Sarana Tile lists ADSR as an 11" x 11.4" glass mosaic. On the residential side that covers kitchens, entry foyers and open-plan living areas. The nominal size is 11" x 11.4", listed metrically as 28.89x27.94cm. Each sheet covers roughly 0.87 sq ft. It appears in the Sarana Volume 8 catalogue at page 6. It arrives mesh-mounted, so the spacing holds while the sheet is set and it trims down to meet a corner or a niche. Sarana prices it by the sheet.
