该地区窗膜需求的驱动因素
低辐射玻璃是窗户效率的重大进步。但它有局限性。低辐射改装膜进一步延伸了这种性能，增加了现有玻璃所缺乏的第二层辐射率。
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，费用仅为更换窗户的一小部分。
防反射窗膜 的工作原理
大多数住宅窗膜安装可在一天内完成。膜在30天内完全固化，之后性能达到额定规格。
穿孔膜解决了朝街房间的私密性与采光权衡问题。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。
为什么窗膜是您家的最佳选择
Crawfords in Los Angeles has the typical Southern California combination of high solar intensity, energy-efficient windows, and premium residential construction. 防反射窗膜 is one of the most effective solutions for this climate profile.
