什麼是Y-Tong block?

Y-Tong block is a brand name of drywall. It is a kind of factory made wall panel. It replaces the traditional brick and block dividing wall in buildings. It involves less labour and skill requirement, and provides a shorter construction time, better product quality and higher flexibility for future layout changes. Full height panels are assembled and conduits can be easily installed through its preformed tubular spaces with minimal cutting, jointing and patching up. Its lightweight characteristic, at about half the weight of solid concrete block reduces the dead load imposed on the building structure. The surface of the wall panel can be easily finished with a thin coat of skim plaster in lieu of the thick cement sand plaster in traditional block wall. Much less wet trade work is involved in the assembly process and less construction waste is generated at the end.
