Latest generation Schöck Isokorb® to PassivHaus standard

Latest generation Schöck Isokorb® to PassivHaus standard

For almost thirty years, the Schöck Isokorb® product range has led the market in providing exceptionally high performance thermal break solutions. Now, the latest generation for concrete-to-concrete applications, the type KXT, pushes the boundaries even further; offering architects and engineers a greater variety of design options.

There is the capability to construct stepped height balconies, for example, with increased fire protection also taken in account as the HTE module offers fire-resistance class F 120.

Even more significantly, the PassivHaus Institute in Darmstadt has awarded the new Schöck Isokorb® KXT with the "low thermal bridge construction" certificate and has therefore confirmed its suitability for PassivHaus construction.

A major reason for the superior performance of the new type KXT is the improved HTE module, which has been increased to 120mm in length and now contains ‘Kronolith’, a titanium ore aggregate from Kronos Titan. The new type KXT not only improves thermal insulation performance by up to 30%, it also improves impact sound insulation by around 50% as well.

A high quality stainless steel with improved tensile strength is an integral part of the unit and while the same load-bearing capacity is maintained, there is a smaller rod diameter and therefore a reduction in the thermally conducting cross-section, resulting in a further increase in the heat insulation performance.

The units are designed to help meet compliance with the UK building regulations. These state that the temperature factor used to indicate condensation risk (fRSI), as described in BRE IP1/06 (a document cited in Building Regulations Approved Documents Part L1 and L2 and Section 6 in Scotland) must be greater than, or equal, to 0.75 for dwellings. For commercial buildings it must be greater than, or equal to 0.5. Furthermore, it enables optimum compliance with the Building Regulations Approved Documents by using numerical modelling to calculate the building’s energy performance.

The KXT has already seen considerable success in Germany, not least for its sound insulation characteristics. For the first time in Germany there is now a stated minimum standard requirement for balconies. Previously this only applied to covered balconies, but the Schöck Isokorb® KXT has the advantage that it conforms to the minimum requirements for impact sound protection without any additional floating flooring on the balconies or covered balconies.
