cool beans! got pics?? wrapped inside or outside? hubby's got a pole barn... needs to be insulated.. wonder if that stuff would make it too darn hot in the summer

One article seems to think that the reason this is just a "hoodie" and not a full garment is because a full garment would be against International Traffic in Arms Regulations.
If you want to make one yourself, this looks like a good place to start:

The Matrix is a system, Neo. That system is our enemy. But when you're inside, you look around, what do you see? Businessmen, teachers, lawyers, carpenters. The very minds of the people we are trying to save. But until we do, these people are still a part of that system and that makes them our enemy. You have to understand, most of these people are not ready to be unplugged. And many of them are so inured, so hopelessly dependent on the system, that they will fight to protect it.
Well, depends on the IR you are trying to defeat, and what you mean by defeated. An expensive but just about certain way to defeat FLIR is with an ambient-temperature pane of glass held 8" in front of your heat source blocking the camera. Even as complicated as that is, that still may not be the type of IR defeat you are going for. perfect IR invisibility is difficult, but possible, but the closer you are to IR invisibility, the more difficult it will be to hide your visible light profile.Originally Posted by ClydeCoulter
If I'm honest, I tend to think the best way may be to go about the inside and outside and get the same color of thermal insulating and not thermal insulating paint, and just draw camouflage patters in thermal paint outside to match the landscape, inside to break up any shapes, and then cover in one-color so no-ones the wiser. if you have a heat source inside over a few watts, the barn will (eventually) glow no matter what. insulation and ventilation will decide how long that takes at what kind of power source. disrupt any 'glow' that forms into at best something natural looking.
How much heat it radiates depends on its emissivity. This is why two objects can be at the same actual temperature but have very different brightnesses on a thermal image.
I don't have the emissivity of mylar handy. But maybe there are other materials involved here, perhaps in multiple layers?
No offense intended, but flying around looking at objects through NVG and FLIR does not equate to an understanding of the technology. Were you testing various materials for stealth purposes? If so, that's another matter, and I hope you'll share some ideas with everyone.With close to a thousand flight hours using NVGs and FLIR I have a pretty good understanding of it.

I'm sure that at least one spot that glows like a neon sign, that's the woodstove in the winter on the northwest corner. But I like the thermal paint idea.
It looks like these thermal clothing items are already available for purchase:

The downside is that they're pretty damned expensive. They're probably not worth it if a way can be discovered to improvise these things. Perhaps Mr. Harvey will be willing to share his methods.
There are also a number of patents for "thermal camouflage" that can be read and downloaded from Google Patents. See for example US Patent #7,832,018.

It was wrapped during construction over the purlins and trusses, just prior to putting on the metal roof and siding.
It helps keep it warmer in the winter, and cooler in the summer. I also insulated with 1.5" foam sheets in the walls and R19 fiberglass in the ceiling. It's 1792 sq ft with 9' ceilings and a 5/12 pitch roof, and I am able to keep it 65 degrees F in the winter when it is in the teens outside using only a woodstove.

Anyone good with a needle and thread? Any DIY sewing machine pros out there?
You can buy a 45"X10 yard bolt of "Insul-Fleece" for about seventy bucks. It's Mylar-lined fleece.
Hmm. I could wrap my entire house for how much??
If anyone is truly going to line their house with mylar, be sure to read up on the proper placement of vapor and air barriers within walls for your climate type. Placed improperly, a vapor barrier could lead to condensation within walls and mold problems.Anyone good with a needle and thread? Any DIY sewing machine pros out there?
