Concrete light shafts
ACO concrete lightshaft- the robust all-rounder
ACO concrete light shafts (with and without base) made of reinforced exposed concrete provide sufficient light in the cellar, even under difficult conditions where conventional plastic light shafts are not sufficient for the task involved. The installation time is short as concrete work is not required on site. Numerous standard sizes ensure flexibility under a wide variety of conditions.
The concrete light shaft is suitable for all ACO Therm® reveal cellar windows and a large number of additional windows. A pressurised watertight installation can be implemented directly on water impermeable concrete walls or on insulated walls. ACO concrete top sections and attachments enable optimum adaptation to the desired light shaft height. The extensive range of accessories (backfill panels, light shaft covers and many others) leaves nothing to be desired.
