Sound Insulation of Container Houses
Container houses can achieve good sound insulation through various methods:
Sound Insulation Treatment for Walls and Ceilings
Ordinary iron-sheet containers have poor sound insulation, allowing external wind and human voices to easily penetrate indoors. High-quality container houses incorporate sound-insulating, shock-absorbing, and sealing layers on walls and ceilings, such as filling with high-density thermal insulation rock wool. This material not only provides thermal insulation but also effectively blocks sound transmission, isolating external noise to meet the requirements of quiet environments for homestays, teahouses, shops, and other settings.
Sound Insulation Optimization for Doors and Windows
Doors and windows are significant channels for sound transmission, and simple container doors and windows have poor sound insulation performance. Container houses produced by reputable manufacturers use thermal-break aluminum double-glazed windows and doors. This structure effectively reduces sound transmission, improving the indoor acoustic environment while also providing thermal insulation and enhancing the overall comfort of the house.
Strengthening Sealing Techniques
Sound leakage can easily occur at the seams of container house panels and around door and window frames. Proper techniques involve using waterproof membranes and sealing with adhesive at these locations to ensure seamless sealing without breaks. Additionally, three layers of sealing strips are installed at door frames, window frames, and wall panel joints, and weather-resistant sealant is applied to all joint seams to further enhance the house's sealing and reduce sound transmission in and out.
Selection of Overall Structure and Materials
Choosing materials with good sound insulation properties and a reasonable structure is also crucial. For example, using a thickened container body, with main frame steel sections no less than 2.0mm thick, wall panels no less than 50mm thick, and bottom load-bearing joists spaced no more than 400mm apart, creates a more stable structure. This reduces noise generated by vibrations and, to a certain extent, blocks the transmission of external sounds.
