Schöck Isokorb type KXT provided the ideal solution against thermal bridging for a high specification development in London.

Riverwalk is a striking new development at Millbank, on the north bank of the Thames. It features two organically shaped buildings connected by a central podium with 116 high specification apartments, plus penthouses.

The buildings are enhanced by horizontal bands of limestone on the curving fa-cades, with stonework wrapping around the lower parts of the balconies, creat-ing a continuous organic shape.

With such a high specification development, early consideration was given to the avoidance of the thermal bridging at the critical balcony connections and the Schöck Isokorb type KXT provided the ideal solution.

It offers such a high level of insulation, that in Germany the Passivhaus Institute in Darmstadt has awarded the product with the low ‘thermal bridge construction‘ certificate and confirmed its suitability even for Passivhaus construction. In the UK, the latest BBA Certification awarded to the Schöck Isokorb is the culmina-tion of an unprecedented standard of assessment by the BBA. Resulting in a much more demanding new generation of Agrément Certificates for thermal break products.

There are more than 12,000 standard types and solutions in the Isokorb range, allowing connections to be made between concrete-to-concrete, concrete-to-steel and steel-to-steel. All units meet full compliance with the relevant UK build-ing regulations, which require that the temperature factor used to indicate condensation risk (fRSI) must be greater than or equal to, 0.75 for residential buildings.

This is easily met by incorporating the Isokorb and in addition to the BBA Certifi-cation, the range also provides Local Authority Building Control Registration. There is compliance too with the UK government Standard Assessment Proce-dure (SAP 2012) concerning CO2 emissions from buildings and respectively heat losses through non-repeating thermal bridges. Here, the lambda values of the Schöck Isokorb enable energy loss in various connective situations to be reduced by as much as 84% to 91%.
