Hiding from Thermal Imaging Devices

As the U.S. military has found over the past couple of decades, night-vision equipment is a real game changer. The use of light intensification scopes and goggles have given our infantry and Marines a decisive edge; thermal imaging has played a similar role for military aircraft hunting insurgents. However, as the prices of thermal imaging equipment continues to fall, it raises the corresponding conundrum, as preppers, of protecting against thermal imaging equipment that raiders or looters might have.

I have theorized in the past that mylar space blankets might provide some concealment against thermal imaging, but had found nothing concrete on the topic and haven't had the money to buy and test equipment myself. However, I ran across this in a post to the Survivalist Blog reviewing the FLIR Scout PS24 thermal imager:

You can hide from thermal imaging. I found that glass acts as a mirror; a white-hot candelabra bulb is not visible through a double pane window standing only 2 feet away - all you see is your reflection in the window. Thermal images reflect off still water as well. I’d expect a space blanket “hide” to shield a thermal signature about the same.

It provides some food for thought.
