Thermal and Sound Insulation Treatment for Container Houses

The thermal and sound insulation treatment of container houses requires comprehensive optimization from three aspects: material selection, structural design, and construction techniques. The specific measures are as follows:

I. Thermal Insulation Treatment

1. Wall and Roof Insulation Layers
   High-density insulation materials (such as rock wool, polyurethane foam layers, or polystyrene foam) should be used, with a thickness of at least 50mm and a thermal conductivity of no more than 0.04W/(m·K). For example, a regular cultural and tourism space capsule is internally filled with 75mm-thick rock wool, combined with thermal break insulation technology, effectively blocking heat and cold conduction. The outer layer is recommended to use anti-corrosion color-coated steel plates to reflect sunlight, while the inner layer uses fire-resistant gypsum boards + moisture-proof films to synergistically control temperature, forming a three-layer structure of 'reflection-blocking-stable temperature'.

2. Window and Door System Optimization
   Choose thermal break aluminum double-glazed windows (such as triple-glazed windows) with a heat transfer coefficient of no more than 0.45W/(㎡·K), providing better thermal insulation performance than traditional red brick walls. In summer, it can reduce the cabin's temperature rise time by 22 minutes, and in winter, the indoor temperature only drops by 1.3℃ after being closed for 8 hours.

3. Ventilation and Shading Design
   Install adjustable shading canopies, bottom ventilation slots, or roof eaves to prevent direct sunlight and heat accumulation. For example, a café in Moganshan uses aluminum foil reflective sandwich panels combined with shading design, allowing the cabin to remain comfortable without air conditioning even under direct afternoon sunlight.

II. Sound Insulation Treatment

1. Wall and Ceiling Sound Insulation Layers
   Add sound insulation and shock absorption sealing layers (such as glass wool, rubber sound insulation pads) in the walls and ceilings to block external wind and human noise. High-quality space capsules use multi-layer composite structures to achieve an indoor-outdoor noise difference of at least 35 decibels, meeting the needs of homestays and shops.

2. Enhanced Sealing Techniques
   Use triple-layer sealing strips at door frames, window frames, and wall panel joints, and apply weather-resistant sealant to all gaps to prevent sound transmission through gaps. For example, regular products require no leakage inside the wall panels after continuous water spraying for 72 hours, while ensuring airtightness standards are met.

3. Structural Shock Absorption Design
   The main frame's structural steel should have a thickness of at least 2.0mm, and the spacing between bottom load-bearing joists should be no more than 400mm to reduce noise generated by vibrations. Avoid using recycled steel or low-quality insulation cotton to prevent structural deformation and abnormal noises.

III. Key Construction Points

1. Material Quality Control
   Choose manufacturers with complete production qualifications to ensure that insulation rock wool, sound insulation layers, and other materials meet performance standards (such as thermal conductivity, noise difference). Avoid purchasing low-priced products from unqualified workshops, as their actual service life may be less than 3 years.

2. Joint and Drainage Treatment
   Seal panel joints, window and door closures, and roof splices with waterproof membranes + sealant, design a reasonable drainage slope (such as ≥2%), and ensure continuous water-shedding overlaps on the panels. In rainy southern regions, strengthen the waterproofing techniques for roofs and corners.

3. Long-term Maintenance
   Replace window and door sealant every 5-7 years, clean roof leaves annually to prevent water accumulation and corrosion of steel plates. Regularly check for wall condensation and balance temperature differences through internal insulation layers to avoid condensation dripping.

Through the above measures, container houses can achieve a 'warm in winter and cool in summer, quiet and undisturbed' living experience, while meeting the long-term use needs of cultural and tourism attractions, commercial streets, and other scenarios.
