Is there an easy to obtain material thats transparent to infrared? It doesnt matter wheter or not its transparent to visible and uv

Depends on what you mean by "infrared," as well as what you mean be transparent." There's near-IR (NIR), which goes from about 800nm to 2500nm. Medium wavelength IR (MWIR), going from 3000 to 5000 nm, and Long wavelength IR (LWIR) going from 8000 to 14000 nm.
If by transparent, you mean transmissive, then fine, otherwise you'll need to clarify.
NIR is transmitted by almost all silica-based glasses as well as a vvariety of plastics and polycarbonates. In fact, typical PCs used in sunglasses are actually more transmissive in NIR than the visible.
MWIR can be transmitted by sapphire, diamond, silicon, germanium, zinc selenide, zinc sulfide, magnesium fluoride, and some others I can't remember
LWIR can be transmitted by germanium, silicon, zinc selenide and some plastics.

This company claims to have that type of material, http://www.eplastics.com/Plexiglass_Acrylic_Sheet_Infrared_Transmitting. Probably cheaper than glass product if it suits your need.
As others stated Schott is good if you have a specific application in mind. They have a website you can search for infrared transparent materials and applications
You can also get an infrared camera filter from a photo shop or online.

Schott makes a variety of infrared transmitting glasses that are black in the visible. Look for RG series filter glass. They have numbers like RG830, where 830 is the cutoff wavelength. But if you don't care about visible light, most common glasses have fair transmission well into the infrared.

You can buy cold mirrors which are specifically desgned to transmit infrared and reflect visible light. Most ordinary glass transmits near infrared (~ 1um) very well. If you are talking about far infrared (>10um) it will require special materials. In the far IR germanium is sometimes used.

You will find that rigid vinyl, polycarbonate and acrylic are all transparent to near infrared.

energy can be absorbed through molecular vibration in addition to electron excitation, and that is pretty well what we consider heating, increasing the kinetic energy of the particles (I am suggesting that the energy in the IR is absorbed by the atoms as kinetic energy rather than the electrons as ionizing energy). I suspect that reflection versus transmission should also come into consideration but that depends on the nature of the air-solid interface. A microwave oven heats by exciting the bonds and not the electrons, and microwave has even longer wavelengths than IR. Not an ionizing energy.

Some 4 x 5" film plastic holders may or may not be transparent to IR. Check and see.
