According to a company selling the solution, traditional window film doesn’t just block visible and UV rays from the sun, but also catches the 2.4GHz radio waves that carry data in Wi-Fi and Bluetooth. Solar Gard, a new window film from Bekaert, forgoes the typical metalized particles for a—ahem—”nanotech” formula that provides up to SPF 285 protection from the nasty spectrums, but lets your data pass through unmolested.
If you’re interested (and want to get some real-world pricing), you can find an installer who uses Solar Gard at the product website.
