Schöck Isokorb system was chosen for a major redevelopment project in North London.

Kings Crescent Estate, in Stoke Newington, North London is undergoing an ambitious five-year redevelopment project as part of the London Borough of Hackney’s wider Estate Regeneration programme.

The plan is to recreate a neighbourhood of high quality housing and pleasant tree-lined streets that sits comfortably with the surrounding Victorian townscape of terraced and semi-detached housing close to Clissold Park. The residential element of the scheme will result in up to 765 new homes, intended to offer at least a one-for-one replacement for the present amount of housing on the site.

There are a significant number of balconies throughout the development and this means the risk of thermal bridging at the many cantilever balcony connections. There are two major consequences of this. One is local heat loss, resulting in more energy being required to maintain the internal temperature of the building. The other being condensation, which is more serious for the building occupants.

To counter any such risk, the design incorporates two types of structural break units from the extensive Schöck Isokorb range. First there is the Isokorb type KS, a concrete-to-steel connectivity module that sits between the outer and inner structural connection points and blocks the outflow of heat through the use of a high-quality polystyrene insulation core. Secondly there is the Isokorb type QS moduleIn principle the type QS has the same functionality as the KS, but it does not transfer bending moment.

The diverse range of Schöck Isokorb load-bearing thermal insulation solutions guarantees totally verifiable performance standards, meets full compliance with the relevant UK building regulations and offers BBA Certification and LABC Registration. In addition to providing highly effective connectivity solutions for concrete-to-steel thermal bridging situations, the Schöck Isokorb range also offers a modular product for concrete-to-concrete and steel-to-steel applications.

The range also complies with the Government Standard Assessment Procedure, SAP 2012, concerning CO2 emissions from buildings and respectively heat losses through non-repeating thermal bridges. The lambda values of the Isokorb enabling energy loss to be reduced by as much as 84% to 91% in various connective situations.
