该地区窗膜需求的驱动因素
穿孔膜通过一个简单的光学原理实现单向私密性：白天室内比室外暗，因此图案从外面可见，但从里面是透明的。
南加州的圣安娜风条件创造了异常清晰、干燥的空气期，放大了太阳强度。在这些事件期间，未贴膜的窗户可以使室内温度比设定温度高8-10°C。
太阳能控制窗膜 的工作原理
太阳能控制膜是住宅窗膜的主力产品。它在保持清晰视野和自然采光的同时，阻挡40-70%的太阳热量增益。
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
San Francisco County Transportation Authority in San Francisco has the typical Southern California combination of high solar intensity, energy-efficient windows, and premium residential construction. 太阳能控制窗膜 is one of the most effective solutions for this climate profile.
