I don't have a very complete answer, but I've been looking into this.
Some things that either absorb or reflect infra-red light:
-Plexiglass
-Water
-Some Mirrors
-The coatings of some cool-colored light-bulbs.
-Some Red Paints
-A cloth that gets especially hot in the sun. It's hard to tell with black cloth, because it absorbs so many other spectrums of light. If you find a light-colored cloth that for some reason gets hotter in the sun than other cloth, it probably absorbs infra-red.
-The effect of Aluminum foil may be useful in distributing heat and blocking.
-Some sunglass lenses
-Most Plants
There are some other substances and filters that are kinda hard to find or use, but apparently, some Japanese company is making underwear that blocks infra-red.

Apparently they're made of nylon and polyurethane.
Hope that helps!
What else can I help you with?
Show ftir block diagram?
A typical FTIR (Fourier Transform Infrared Spectroscopy) block diagram includes several key components: a broadband infrared light source, such as a Globar or laser, which emits infrared radiation; an interferometer that modulates the light; a sample holder where the sample interacts with the infrared light; and a detector, typically a photoconductive or pyroelectric detector, that measures the transmitted or reflected light. The output from the detector is then processed by a computer to perform Fourier transformation, converting the time-domain signal into a frequency-domain spectrum for analysis. The resulting spectrum provides information about the molecular composition and structure of the sample.
Why is gold used as the reflective surface of some solar panels?
A thin layer of gold that is transparent to visible light but reflective to infrared light is used to keep the temperature of the panels down. This is important in space where the atmosphere does not block solar infrared light, but not needed on the surface of earth.
Is infrared man made?
No. Infrared is light (that we can't see) and light is NOT man made.
Why was Infrared photography developed?
Infrared photography was developed to give the consumer more choices for the type of picture produced from one image. With infrared, a picture can be in color, in distorted colors, or even in black and white, all from the same image.
What is the IR Infrared blaster or IR Controller is used to?
An infrared blaster (or IR blaster) is a device that emulates an infrared remote control to autonomously control a device that is normally controlled only by remote control key presses.IR Blaster is used to change the channel .
Does aluminum block infrared cameras?
i think it does if not glass will...!
What blocks infrared cameras from detecting heat signatures?
Certain materials, like glass and certain plastics, can block infrared cameras from detecting heat signatures because they are transparent to infrared radiation.
What do infrared cameras look for in substations and on power lines?
What do truck-mounted infrared cameras look for in substations and on power lines
Where can one bulk purchase Infrared Security Cameras?
Infrared security cameras can help to keep families and properties safe. Infrared security cameras can be purchased at any retail store that sells home goods such as Home Depot.
Are there any websites that offer cheaper infrared cameras?
At Computergeeks.com I have found decently priced cameras for as low 23.00 each! They have a great assortment of infrared cameras, digital cameras, computers and SO much more!
Which companies sell good infra red cameras?
If you are looking for Infrared Cameras, Infrared Cameras Inc. is the place to shop. They offer the highest quality product, which they manufacture themselves, for the best price.
What do night vision cameras use?
infrared spectrum
How does the infrared cameras work?
Infrared is like light with a wavelength beyond the range of human eyes. It can however be picked up by infrared photographic film and digital sensors (digital cameras usually have a filter to block it out though). When taking infrared photos an infrared filter is needed in front of the lens to block out the visible light.
How do you block infrared detectors?
Glass is known to completely block infrared waves from a detector. Aluminium foil no answer.
Will Infrared illuminators work with any camera?
No. They only work with cameras that can focus via infrared light.
Are red light cameras use infrared or flash cameras?
Red light cameras are usually high speed video cameras that use ambient light.
How can I effectively block infrared radiation?
To effectively block infrared radiation, you can use materials that are opaque to infrared light, such as metal foils, certain types of glass, or specialized films designed to block infrared radiation. These materials can absorb or reflect the infrared radiation, preventing it from passing through.
