On May 28th, the State Council officially issued the "15th Five Year Plan for Urban Renewal", which clarifies the core principles of "retaining, renovating, and demolishing simultaneously, focusing on preservation, utilization, and upgrading, and resolutely preventing large-scale demolition and construction".
This marks the complete departure of China's urban construction from the "bulldozer style" large-scale demolition and construction, and the comprehensive entry into a new stage of stock improvement, fine renovation, and prioritizing people's livelihoods.
As the core livelihood project of urban renewal, the renovation of old areas, the upgrading of exterior wall doors and windows, is listed as a key task, and the selection of sealant is a key factor in determining the quality and long-term effectiveness of the renovation.
01 In depth interpretation | From "demolition and construction" to "retention and renovation"
The "15th Five Year Plan" for urban renewal is a special five-year plan for urban renewal in China, with a fundamental shift in its core logic:
✅ Say goodbye to large-scale demolition and construction: prohibit large-scale demolition, relocation, and logging, abandon extensive urban construction, and shift to a refined model that can be repaired but not demolished, and can be modified but not pushed forward.
✅ Focusing on improving existing quality: During the 15th Five Year Plan period, it is planned to start renovating 115000 old urban residential areas, with a focus on promoting the renovation of dilapidated houses, upgrading old residential areas, and updating urban villages. The core is to improve the quality of living and fill in the gaps in people's livelihoods.
✅ Livelihood priority orientation: With the goal of "good houses, good communities, good neighborhoods, and good urban areas", starting from the issues that residents are most concerned about, such as external wall insulation, door and window updates, waterproofing and anti-seepage, we aim to make old houses safer, more comfortable, and more energy-efficient.
In short, future urban renewal is no longer driven by the interests of "demolishing the old and replacing the new", but rather a livelihood project of "repairing the old, revitalizing the new, and upgrading the quality". The renovation of exterior walls, doors, and windows has become the core focus of policy implementation.
02 Key points of renovation | Upgrading exterior doors and windows
Old residential areas have been built for a long time, and there are four major pain points in the exterior walls, including aging and damage, sealing failure, excessive energy consumption, and safety hazards, which directly affect the quality of life of residents and the lifespan of buildings. Upgrading and renovation are urgently needed
1. Sealing failure, leakage and ventilation become stubborn problems: old door and window rubber strips age, window frames deform, and rainwater easily seeps into the wall; Cold and hot air circulate freely, with cold winters and hot summers, resulting in a very poor living experience.
2. The soaring energy consumption does not meet the requirements of green and low-carbon: the insulation performance of old doors and windows is poor. According to calculations, the additional heating/air conditioning costs per household for unrenovated old houses are seriously inconsistent with the national energy conservation and carbon reduction policies.
3. Prominent safety hazards pose a threat to residential safety: rusting of door and window hardware, ineffective locks, and weak anti-theft capabilities; Glass is aging and fragile, and there is a risk of falling from high-rise buildings; Long term water seepage from exterior walls can corrode the walls and easily lead to structural hazards.
4. The highest cost-effectiveness and the strongest sense of livelihood gain: The renovation of exterior doors and windows requires moderate investment and quick results, which can solve core pain points such as leakage, sound insulation, and thermal insulation. It is a visible and tangible livelihood project for residents.
Therefore, under the guidance of the "retention, renovation, and demolition" policy, upgrading the exterior wall doors and windows project has become a key and essential project for the renovation of old areas, and is the core measure to implement the "preservation, utilization, and improvement" policy.
03 Upgrade Core | Sealing glue is the "lifeline"
Many people think that upgrading doors and windows is just about replacing window frames and glass, but in fact, sealant is the core of the core:
✅ Waterproof barrier: The gaps between doors and windows and walls, as well as between window frames and glass, are the most vulnerable areas for leakage. High quality sealant can provide long-lasting waterproofing and anti-seepage, preventing rainwater from eroding walls.
✅ Energy saving key: The airtightness of sealant directly determines the insulation effect of doors and windows. High quality sealant can block the circulation of hot and cold air, reduce energy consumption, and achieve green energy conservation.
✅ Weathering Guardian: External doors and windows are exposed to extreme environments such as ultraviolet radiation, high temperatures, severe cold, and acid rain for a long time. C-558 has long-lasting flexibility, no cracking, and no detachment.
It can be said that upgrading doors and windows requires three parts to rely on window frames and seven parts to rely on sealing. By selecting the right weather resistant sealant, the transformation was more than half successful; Choosing the wrong adhesive not only causes repeated leakage, but also results in significant economic losses.
04 Genesis C-558 | The "all-in-one choice" for door and window renovation
Genesis C-558 multifunctional weather resistant sealant has become the preferred product for upgrading the sealing of doors and windows in old residential areas due to its four core advantages of "full substrate compatibility, super weather resistance, environmental protection and long-term effectiveness, and convenient construction".
✅ Neutral curing: using a single component neutral curing formula, without acidic corrosion, suitable for the renovation of various door and window materials in old residential areas.
✅ Super weather resistance: resistant to ultraviolet rays, ozone, acid rain, and extreme environments of high and low temperatures, maintaining flexibility and elasticity outdoors for a long time, avoiding cracking and peeling, and requiring one-time construction.
✅ Waterproof and anti-seepage: After curing, a highly elastic waterproof sealing layer is formed, with a waterproof level of the highest national standard, completely solving the problem of leakage in window frames and wall gaps.
✅ Environmentally friendly low VOC: Low VOC environmentally friendly formula, no harmful volatiles, no irritating odors, safe indoor and outdoor construction, in line with national green building materials standards.
05 Conclusion | Cities are moving towards the "15th Five Year Plan" era
In the era of urban renewal during the 15th Five Year Plan period, "retaining, renovating, and demolishing simultaneously, with preservation and improvement as the main focus" has become a foregone conclusion. The transformation of old areas has bid farewell to large-scale demolition and construction, and shifted towards refinement, quality, and livelihood upgrading. As the core of renovation, exterior wall doors and windows engineering requires sealant as the key to quality.
Genesis C-558 multifunctional weather resistant sealant, with its strong core strength of environmental protection, super weather resistance, long-term sealing, and convenient construction, perfectly adapts to the needs of exterior wall and door renovation in old residential areas. It builds three lines of defense for waterproofing, energy conservation, and weather resistance in old buildings, helps improve the quality and efficiency of urban renewal, revitalizes old houses, and makes residents' lives more comfortable and reassuring!
