The greater the conductivity, the greater the blocking. Aluminum foil will kill all IR, both high range and low. Most plastics allow IR to pass through. Glass will bock low frequency IR (red hot), but allow the passage of high frequency (white hot) IR.<br/><br/>Lead is a poor conductor real world, so it will poorly block IR. I mean, it'll block it better than nothing, but you could in theory sandwich a sheet of aluminum foil between two pieces of lead lining and it'd be perfect.
