Abstract:
1. Process for making a brick, comprising the steps of: a) prearranging at least one pair of half-shells, each half-shell having an interior wall; b) fixing said half-shells to each other to define a main body of said brick with a cavity therein; and c) introducing a preset quantity of argon into said cavity; d) prearranging at least one reflecting sheet and locating said at least one reflecting sheet between said half-shells, wherein said at least one reflecting sheet reflects a portion of incident infrared radiation, the step of prearranging least one reflecting sheet comprises fixing said reflecting sheet to one of said half-shells and fixing said other half-shell to said reflecting sheet thereby forming said brick; and e) prior to fixing said half-shells to form said brick, prearranging at least one additional reflecting sheet inside each half-shell spaced from said interior wall to provide said brick with a plurality of spaced reflecting sheets in said cavity thereby increasing the thermal insulation while maintaining structural rigidity.
