Larger units are installed more quickly, and have fewer mortar joints, than smaller brick. While larger units can create a distinctive language of their own (and provide a more unique scale to the wall elevation), Emperors, Super Emperors and Atlas units can also be slotted to duplicate the look or pattern of smaller brick. Schedules can be reduc ed, labor is saved, and moisture resistance is increased due to fewer mortar joints. Experience for yourself the creative possibilities of Interstate Brick. Masonry Designer.
