Kolbe makes radius windows in stand-alone full circles, half-circles, quarter-circles, elliptical, ovals and custom shapes.
Half-circle or elliptical windows can be stacked over other Kolbe windows and doors to create larger window walls. We
build our radius windows to order so that their profiles match those of the windows they complement.
