Poroton FZ8 for a single-family house

I lack the knowledge here of when one speaks of object constructions.

"Object business" is said in the floor covering trade, furniture trade, etc., when someone orders a hectare of needle felt or container loads of stacking chairs – basically whenever an order volume approaches a whole day's production. For this sales channel, there are special, above-average durable qualities. Objects in the sense of your stone can be school centers, hospitals, residential complexes, or the like. Probably your stone crumbles less, absorbs the mortar better, or wears the saws less. For example, there are stones/wall elements that are 60 instead of 50 cm long because in object construction different grid dimensions are considered. Possibly your builder takes the same stones for the single-family houses from the central warehouse that he also uses to build high-rise buildings. "Nothing to be afraid of," the hero would say ;-)
