The performance advantages of capsule houses stem from their scientific structural design and high-quality material combinations. The overall structure progresses layer by layer from the outside to the inside, taking into account the needs of protection, heat preservation, sound insulation, and practicality. Specifically, it can be divided into three major layers: "external structure, intermediate protection, and internal function":
(I) External Structural Layer: Strong Protection + High Aesthetics, Adaptable to Diverse Environments
The external structure is the "protective barrier" of the capsule house, and also determines its appearance. Its core consists of "main frame, exterior panels, and door and window system":
1. Main Frame: The core load-bearing component, generally using two materials: one is a galvanized square steel frame, which is cost-effective and has strong rust resistance. After pickling and galvanizing, it can resist corrosion from the humid salt spray of the seaside and the humid environment of the countryside, with a service life of over 20 years; the other is an aluminum alloy frame, which is lighter (30%-40% lighter than steel structures of the same strength), has lower transportation costs, and has better oxidation and corrosion resistance, with a service life of over 30 years, suitable for long-term outdoor use scenarios (such as cultural tourism homestays and outdoor campsites). Frame spacing is typically controlled at 50-80cm to ensure structural stability while reserving space for pipeline and appliance installation.
2. Exterior Panels: Balancing aesthetics and protection, three main material choices are chosen: ① Fluorocarbon aluminum panels: Extremely weather-resistant, able to withstand UV exposure and rain, not easily fading or deforming, and available in a variety of colors (customizable white, gray, dark brown, etc.). Surface finishes can be frosted or mirrored, offering a high-tech feel, making it the preferred choice for high-end space capsules; ② Metal carved panels: Cost-effective, composed of color steel plates + polyurethane foam + back panel, combining decorative and insulating properties. Surface finishes include wood grain and stone textures, suitable for rural and pastoral settings; ③ Fiberglass: High strength and toughness, allowing for complex streamlined shapes. Lightweight and with excellent waterproof properties, suitable for humid environments such as beaches and lakesides, but prone to aging under prolonged sun exposure, requiring regular maintenance.
3. Door and Window System: The core functionality addresses the needs for "sealing, heat insulation, and soundproofing," employing a combination of thermally broken aluminum profiles and double-glazed Low-E glass. The thermally broken aluminum profiles block heat transfer, reducing energy consumption caused by indoor-outdoor temperature differences (insulating in winter and providing heat insulation in summer). The double-glazed Low-E glass has a low-emissivity film on the inner layer, reflecting infrared rays to further enhance insulation. It also offers excellent sound insulation (blocking over 60% of external noise). Some high-end models are equipped with motorized panoramic floor-to-ceiling windows, combining natural light and views, catering to the needs of tourism and accommodation scenarios. The doors and windows are sealed with EPDM rubber strips, which are waterproof, windproof, and wear-resistant, preventing rainwater leakage and cold air intrusion.
(II) Intermediate Protective Layer: Thermal Insulation + Sound Insulation + Waterproofing for Comfortable Living
The intermediate protective layer is the core support for the "comfortable living" of the space capsule house. Located between the main frame and the interior panels, it is composed of multiple layers of functional materials, covering the three core requirements of thermal insulation, sound insulation, and waterproofing:
1. Thermal Insulation Layer: Mainstream use is polyurethane rigid foam filling, with a low thermal conductivity (below 0.024W/(m・K), far superior to traditional rock wool and polystyrene boards), providing excellent thermal insulation performance and meeting the living needs in extreme environments from -30℃ to 40℃ (indoor temperature can be maintained above 18℃ in winter and below 25℃ in summer); some high-end space capsules additionally add extruded polystyrene boards for auxiliary insulation, further improving thermal insulation performance while reducing energy consumption.
2. Sound Insulation and Noise Reduction Layer: Divided into "Outdoor Sound Insulation" and "Indoor Sound Insulation"-Outdoor sound insulation is achieved through exterior panels and double-glazed windows, blocking external noise (such as wind, traffic noise, and crowd noise); indoor sound insulation involves adding sound-absorbing cotton and damping sheets to the floor, ceiling, and wall layers to reduce indoor echoes and appliance noise, while also preventing sound transmission when multiple compartments are joined, ensuring a quiet living environment (indoor noise can be controlled below 35 decibels, meeting quiet living standards).
3. Waterproof and Moisture-proof Layer: Employing a "multi-protection" design-First, the main frame joints are double-sealed with sealant and waterproof tape to prevent rainwater from seeping in through gaps; second, waterproof eaves are added to the bottom of the exterior panels to guide rainwater drainage and prevent water accumulation from eroding the underlying structure; third, waterproof membrane is laid in the floor layer to prevent ground moisture from rising, especially suitable for humid environments such as coastal areas and rural areas, preventing indoor mold and dampness.
(III) Internal Functional Layer: Compact and Practical, Adaptable to All Scenarios
The internal functional layer is laid out around "living needs." Although the area of a single cabin is mostly 15-30㎡ (mainstream 20-25㎡), through scientific planning, it can achieve full functional coverage of "bedroom + living room + kitchen and bathroom + storage," while also supporting personalized customization:
1. Flooring System: A choice between "non-slip floor tiles + solid wood flooring" is available-non-slip floor tiles are suitable for the kitchen and bathroom areas, being waterproof, wear-resistant, and easy to clean; solid wood flooring (or composite solid wood flooring) is suitable for the bedroom and living room areas, enhancing texture and comfort underfoot, with a moisture-proof mat and sound-insulating mat laid underneath for both moisture protection and sound insulation. 2. Walls and Ceilings: Walls primarily use bamboo-fiber integrated panels, which are environmentally friendly, formaldehyde-free (E0 standard), waterproof, moisture-proof, and easy to clean. The surface can be finished in solid colors or with a wood grain finish. Installation is convenient and replaceable. Ceilings feature integrated suspended ceilings with recessed lighting and fresh air vents, offering a clean and aesthetically pleasing design. Access panels are also provided for easy maintenance.
3. Kitchen and Bathroom Systems: All systems utilize a "prefabricated + built-in design," saving space and offering practicality. The kitchen is equipped with a mini integrated cooktop (combining stir-frying, cooking, and fume extraction), a sink, and small storage cabinets. Some models include a microwave and refrigerator to meet basic cooking needs. Bathrooms feature a wet and dry separation design, equipped with a complete bathroom unit (waterproof and leak-proof), a toilet (mainstream smart toilets for comfort), a shower, and a sink. Some high-end models include a space for a washing machine, suitable for long-term living.
4. Water and Electricity System: Adopting an "independent integration + safety protection" design – the electrical system is pre-installed with national standard copper wire, equipped with leakage protection devices and air switches to avoid the risk of leakage and short circuits, while reserving interfaces for smart home appliances and photovoltaic panels; the water system uses food-grade PPR pipes, equipped with water filters to ensure water safety, supports municipal water supply access, and can also be adapted to water tank storage (for outdoor scenarios); the drainage system uses sealed pipes and connects to the municipal pipe network or septic tank to prevent odor leakage.
