A construction unit used in the construction of walls, buildings and other structures and is particularly applicable to a construction unit in the form of a brick. The construction unit comprises a metal shell in the form of an open-topped waste steel can 3 having a glass core 5. The glass core 5 is a solid glass core provided by a quantity of waste glass cullet which has been heated in the can to fuse the cullet, before being allowed to cool. The construction unit 1 may have a plurality of linking members in the form of metal wires 7 extending from one end to the other through the entire length of the glass core and projecting from its ends 4, 8. The wires may facilitate joining of the construction unit to other construction units in use. Later embodiments relate to a method of producing said construction unit; a construction unit comprising a glass insert and a non-glass outer shell; and a construction unit comprising a metal outer shell (32 figure 5), a metal inner insert (34 figure 5) and a glass sleeve insert (36 figure 5) located in a cavity defined between the metal shell and the metal inner insert. |
