Far IR Transparency - steve hicks - 12-07-2012 02:46 PM

Hi All
I realize that this is not technically a question for this site but I really need some help.
I have a Far IR heating in my study. However the surface of the unit gets very hot and I am worried my toddler daughter will touch it and burn her hand. I need a material which behaves like germanium which will allow the IR through but not heat up itself. I need a fairly thick material, some kind of plastic so I can build a frame and have a small air gap between the emitter and the panel but will not be damaged by my daughter touching it. Obviously cost is a factor here or I'd just by a new heater. The IR heater is 600mm square.
Many thanks for your assistance.

I assume your heater is using a quartz tube element? I am sorry but I cannot think of a low cost material that would work (without seriously reducing the heat provided and pose a melting or fire hazard itself).

You might consider putting a cage in front of the heater. You could use an expanded metal mesh or screening or chicken wire. You might consider painting the hot side silver and the room side a flat matte color so that it does not get too hot.

Please don't consider this to be professional advice - I don't know enough about your heater to offer professional advice. In other words, take this with a grain of salt.
