Recently, the State Council officially approved the "15th Five-Year Plan for Expanding Consumption," clearly outlining key initiatives in the housing sector. These include implementing a housing quality improvement program, building safe, comfortable, green, and smart "quality homes," steadily advancing the renovation of dilapidated and aging urban residential buildings, and supporting age-friendly upgrades of older housing. These measures define the core direction for enhancing and expanding housing consumption and promoting green transformation in the construction industry during this new era.
As a leading technology enterprise in China's bio-based building materials sector, Anhui Beijia Green Building Materials Co., Ltd. has developed a series of polylactic acid-aerogel crystal insulation boards that precisely meet the housing development needs outlined in national planning. With high performance, low carbon footprint, and extended service life, these innovative green building materials offer comprehensive material solutions for high-quality residential construction, renovation of existing buildings, and upgrades to age-friendly environments—delivering "quality materials" to support the realization of "quality homes."
1. Targeting the "Quality Home" Vision: Strengthening the Foundation for Housing Quality Improvement
The "Fifteenth Five-Year Plan for Expanding Consumption" identifies the construction of "safe, comfortable, green, and smart 'quality homes'" as the core objective of housing quality enhancement projects. This aligns closely with the Ministry of Housing and Urban-Rural Development’s "Five Good" construction requirements—excellent standards, excellent design, excellent materials, excellent construction, and excellent services—with "excellent materials" forming the fundamental cornerstone of housing quality.
Centered on globally pioneering bio-mineral hybrid technology, the polylactic acid-aerogel crystal insulation board overcomes the traditional performance limitations of conventional insulation materials—where fire resistance and thermal insulation are difficult to balance, and lightweight properties conflict with strength. It meets the standards for "quality homes" across three key dimensions:
● Safety Dimension: Long-term stability, ensuring structural safety.
The product achieves Class A fire resistance, eliminating the risk of exterior wall insulation fires at the material source. With inorganic aerogel as the continuous phase, it offers excellent resistance to ultraviolet aging and structural stability verified over nearly 30 years in outdoor conditions, enabling a lifespan equivalent to that of the building itself, thus providing long-term safety assurance for building envelope systems.
● Comfort Dimension: Thermal insulation and water-repellent properties enhance living comfort.
The product has a thermal conductivity as low as 0.040 W/(m·K), placing it among the top inorganic insulation materials for heat preservation and thermal insulation, effectively maintaining stable indoor temperatures and reducing discomfort caused by seasonal temperature fluctuations. Its overall super-hydrophobic property keeps the volume water absorption rate below 8%, preventing wall dampness and mold growth, thus creating a dry and healthy living environment.
● Green Dimension: Low carbon and eco-friendly, aligned with health concepts.
The product is made from polylactic acid derived from natural minerals, industrial by-products such as desulfurization gypsum, and agricultural and forestry waste. The manufacturing process employs low-temperature calcination and ambient temperature molding, resulting in a lifecycle carbon emission level of approximately 30% that of traditional rock wool materials. The material itself is safe, non-toxic, and free of harmful volatile substances, aligning well with the concept of healthy housing construction.
Currently, the aerogel insulation board has established a comprehensive standard system, including CECS product standards, CSUS engineering and technical standards, national specialized drawing sets, and Anhui provincial local standard drawing sets. The technological achievements have passed authoritative scientific and technological evaluation, providing solid support for the standardized application in high-quality residential construction.
2. Empowering the Renovation and Upgrading of Existing Buildings to Unlock Long-Term Value
In response to the planning directive calling for "steady progress in renovating urban villages, dilapidated housing, and aging urban communities, while supporting residents' self-initiated upgrades," polylactic acid-aerogel insulation boards—thanks to their lightweight nature, ease of installation, and long service life—have emerged as an ideal solution for thermal insulation retrofitting of existing buildings.
China has a large stock of existing buildings, many of which suffer from inadequate thermal insulation, aging exterior finishes, and significant safety hazards. Traditional renovation methods often face challenges such as limited structural load capacity, long construction periods, and short service life. Polylactic acid-aerogel composite insulation boards effectively address these issues:
● Lightweight and low load-bearing, suitable for aging building structures. With a bulk density of only 80–100 kg/m³, the product's self-weight is significantly lower than that of traditional insulation materials, greatly reducing additional structural loads during exterior wall renovations. No extra structural reinforcement is required, making it ideal for upgrading various existing buildings such as dilapidated housing and old residential communities.
● Flexible construction process shortens renovation duration. Compatible with multiple construction methods including thin plastering, integrated insulation-decorative panels, and structural-insulation integration systems, the product simplifies procedures and reduces on-site labor, effectively shortening project timelines and minimizing disruption to residents' daily lives. Its excellent dimensional stability eliminates issues like wet expansion or dry shrinkage, ensuring smooth, durable walls after renovation with minimal cracking or peeling.
● One-time renovation delivers long-term benefits, reducing costs and improving efficiency. The inorganic mineral-based material provides exceptional weather resistance and durability, enabling stable thermal performance over the long term. This avoids the need for frequent replacements typical with conventional insulation materials, significantly enhancing the overall cost-effectiveness of renovations in aging neighborhoods.
Currently, Aerogel Crystal insulation boards have been successfully applied in numerous urban renewal projects across China, earning market recognition for their reliable performance.
III. Practicing the Circular Economy Concept for Low-Carbon Transformation in the Housing Sector
In addition to directly meeting the needs of housing construction and renovation, the polylactic acid-aerogel insulation board embodies a circular economy model that aligns closely with the long-term green and low-carbon development direction of the housing sector.
The main product component consists of naturally stable inorganic mineral crystals. At the end of its service life, these inorganic minerals can be crushed and ground, then recombined for reuse. The polylactic acid foam particles can be separated and composted to degrade, returning to the biological cycle. This enables comprehensive recycling and effectively reduces construction waste. Meanwhile, the production process can utilize industrial by-products and agricultural or forestry waste, supporting the green transformation of the building materials industry and giving "good houses" a deeper ecological meaning.
Housing is essential to people's livelihoods and a key driver of consumer upgrading. The implementation of the "15th Five-Year Plan for Expanding Consumption" has opened new opportunities for improving housing quality and advancing the green building materials industry. Anhui Beijia will continue to deepen its expertise in aerogel core technologies, continuously optimize its product systems and engineering solutions, and support the construction of "high-quality homes" with premium green building materials. The company will actively contribute to public welfare projects such as the renovation of aging residential communities and age-friendly upgrades, making ongoing efforts to promote high-quality development in housing consumption and build safe, comfortable, and sustainable living environments.
