该地区窗膜需求的驱动因素
加州Title 24能源法规为新建筑设定了最低窗户性能标准。窗膜可以使旧房达到并超过这些标准，而无需更换窗户。
加州高太阳强度、晴朗天空和温和冬季的组合使住宅窗膜成为全年性能升级——而不仅仅是夏季解决方案。
低辐射改装窗膜 的工作原理
穿孔膜解决了私密性与采光的权衡问题。微孔图案在白天从内部保持向外的视野，同时阻挡从外部的视线。
混合膜将陶瓷颗粒与金属层结合，实现最大热量排斥。它们是极端太阳能暴露或拥有非常大朝西玻璃区域的家庭的正确选择。
为什么窗膜是您家的最佳选择
Housing Authority of the County of Alameda (HACA) in Hayward has a combination of high solar intensity, energy-efficient windows, and premium residential construction. 低辐射改装窗膜 is one of the most effective solutions for this climate profile.
