该地区窗膜需求的驱动因素
6月至9月间南加州下午的太阳角度足够低，可以将直射太阳辐射深入朝西的房间。标准窗帘遮挡视野；膜阻挡热量。
加州气候——大多数地区每年260多个晴天——意味着太阳热量增益是一个持续的挑战。窗膜在源头解决这个问题，而不会遮挡您的视野。
太阳能控制窗膜 的工作原理
住宅窗膜是解决太阳热量增益最有针对性的方案：它在源头——玻璃——解决问题，而不是通过更多制冷来补偿。
低辐射改装膜专为旧式单层玻璃窗设计。它增加了一层低辐射率，显著提高隔热性能——是1980年前加州住宅最具成本效益的升级。
为什么窗膜是您家的最佳选择
Sunnyvale Elementary School District in Sunnyvale has a local mix of solar exposure, window construction, and residential cooling needs. 太阳能控制窗膜 is one of the available solutions for this climate profile.
Effective against Sunnyvale's high solar irradiance
Compatible with double-pane low-e glass
Professional installers available in your area
10–15 year manufacturer warranty
安装与费用
安排安装的最佳时间是早上，在玻璃加热之前。热玻璃会导致滑动溶液蒸发过快，使膜难以正确定位。

Cure time
30 days full cure
窗膜类型对比
Burn pattern appears in a defined stripe or patch near a window
Damage is worst between 1pm and 5pm on sunny afternoons
The affected window is double-pane or energy-efficient
The burn pattern has shifted slightly over the past year
Turf replacement hasn't solved the problem — it keeps coming back
