2 ARCHITECTURAL TERRACOTTAWhile technology has continuously progressed, themanufacture of clay-based construction materials stillcentres on the three elements of fire, water and clay as it has done for millennia. Exploiting all the age-oldtraditions, skills and workmanship necessary for proces-sing the material clay, Niederrheinische Baukeramik(NBK) has developed the TERRART terracotta faade

system.TERRART is a ventilated curtain wall/rainscreensystem whose exposed components are made exclusi-vely from terracotta. This was the key requirementimposed on the NBK development team by RenzoPiano for the Potsdamer Platz scheme the startingpoint for the presentday TERRART-system.

The system components are manufactured so as tomaximize shape accuracy and guarantee best fit.State-of-the-art drying and firing techniques allow anearly tolerance-free production of units up 180 cm

long. The TERRART rainscreen system apatented developed within the TERRART productrange comprises a mere 15 individual componentsand ensures excellent integration of the system in anyclassical and contemporary wall construction.

With its Large, Mid and Shingle ranges, the versa-tile TERRART-system offers architects maximumscope for creativity. Purpose-made project-specificdevelopments provide designers with practicallyboundless options. The gobal success experienced bythe TERRART-system is documented in this book.Many of the buildings that feature a TERRART faadeare prime examples of forwardlooking architecture.

Enthusiastic architects draw inspiration from compo-nents whose shape, colour and finish may be suitablyorchestrated to produce striking faade designs.Satisfied clients can delight in buildings oftremendous aesthetic appeal, while reaping the benefitsof one of the most weather resistant constructionmaterials available.

TERRART has opened up a complete ly new dimensi-on in faade design and received worldwide acclaim.Every new building serves as an impetus for furtherprojects. What all schemes share is exceptional archi-tecture.

Today, the TERRART-system developed by Nieder-rheinische Baukeramik is used in all its variants acrossthe globe. The most distinguished of architects havecome to appreciate the tremendous creative possibili-ties offered by this terracotta faade system, whichcombines traditional craftsmanship with leading-edgemanufacturing technology. Its ability to accommodateeven the finest design details in terms of shape, colour,texture and glaze paves the way for unique, tailored

solutions.

COLORS AND TEXTURES 1

TERRART natural and honed finishes are beingincreasingly exploited as a design feature incomtemporary architecture.

NBKs expertise in complicated mixing techniquesand traditional firing methods, allows virtually anycolour and sorface texture specification to be met tothe letter. This allows our company, in consultationwith designers of exclusive product assortments, tomake unique buildings.

The colours shown represent only a few of ouroverall range. Any required shade can be providedupon request.

A multitude of profiles are available, the broaddesign spectrum ranges from the finest structure upto the strongly profiled plastic relief.

4 ENGOBESTERRART engobes are becoming more and morepopular.

Whenever theres a need for a colored surface on theone hand but to conserve the natural character of thematerial on the other hand engobes are that perfectalternative.

An engobe is a white or colored clay slip coatingapplied to a ceramic body to give it decorative coloror improved texture.

Engobes are manufactured in a single-fired processand do not have any coated edges.

TERRART engobes are also developed in ourlaboratories according to the architects demands,they are limited in their range of colours because oftheir specific mixture of raw materials but opening upa completely new dimension in facade designbecause of their unique and distinctive character.

TERRARTengobes create buildings of tremendousaesthetic appeal, while reaping the benefits of one ofthe most weather resistant construction materialsavailable.

GLAZES 1

TERRART glazes are being increasingly exploitedas a design feature in contemporary architecture.NBKs expertise in complex mixing techniques andtraditional firing methods allows practically any colorand surface texture specification to be met to theletter. This permits manufacture, in consultation withdesigners, of exclusive product assortments to makeunique buildings.

All of the glazed components from the TERRARTfaade systems are mostly twice-fired and provide

guaranteed weather and frost resistance. In principle,nearly any RAL color can be produced. Provision ofan original sample is essential when specifyingcolors.


16/24

Remarks:The tiles are ceramics made from natural materials, so small variations in color, size and consistency from the sample faade are unavoidable. All other formats, dimensions and speziasizes are available on inquiry basis.Subject change without notice.Glazed terra cotta faade tiles and elements could show hairline cracks called Craquel. This is a well know effect o

glazed terra cotta ceramics which could appear in a short or over a longer period of time. The Craquel will not affect any of the mechanical properties of the product.

TERRARTRAINSCREEN SYSTEM 1

The NBK TERRART ceramic clay tile faade system,which is based on the rainscreen principle, is customdesigned and engineered.

The vertical joints are backed by a support systemwhich drains rainwater away from the cavities behind.The gaskets, together with balanced air pressure,discourages water from entering the wall cavities.

The tile design allows for air to flow through openjoints, which helps to balance air pressure i n the

cavities behind the terracotta cladding elements withthat of outside air, hence, the term - pressureequalization.

Driven rainwater will not enter the cavities because ofthe overlapping joints (protected openings) and lackof pressure differential.

The back ventilation assists in maintaining a drycavity and negates the build up of hot air, an additionalbenefit to the TERRARTrainscreen system.
