Newly Declassified Window Film Keeps Out Snoops

Posted by kdawson on from the pricey-tinfoil-hat-for-your-house dept.

An anonymous reader writes to describe a newly declassified window film from CPFilms Inc. that could give war drivers fits. Scientific American has the story, which includes a rather dismissive comment by Bruce Schneier. "Once manufactured under an exclusive contract with the US government, this recently declassified window film is now available to the public. But don't expect to see it on store shelves anytime soon. Currently, it's only available directly from the manufacturer, and at prices that will likely make it prohibitive for all but the wealthiest home owners. The two-millimeter-thick coating can block Wi-Fi signals, cell phone transmissions, even the near-infrared, yet is almost transparent... It can keep signals in (preventing attempts to spy on electronic communications) or out, minimizing radio interference and even the fabled electronics-destroying electromagnetic pulse generated by a nuclear blast."

    have you ever heard a picture window? or say any window which doesn't open? Actually have you ever seen a house to be honest? I don't think I've ever seen one which has 100% screened windows.

    Yes, I own a house. Guess what? 100% of my windows have screens (except for my bedroom which has a window AC unit in the window during the summer, but otherwise has a screen). So sorry to blow your well-thought out theory, but my house, and all of my friends' houses all have screens on every one of their windows. You see, I like to open my windows to cool my house off sometimes, yet I don't like thousands of bugs in my house. That's where the screens come in. I know, it's crazy, but it's true...

    Where do you live that houses don't have screens? Bosnia? Maybe you need to move to a less impoverished area...

    I suggest you take a look outside your house. Maybe visit some show homes, maybe a homedepot, maybe go for a drive around town. Its quite common for homes to have windows which do not open. If the window doesn't open, who puts a screen on it? Why would you need a screen?
    Try not to let your head explode with the absurdity of the fact that some people have fixed windows in their house.
