Riverwalk in Millbank, Westminster, is a prestigious, multi-million-pound development on the banks of the River Thames in London. Architects Stanton Williams wrapped balconies around the scheme, creating the need for high performance thermal breaks to limit heat loss from the junctions of balconies with the main building structure.

Schöck Isokorb type KXT was the specified structural thermal break, delivering 120mm of insulation and improving thermal insulation performance by up to 30% in comparison with a standard 80mm range and impact sound insulation by around 50%.

Importantly Isokorb type KXT has British Board of Agrement Certification, achieved following an unprecedented standard of assessment by the BBA. The new certificate incorporates significantly more detailed content on structural stability and performance of the balcony connector.

stability and performance of the balcony connector. The BBA worked closely with Schöck to develop the new level of testing, with certification experts visiting its manufacturing plant in Baden Baden, Germany, and liaising over a four-month period.

Chris Willett, Schöck Managing Director, said: “With the BBA we were able to work objectively towards a common goal, that of raising the standard to which structural thermal breaks should be tested and approved in the UK.”
