Prefabricated House Decoration Advice

Admin September 18, 2026

When decorating a prefabricated house, it is necessary to comprehensively consider structural safety, functional optimization, and living experience. Here are specific suggestions:

1. Prioritize Structural Safety

  • Professional Assessment: Before decoration, entrust a structural engineer to conduct a comprehensive inspection of the prefabricated panel house, clarify the positions of key structures such as load-bearing walls, beams, and columns, and avoid damaging the overall stability due to renovation.
  • Lightweight Materials: The load-bearing capacity of prefabricated panels is limited. During decoration, lightweight and high-strength materials should be preferred. For example, reduce the use of suspended ceilings. If installation is required, lightweight materials such as gypsum boards and aluminum扣板 (aluminum ceiling tiles) should be selected, and avoid using expansion screws on prefabricated panels; instead, use wooden plugs for fixation. For wall decoration, avoid using stones and heavy tiles, and recommend lightweight materials such as latex paint and wall coverings.

2. Waterproofing and Circuit Renovation

  • Waterproofing Treatment: Thorough waterproofing is required in water-using areas such as bathrooms and kitchens. The height of the ground waterproof layer should be no less than 30 centimeters, and the wall waterproof layer should extend to more than 1.8 meters. After construction, conduct a 48-hour closed-water test to confirm no leakage before laying floor tiles.
  • Circuit Upgrade: The circuits in old prefabricated houses may have problems such as aging and unreasonable layout. It is necessary to re-plan the circuits, increase the number of sockets (especially in power-intensive areas such as kitchens and living rooms), and select copper-core wires that comply with current standards to ensure electrical safety.

3. Ventilation, Lighting, and Sound Insulation Optimization

  • Ventilation Improvement: Improve indoor air circulation efficiency by enlarging window sizes, adding exhaust fans or fresh air systems, and reduce moisture and odors.
  • Lighting Enhancement: Removing non-load-bearing partitions and using light-colored walls and reflective materials (such as mirrors and glass) can effectively increase indoor brightness.
  • Sound Insulation and Thermal Insulation: Houses in northern regions need to strengthen the wall thermal insulation layer (such as attaching polystyrene boards externally), and replace windows with double-glazed units and seal them with weatherstripping; houses in southern regions can add sound insulation cotton or acoustic panels to reduce external noise interference.

4. Space and Style Design

  • Space Utilization: Small apartments can adopt multi-functional furniture (such as sofa beds and folding tables) and custom-built embedded storage cabinets to maximize the use of vertical space; avoid large and bulky furniture and keep corridors clear.
  • Style Selection: Determine the style according to living needs. The simple and modern style is suitable for small spaces (reducing decorative lines), and the retro and nostalgic style can create a warm atmosphere through wooden furniture and warm-toned lighting, but it is necessary to ensure a balance between style and function.

5. Environmental Protection and Budget Control

  • Environmentally Friendly Materials: Select environmentally friendly building materials such as low-formaldehyde panels and water-based paints. After decoration, keep the ventilation for 3-6 months and place activated carbon and green plants to assist in purifying the air.
  • Budget Planning: Prepare a detailed budget sheet in advance, distinguish between hard decoration (water and electricity, walls) and soft decoration (furniture, decorations) costs, prioritize ensuring structural safety and basic functions, and avoid overspending.

6. Material Selection Details

  • Flooring Materials: Wooden floors or floor tiles are recommended for living rooms and bedrooms. Avoid using heavy materials such as marble and granite to reduce the load on the floor.
  • Wall Materials: Be cautious when using wallpaper glue (which may contain formaldehyde) and prefer environmentally friendly latex paint or diatomaceous earth.
