New generation of Schöck Isokorb thermal bridge breakers in ITE/ITR

Its Isokorb range of thermal bridge breakers has just obtained a DTA (Technical Application Document) from the CSTB. This new certification notably makes Schöck the ONLY manufacturer of breakers to offer an ITE range for seismic zones as well as a range with an insulation thickness of 120 mm (Schöck Isokorb XT), in addition to the 80 mm range (Schöck Isokorb T).

From these two flagship references ensuring thermal insulation between the facade of a building and the projecting exterior concrete elements, Schöck deploys no less than 15 models depending on the fields of application. This exhaustive range of solutions, serving energy efficiency, thus offers absolute freedom of design that will appeal to all specifiers (architects, design offices, etc.). Indeed, this freedom is no longer restricted by the breaker which, thanks to Schöck, can treat thermal bridges on balconies, aligned balconies and even offset balconies (as well as loggias, canopies, acroteria, etc.), while ensuring their safety (structural, seismic, thermal and fire).

Finally, it should be noted that the implementation of Schöck Isokorb circuit breakers in the context of external walkways makes it possible to attenuate impact noise and therefore provides long-term acoustic insulation, without having to resort to dedicated floor coverings.

Among the new features

While all thermal breakers currently on the market have an insulation thickness of 80 mm (like Schöck Isokorb T), Schöck now offers a new reference, with a 120 mm insulation: Schöck Isokorb XT. This thickness is, for example, recommended for passive buildings, which allows Schöck to position itself as an exclusive player on PassivHaus projects and passive labels.

It should also be noted that Schöck Isokorb XT type K, designed for cantilevered elements, has the best thermal performance on the market with a psi value of 0,11 W/mK. This thermal performance is due to the fact that the fire-resistant plates in the lower and upper parts of the breaker, initially made of silico-calcareous material, were replaced by strips of rock wool protected by a PVC profile.

Another exclusive, the new Schöck Isokorb range is the only one under DTA of the CSTB for all seismic zones, all buildings, all heights. Indeed, it is enough to insert the Schöck Isokorb T type H module, between the breakers, to take up the seismic forces (point transmission of horizontal forces applied parallel and/or perpendicular to the isolation plane).

Finally, and this is a real step forward for construction professionals, Schöck has developed models that make it easy to handle offset balconies: Schöck Isokorb type KO (for floors with an upward height offset) and Schöck Isokorb type KU (for floors with a downward height offset). These two load-bearing thermal insulation elements transmit negative moments and positive shear forces.

Each configuration has its own Schöck Isokorb switch

• Types K, KO, KU, C and D: for cantilever elements
• Types Q: for elements on supports
• Type H: to withstand seismic forces
• Types A and F: for slab/acroterion connections
• Type O: for slab/facing support console connections
• Type B: for slit/beam connections
• Type W: for interior partition / exterior wall connections
• Types Z and ZS: insulation without through reinforcements

The advantages of thermal bridge breakers in ITE and Schöck support

The advantages of ITE are no longer in doubt: energy savings, reduction in heating bills, increase in household purchasing power, increased comfort for occupants and enhancement of real estate.

The benefits of using thermal breaks in ITE are just as obvious, knowing that they also help prevent condensation and mold responsible for many respiratory illnesses (bronchitis, rhinitis, asthma, allergies), thus contributing to better indoor air quality.

Simple, safe and quick to implement solutions, Schöck Isokorb circuit breakers display optimal operationality, thanks in particular to arrows indicating the direction of execution as well as QR Codes referring to the installation instructions… The entire range can be found on the CAD/BIM library, Schöck also offers layout plans, as well as the possibility of support, on request, on site or in the prefabrication plant. Finally, in order to always better support professionals, Schöck has just published a complete ITE installation guide.

The various breakers in the Isokorb T and XT range for concrete-concrete connections can be found on the Schöck website: Concrete-concrete bond – Schöck France SARL (schoeck.com)

It should be noted that the range of Schock circuit breakers dedicated to ITE is truly exhaustive because it also includes references for treating steel-steel, steel-concrete and wood-concrete connections.
