KOROK® External

We now have five external systems for you to choose from - two ColorSteel and two using our galv panel with over-cladding.

The KOROK® External Wall Systems are all-in-one wall solutions for fire, acoustic and weather protection in external applications.

KOROK® is lightweight and economical when used for fire-rated boundary walls in commercial constructions. Installation can generally be managed by a small installation crew and no cranes are required on site. Due to KOROK®’s lightweight composition, no specially engineered slab is required, leading to significant cost savings and programme advantages.

KOROK® External Wall Systems provide cost-effective weather-tight systems that offer an all-in-one solution covering pre-finished exteriors, superior fire and acoustic ratings and fast, easy construction, generally without the need for heavy lifting equipment.

Developed specifically for New Zealand conditions, KOROK® External Wall Systems can be used in most exterior situations including very high wind zones without the need for additional cladding.

KOROK® External Wall Systems offer solutions that enhance the fire and acoustic ratings without the need for extra internal framing.
