A glazing system is provided having two or are generally parallel panes or panels (13, 40) housed within a vented framework (11, 12, 19 - 22) to provide at least one vented air-space (15) therebetween. At least one of the panes or panels (40) is adapted to absorb solar energy and thereby 'heat' the air contained within the air-space (15) to cause convection currents therein. Inlet vents (20, 22) and outlet vents (19, 21) are respectively disposed above and below each of the panes or panels (13, 40) and by appropriate control of these it is possible to use the convection currents within the air-space (15) to vent air into or out of the building interior or to vent the air-space (15) externally of the building to cool the said at least one pane or panel (40). Preferably the invention provides for the coating or doping of glazing panels or a fluid filled solar panel (40) the combined optical transmission qualities of the constituent parts of which peat transmission of light highly visible to the human eye, but which provide absorption of solar energy outside that spectrum. <IMAGE> |
