ប្រព័ន្ធ Unitized

  The development of Unitised Curtain Walls (UCW) has increased greatly in recent years.  This is largely attributable to factors such as the increase in building height, the demand for recladding of old buildings, and increasing completion of construction schedule,  drive to reduce “on site” programmes.
UCW consists of manufactured and pre-glazed floor high units or panels normally constructed from aluminium profiles that are fully completed prior to going on site, including all fenestration choices from glass, stainless metal panels, insulated spandrels to stone cladding.
