The Color-Line has been develop with a glazed rounding on front. The rounding runs throughout the Color-Line window sill and the broad water channel structurally prevents the underlying brickwork from being stained. Also, the space between the cath and the ridge stone is covered by a raised adge, wich prevents water getting into the cavity. The combination of the attractively coloured Color-Line bricks with the windowsills, which are available in virtually all RAL colours, presents a colourful and clear facade image.

The colourful windowsill series is also available as a ready-for-use component.
