Sustainable construction is generally seen as the concept of the future in the industry, as issues relating to life cycle assessment, maintenance outlay and follow-on costs are now part of the fundamental considerations that must be addressed by every forward-thinking building owner and by every prudent architect at the start of a construction project.
As a natural, environmentally friendly and particularly robust material, terracotta plays an increasingly important role in such considerations. Its excellent resistance to extreme temperatures, weathering effects and corrosion mean that this material maintains an unchanged high-value appearance even after many decades, making it an ideal façade material. Modern manufacturing and fi nishing techniques not only add infi nite variety in terms of design choices, but also ensure that the material is easy to care for, maintenance-free and virtually indestructible.
However, customers’ demands have long since moved on and now extend to more stringent requirements to ensure that the materials are emission-free and non-hazardous. The company NBK has reacted to this trend and now offers lead-free glazing. The NBK TERRART® ceramic façade has been officially certified by the German Institute for Construction and the Environment in terms of sustainability in accordance with ISO 14025. The validated declaration discloses all of the relevant environmental data – ranging from information about basic materials and material origins, to the entire product manufacture and processing procedure, through to disposal – and contains a description and definition of the ecological efficiency of the material, making it easy for the customer to understand and correlate all of the criteria without any gaps.
