How to Decorate Prefabricated Roof Panels of a House

The decoration of prefabricated roof panels of a house should be comprehensively planned based on flatness, functional requirements, and structural safety. The specific methods are as follows:

1. Flatness Treatment

The flatness of the prefabricated roof directly affects the choice of decoration methods:

• Small errors (gaps < 5 mm): Plastering can be used directly for leveling, with a cost of approximately 30 yuan per square meter. Note that the thickness of the plaster layer should not exceed 3 mm; otherwise, it may easily lead to hollowing or peeling due to shrinkage.
• Medium errors (5-20 mm): Plastering or gypsum leveling cannot meet the requirements, and a suspended ceiling is needed to cover the uneven areas.
• Large errors (> 20 mm): A suspended ceiling solution must be adopted to avoid material detachment or increased structural load caused by forced leveling.

2. Optimization of Hidden Wiring Layout

Prefabricated panels have hollow pipes running through them internally, which can be utilized for hidden wiring layout:

• Thread the sheathed wires through the hollow pipes of the prefabricated panels to avoid cutting grooves in the ceiling, which could compromise structural stability.
• If new wiring is required, plan the routing in advance to ensure smooth connection with the existing pipes and minimize secondary damage to the prefabricated panels.

3. Sound Insulation and Functional Upgrades

Poor sound insulation is a common issue in prefabricated panel houses and can be improved through the following methods:

• Professional soundproof suspended ceiling: Choose soundproof suspended ceiling systems from brands like Jason to fully cover the ceiling and effectively block noise from upstairs.
• Clip-in keel suspended ceiling: If ceiling height is limited, a clip-in keel suspended ceiling system can be used, with a thickness that can be controlled within a low range. It also supports a "lighting without a main fixture" design, achieving uniform illumination through recessed lighting fixtures.

4. Key Considerations

• Structural safety: Do not arbitrarily remove or modify the load-bearing structure of the prefabricated panels. If layout adjustments are needed, consult a professional architect or structural engineer.
• Water and electricity renovation: The water and electricity systems in prefabricated panel houses may be aged. During renovation, thoroughly replace the old pipelines to ensure electrical and water safety.
• Waterproofing: Focus on waterproofing in wet areas such as kitchens and bathrooms. It is recommended to apply flexible waterproof coatings twice and conduct a closed-water test to verify the effect.
• Energy-saving and thermal insulation: Adding thermal insulation materials (such as polystyrene boards) to the walls and roof can improve indoor temperature stability and reduce energy consumption.

Summary: The decoration of prefabricated roof panels should prioritize structural safety and select solutions based on flatness, sound insulation, water and electricity requirements, etc. Non-destructive techniques such as suspended ceilings and hidden wiring through pipes should be preferred, while also paying attention to waterproofing and thermal insulation to enhance living comfort.
