Renovation of Old Prefabricated Panel Houses

The renovation of old prefabricated panel houses can be approached from three aspects: understanding the current situation, upgrading functions, and renovating the exterior facade.

Understanding the Current Situation

Due to their long construction history, old prefabricated panel houses may have numerous safety hazards, so a comprehensive inspection must be carried out before renovation. Hire a professional team and a qualified inspection agency to conduct a thorough 'physical examination' of the house using professional instruments. Focus on checking for cracks in the walls. If the cracks are minor, grout injection can be used to fill the gaps by injecting repair materials into the cracks, enhancing the stability of the walls. If the cracks are severe, steel plate reinforcement is required to improve the load-bearing capacity of the walls through the support of the steel plates. At the same time, check for rust on the steel bars, as rusty steel bars can affect the structural safety of the house. If rust is found, derusting treatment is needed, and protective measures should be taken to prevent further rusting. Additionally, check for foundation settlement, as an unstable foundation can lead to house tilting and cracking. If the foundation is unstable, pile driving reinforcement may be necessary to increase the load-bearing capacity of the foundation and ensure the stability of the house. Based on the inspection results, a detailed 'treatment plan' should be formulated to provide a scientific basis for subsequent renovation work.

Upgrading Functions

• Sound Insulation: The walls of old houses are usually thin, resulting in poor sound insulation and affecting living comfort. Soundproof panels and double-glazed windows can be used to improve sound insulation. Soundproof panels have good sound insulation properties and can effectively block sound transmission. Double-glazed windows have an air layer in the middle, which also provides good sound insulation. After using soundproof panels and double-glazed windows, the sound insulation effect can be improved by about 70%, creating a quiet living environment for residents.
• Space: The spatial layout of prefabricated panel houses may be unreasonable. The layout can be changed by methods such as wall-to-beam conversion to expand the interior space. For example, convert the load-bearing walls of a two-story prefabricated panel house into beams to transform it into a workshop. Convert the first floor into a frame structure and open up the entire first-floor space to increase the sense of openness and usable area, meeting different living needs.

Renovating the Exterior Facade

The exterior facade is the 'face' of the house, and renovating it can enhance the overall aesthetics of the house. You can refer to the renovation cases of old houses in rural areas of Banan and redesign and renovate the exterior facade, such as repainting the walls and replacing the exterior wall materials. At the same time, installing new doors and windows can not only improve the airtightness and thermal insulation of the house but also make the appearance of the house more beautiful and elegant, giving the old house a new look.
