QT tiles have been specially designed to be positioned in quarterturn or checkerboard format. They should be placed in the direction indicated by the arrow on the reverse, turning 90° alternately.
The ST tiles are designed mainly for monolithic installation, without the seams showing,thus achieving the unbroken look of a rolled carpet. But ST tiles can also be installed in the traditional checkerboard format.
