The Renovation of Prefabricated Panel Houses Built in the 1980s

The renovation of prefabricated panel houses built in the 1980s can start from aspects such as structural reinforcement, wall renovation, floor renovation, roof reinforcement, and window replacement, while also paying attention to matters such as wall, water and electricity circuit, and door and window inspections.

• Structural Reinforcement: Due to the long construction time of prefabricated panel houses, their structural stability may decline. Columns can be installed inside the house to support the main beams, reinforce the foundation of the house, enhance the overall stability of the building, and ensure living safety.
• Wall Renovation: The original walls may have problems such as poor thermal insulation and waterproofing performance. The walls can be re-treated with thermal insulation and waterproofing materials to improve the thermal insulation and waterproofing capabilities of the house; or wallpaper can be applied to improve the indoor visual effect.
• Floor Renovation: The floor materials of old houses may have been worn and aged. The original floor can be knocked out and laid with new materials, such as floor tiles, which are wear-resistant and easy to clean; or wooden floors can be chosen to give a warm and comfortable feeling.
• Roof Reinforcement: After being exposed to wind, sun, rain, and snow for a long time, the roof may be damaged. The roof can be reinforced again, for example, by replacing the tiles with color-coated steel tiles, which have the advantages of light weight, high strength, and good waterproofing performance.
• Window Replacement: The sealing and sound insulation performance of the windows in old houses may be poor. All the windows can be replaced with soundproof windows made of broken-bridge aluminum, which can effectively isolate external noise and improve living comfort.

Renovation Precautions:

• Do Not Randomly Demolish Walls: Even non-load-bearing walls should not be randomly demolished or modified. They are secondary load-bearing components and play an extremely important supporting role for load-bearing walls. Random demolition or modification may affect the structural safety of the house.
• Water and Electricity Circuit Renovation: Water and electricity circuits are related to home safety and should be carefully inspected and rectified according to different situations. The original water pipeline layout in old houses may be unreasonable, and there may be problems such as rust and aging. If the original pipelines use galvanized pipes that have been phased out, they must be completely replaced with copper pipes, aluminum-plastic composite pipes, or PP-R pipes.
• Door and Window Inspection: The hidden dangers of doors and windows are not easily visible to the naked eye and need to be inspected by a professional renovation team before making a decision. If the material is sturdy and the style is liked, it can be repainted; if wooden doors and windows are peeling or deformed, and the wood properties have changed, they must be replaced; if the paint film on the surface of steel doors and windows falls off, corresponding treatment is also required.
