Infrared radiation does not even pass through a sheet. However, anything that is in contact with a heat source will absorb some of the heat via conduction, and the absorbed heat may eventually be visible through an infrared viewer.
Only by radiation. Infrared waves waves don't require a material medium to pass through. Heat energy is transmitted even through vacuum in the form of infrared waves. We get heat energy from sun in this way.

That depends, short wave infrared radiation can travel through glass (hence the laser pointers and your TV remotes), but longer infrared waves get reflected. This is due to the design of glass so that we can see through it but the infrared heat radiation does not leave, thus improving efficiency.

The earth's atmosphere/plasma acts as a reflector for long wave infrared radiation.

Infrared penetrates through dust, smoke and plastic.
Radio waves are longer on the electromagnetic spectrum and can penetrate objects because they are less dense. Visible light and infrared light are shorter and therefore too dense to pass through objects.
In short, your initial assumptions are flawed. Every different chemical compound will allow light of some wavelengths to pass through, and will absorb some other wavelengths. In the case of glass and many acrylic polymers, they both appear to be clear because most of the light in the visible spectrum passes through. It is not generally true that glass allows infrared light to pass through, nor is it generally true that acrylic polymers will allow ultraviolet light to pass through. The infrared light absorbed by both acrylic and glass heats up the material by causing bending, stretching, and twisting of mmolecular bonds. The ultraviolet light absorbed by these materials generally causes ionization.

Some forms of electromagnetic radiation that can pass through glass are x-rays,gamma rays,ordinary light,microwaves,infrared and radio waves.
