NBK Terracotta Cladding

NBK Terracotta is a ventilated curtain wall/rain screen system with exposed components made exclusively from terracotta.

The system moves water away from building envelopes, using a ventilated and pressure-equalised system.  Natural chimney effects not only keep the building dry to reduce maintenance, but also help save energy.  The NBK Terracotta support system — a patented development within the NBK product range — comprises a few individual components using 6063-T5 alloy, ensures excellent integration of the system.

Qualified NBK engineers design the Support System on a project-by-project basis to accommodate site specific Design, Seismic and Wind-load requirements.

Key Features
  • Durability — lifespan of 50 years
  • Marine grade alloy rail system, rust and corrosion resistant — Perfect for NZ's harsh conditions
  • Low maintenance — annual washdown completes the maintenance program
  • Rainscreen system repels 95% of water ingress providing extra protection against the elements
  • The low percentage of water absorption ensures that dirt does not penetrate the tile and make it look dirty
  • Inert material colour that will not fade with time
  • Outstanding colour consistency
  • Uses no sealants and is graffiti resistant
