HOW TO DIFFRENTIATE BETWEEN CW SYSTEMS
The requirements posed on facade constructions have increased steadily over the past decades. After the oil crisis the first regulations concerning the energy consumption of buildings were drawn up. Furthermore, an increasing number of codes and directives were created that deal with environmental pollution, product and user safety.
The building industry was forced to set and enforce new standards, particularly in terms of building physical aspects. Certification reports had to prove that certain thermal insulation properties, air and water tightness of the curtain wall were maintained.
Weather-tightness of the building envelope is one of the major issues facing the construction industry. Too many new buildings are leaking due to inadequate design and construction.
The causes are simple, but reliable solutions are elusive. New materials often present unexpected integrations.
