This is a two or four-sided structural glazed, fully panelised system for low to medium rise applications. Glass is adhered on the outer edge of the extrusions, reducing the visual effect of aluminium as viewed from the outside. Either the horizontal transom line or the vertical mullion line can be highlighted through the application of glazing beads. Sun control fins can also be applied to the outside of the transoms to accentuate the horizontal line. Opening sashes can be incorporated in the façade without interrupting the ‘glass look.’
