wool or glass wool is used as the core material in sandwich panels, providing excellent heat absorption and insulation to maintain a comfortable indoor temperature.
- Exterior wall color: White exterior steel panels can reduce surface temperature by more than 15°C compared to black or dark blue walls under the same sunlight.
- House design: For high-temperature regions, WELLCAMP adopts opposite door and window layouts for cross ventilation, with optional louver and sunshade solutions.
- Other options: Spray foam insulation inside the container home to seal gaps for superior thermal performance; use aluminum foil to reflect radiant heat.
Q2：Who is the largest manufacturer of prefab homes?
Q3：Is a container house safe?
From a structural mechanics perspective, container homes outperform traditional brick-concrete structures in many extreme environments.
- Wind and seismic resistance: Bolted connections and sandwich panel walls dissipate force through deformation with excellent cushioning. Wind resistance reaches Grade 10, seismic resistance Grade 8, far safer than traditional concrete houses. They are among the safest shelters in earthquake-prone regions such as Indonesia and Chile.
- Fire resistance and high temperature tolerance: Grade A non-combustible rock wool can be used as the sandwich core material. In the event of an internal fire, walls will not ignite or produce toxic fumes, providing ample escape time — ideal for high-temperature regions such as the Middle Eastern deserts.
- Lightning and electric shock resistance: The enclosed galvanized steel structure, based on the Faraday Cage Effect, quickly conducts current underground with a proper grounding system without damaging interior components.
- Zero formaldehyde and zero pollution: Bolted connections reduce extensive adhesive use, with no waste or dust during installation, minimizing health impacts.
Q4：How much would it cost to build a prefab?
In the prefab homes industry, cost varies greatly, depending mainly on whether you choose temporary/semi-permanent camp accommodation or permanent fully furnished residential buildings.
- 1. Core Unit Factory Price
Basic Model (WELLCAMP standard container house): $4,000 – $7,000Features: Standard 20ft size, galvanized steel frame, fireproof rock wool wall panels.Application: Site office, worker camp, temporary dormitory.
Upgraded Model (Apple Cabin / Expandable Unit): $15,000 – $35,000Features: Floor-to-ceiling glass, integrated bathroom, smart electrical system, modern stylish appearance.Application: Airbnb homestay, high-end vacation house.
Permanent Modular House (Light / Heavy Steel Structure): $60,000 – $150,000+Features: Multi-room layout, optional two-story structure, fully compliant with permanent residential building standards.
- 2. Hidden Cost Breakdown (Accounting for 30%-50% of Total Budget)
Purchasing the unit is only the first step. Completion requires additional investment as below:
Foundation Work: $2,000 – $8,000Cost depends on simple concrete pier foundation or full slab foundation.
Logistics & Lifting: $1,500 – $5,000Ocean freight is relatively stable. One 40HQ container can load 8–12 standard container units with great cost efficiency. Inland transport from port to site and crane rental should be budgeted in advance.
Plumbing & Electrical Installation: $3,000 – $7,000Includes septic tank connection, external main power connection, and on-site assembly labor cost.

Key Buying Tips：
Benefit from bulk purchaseIf you source products from suppliers with mature export systems like WELLCAMP, try to purchase 8–12 units in one order. The freight cost for a 40HQ container is fixed; shipping fully loaded units can cut the average transport cost by up to 6 times compared to shipping only one unit.
Factory prefabrication level is criticalComplete bathroom, flooring and electrical integration as much as possible in the factory. Every extra hour of on-site labor, especially in Europe and America, will greatly increase your budget.
Focus on whole-life cycle costLow-cost products usually reduce galvanized layer thickness and simplify drainage details. Although premium built-in drainage systems (such as WELLCAMP patented design) have a slightly higher initial price, they can save huge maintenance costs from water leakage over the next 20 years.
Q5：What are the disadvantages of a container home?
- 1. Disadvantage: Drum-like noise in rainy days
Pain point: Traditional container houses only adopt a single thin color-coated steel sheet for the roof. When heavy rain falls, the indoor noise level reaches 70-80 decibels, seriously affecting daily rest.
WELLCAMP Solution:Multi-layer roof system: We adopt a composite sandwich structure consisting of roof sheet + high-density rock wool + ceiling buckle panel.Upgraded noise reduction: A sound insulation and shock absorption layer is built into the roof structure, which effectively weakens the impact energy of raindrops. The indoor noise is reduced to 40-50 decibels, equivalent to the volume of daily indoor conversation.
- 2. Disadvantage: Water leakage risk at panel joints
Pain point: Ordinary container houses rely on manual caulking for waterproofing. After 3-5 years of aging, the sealant easily cracks, causing water leakage from roof corners and panel gaps.
WELLCAMP Solution:Large-slope water diversion system: Our top beam is equipped with embedded oversized water grooves, with rainwater drained through internal downpipes inside columns to guide the water flow scientifically.Full-coverage cover plate process: Special aluminum alloy buckle strips and customized waterproof seals are installed at the joints of wall panels and frames, reducing dependence on sealant and realizing structural waterproofing.
- 3. Disadvantage: Thermal bridging effect & corner condensation (mold growth)
Pain point: Steel features high thermal conductivity. In winter, warm indoor air contacts cold steel beams and generates condensed water, resulting in moldy corners and peeling wallpaper.
WELLCAMP Solution:Thermal break technology treatment: PE insulation sealing strips are added between the steel frame and interior panels to block the heat conduction path.High-standard core material: High-density fireproof rock wool or PU edge-sealed boards are adopted to greatly improve the overall R-Value and keep the interior permanently dry.
- 4. Disadvantage: Structural shaking & insufficient wind resistance safety
Pain point: Many low-cost container houses use steel with insufficient thickness (only 1.8mm-2.0mm), causing obvious shaking in strong winds.
WELLCAMP Solution:Heavy-duty steel frame: WELLCAMP standard frames adopt 2.3mm high-strength galvanized steel for higher overall structural stability.Professional connecting parts: All corner fittings and bolt connections have passed mechanical performance tests. Matched with the foundation anchoring solution, the house can resist Grade 10-12 strong winds.
- 5. Disadvantage: Cramped space & aesthetic monotony
Pain point: Traditional container houses have a strong temporary shed style, with low indoor height and a monotonous identical appearance.
WELLCAMP Solution:Customized floor height: We provide customized height of 2.7m or above, and support the design of large-area floor-to-ceiling glass curtain walls.Diversified exterior finishes: Optional exterior cladding with cement fiber boards, wood grain decorative panels, or special-shaped Apple Cabin design, completely getting rid of the traditional "iron box" image.
