Terracotta

 

 While technology has continuously progressed, the manufacture of clay-based construction materials still centres on the three elements of fire, water and clay - as it hasdone for millennia. Exploiting all the age-old traditions, skills and workmanship necessary for processing the material clay, Niederrheinische Baukeramik (NBK) has developed the NBK facade system.

NBK is a ventilated curtain wall/rainscreen system whose exposed components are made exclusively from terracotta. This was the key requirement imposed on the NBK development team by Renzo Piano for the Potsdamer Platz scheme - the starting point for the presentday NBK system.

The sustem components are manufactured so as to maximize shape accuracy and guarantee best fit. State-of-the-art drying and firing techniques allow a largely tolerance-free production of units up 190cm long. The NBK-Flex support system - a patented developed within the NBK product range - comprises a mere 15 individual components and ensures excellent integration of the system in any classical and comtemporary wall construction.

With its "Large", "Mid", and "Shingle" ranges, the versa-tile NBK-system offers architects maximum scope for creativity. Purpose-made project-specific developments provide designers with practically boundless options. The gobal success experienced by the NBK-system feature a NBK facade are prime examples fo forwardlooking arhictecture.

Enthusiastic architects draw inspiration from components whose shape, color and finish may be suitably orchesreated to produce striking facade designs. Satisfied clients can delight in building of tremendous aesthetic appeal, while reaping the benefits of one of the most weather resistant construction materials available.

NBK has opened up a completely new dimension in facade design and received worldwide acclaim. Every new building serves as an impetus for further projects. What all schemes share is exceptional architecture.

Today, the NBK-system is used in all its variants across the globe. The most distinguished of architects have come to appreciate the tremendous creative possibilities offered by this terracotta facade system, which combines traditional craftsmanship with leading-edge manufacturing technology. Its ability to accommodate even the finest design details in terms of shape, color, texture and glaze paves the way for unique, tailored solutions.

    • Rainscreen System
    • Baguette System

    NBK clay tile facade system, which is based on the rainscreen principle, is custom designed and engineered.


    NBK Flex Rainscreen System


    The NBK clay tile façade system, which is based on the rainscreen principle, is custom designed and engineered.
    The tile design allows for air to flow through “open joints”, which helps to balance air pressure in the cavities behind the terracotta cladding elements with that of outside air, hence, the term – pressure equalization.
    Driven rainwater will not enter the cavities because of the overlapping joints (protected openings) and lack of pressure differential.
    The “back ventilation” assists in maintaining a dry cavity and negates the build up of hot air, an additional benefit to the NBK rainscreen system.
