Latest Schöck BBA Certification raises the bar

The latest BBA Certification awarded to the Schöck Isokorb is the culmination of an unprecedented standard of assessment by the BBA. It has resulted in a much more demanding new generation of Agrément Certificates for thermal break products and the emergence of a new ‘Leader Certificate’. This new ‘Leader Certificate’ incorporates significantly more detailed content on structural stability and performance of the balcony connector.

The rigorous assessment by the BBA involved tests for structural stability, fatigue stresses and fire. As a result, the enhanced Certificate includes a full description and specification of each component. Specification of threaded steel bars to connect the system to steel balcony; limitation for deflection of the concrete slab and steel; the requirement for fatigue stresses due to different temperatures and for natural frequency of the external concrete slab and steel balconies; thermal bridging at the junction between the balcony and the wall. In addition, it covers behaviour in relation to fire.

The BBA’s Project Manager, Seyed Tajallifar, emphasises that: “All future Agrément Certificates of this sort will follow this format. The items covered in the Schöck Certificate will be included in any other balcony connector Certificate when they are due for Reissue.”

Chris Willett, MD at Schöck comments: “We have always welcomed our collaboration with the BBA, which dates back over several years. This new generation BBA Agrément Certificate takes a huge step in providing the highest level of assurance to the construction industry and we are certain that it will lead to further specifications of our product in the future”.
