Driven by the "Dual Carbon" goals and urban renewal initiatives, China's building materials industry is undergoing a profound green transformation. According to the Implementation Plan for Promoting Equipment Updates in the Industrial Sector released by seven departments, including the Ministry of Industry and Information Technology (MIIT) in 2024, the green retrofitting of the building materials industry has become a top priority.
Innovation in Warm Edge Technology: The Advantage of PP Warm Edge Spacers Among various warm edge solutions, the PP Warm Edge Spacer is standing out due to its superior sealing stability and thermal performance. Unlike traditional corner-key processes, the PP Warm Edge Spacer integrates multiple high-performance composite materials through a seamless co-extrusion process. This not only blocks heat loss at the edges but also significantly extends the service life of insulating glass.
With the continuous release of demand for industrial equipment updates and energy-saving renovations for existing buildings, the insulating glass industry has bid farewell to the era of "low-price competition." Embracing warm edge technology and deepening systemic energy efficiency will be the key for building material enterprises to lead the way on the green track.
2025建筑节能新风口：中空玻璃如何靠“暖边”赢得绿色未来？
在“双碳”目标与城市更新的双重驱动下，中国建筑建材行业正迎来一场深刻的绿色变革。根据工信部等七部门2024年发布的《推动工业领域设备更新实施方案》，建材行业的绿色化改造已成为重中之重。作为建筑外围护结构中能耗占比最大的部分，玻璃系统的节能技术升级，无疑是这场变革的“风向标”。
从“能用”到“节能”：行业标准重塑 进入2025年，中空玻璃行业不仅在产量上保持稳步增长，更在质量与性能上实现了跨越。随着超低能耗建筑（Passive House）标准的普及，传统的铝条中空玻璃由于铝材极高的导热系数，容易形成明显的“冷桥”效应，导致边缘结露、发霉甚至密封失效。最新的行业调研显示，新一代绿色建筑对玻璃系统的K值提出了近乎苛刻的要求。在这一背景下，“暖边技术”从幕后走向台前，成为高性能节能玻璃的标配。
暖边技术的革新：共挤工艺的优势 在众多暖边解决方案中，共挤暖边条（Co-extruded Warm Edge Spacer）正凭借其卓越的密封稳定性与热工性能脱颖而出。不同于传统插角工艺，共挤工艺通过高性能复合材料的无缝集成，不仅阻隔了热量在边缘的流失，更大幅提升了中空玻璃的使用寿命。
对于B2B端的玻璃加工商和建筑承包商而言，这不仅是材料的替换，更是供应链竞争力的升级。在2025年的市场竞争中，采用共挤暖边技术的中空玻璃，不仅能完美适配国家的绿色改造政策，更能为终端用户带来长效节能收益。
随着旧房节能改造需求的持续释放，中空玻璃行业已告别“低价竞争”时代。拥抱暖边技术、深耕系统节能，将是建材企业在绿色赛道上领跑的关键。
