FAQ Schöck Isokorb®

What is Schöck Isokorb®?

Schöck Isokorb® is a load-bearing thermal insulation element. It minimizes thermal bridges in the building envelope between the interior and exterior structures. At the same time, it transfers loads from the exterior structures to the interior structurs.

Which types of buildings is Schöck Isokorb® used in?

Schöck Isokorb® can generally be used in all heated buildings with structures projecting from the building envelope. The common building types are made of steel or reinforced concrete. The typical buildings are high-rise residentials as well as institutional buildings such as schools, dormitories, museums, gymnasiums, etc.

Which connections can be achieved with Schöck Isokorb®?

The standard products can be used to connect the typical projecting components, such as cantilevered balconies, supported balconies, loggias, slab edges, and canopies. In addition, they can be used for customized solutions for nearly all applications and load situations in high-rise construction (e.g. foundations, attics, and more). Our Schöck specialists would be happy to assist you.

Can Schöck Isokorb® transfer earthquake loads?

The standard product range includes special modules for the absorption of earthquake loads. It is used in addition to linear connection (e.g. Type CM, type CV, type CMD) and can easily be incorporated into planning and standard designs.

Can Schöck Isokorb® be used if compliance with fire safety regulations is required?

If compliance with special fire safety regulations is required, Schöck Isokorb® can be supplied with fire resistance up to 120 minutes.

Which free cantilever lengths can be achieved with Schöck Isokorb®?

It generally depends on the load resulting from the structure to be connected. Balconies with live loads can be connected with a free cantilever length of up to 3m with the standard products. Secondary components, such as canopies, can also be connected with significantly higher cantilever lengths. Our Schöck specialists would be happy to assist you.

Which documents do the Schöck experts need to develop a technical solution?

  • Dimensioned floor plans and cross-sections of the component to be thermally separated
  • For reinforced concrete components: concrete quality, concrete cover, load assumptions
  • For steel structures: design loads at the connection (ULS factored)

On which basis are resistance and loads of Schöck Isokorb® established?

The load capacties of the Schöck Isokorb® have been determined in accordance with CSA A23.3-04 and CSA 16-09. The basis for assessment was verified by Halsall Associates Limited, Toronto, ("Evaluation of Isokorb® type K"*, December 15th 2010) for the concrete products and by Fast+Epp, Vancouver, for the steel products.

* Isokorb® type K corresponds to Isokorb® type CM. For further information please contact "Technical support".

Do the welding seams of the tension rods between the stainless steel and the reinforcement steel have a permanent load-bearing capacity?

Due to thermal insulation and corrosion protection requirements, stainless steel is used around the gap. In order to be able to manufacture the product more cost-effectively, the stainless steel bar is extended by welding reinforced steel at both sides until the required length is achieved.

This design is approved by several material test establishments and has been tried and tested for over 25 years. The flash butt welding method is used for the welded connection between stainless steel and reinforcement steel. The requirements for quality assurance of this black-and-white connection are very high and are met by internal quality control as well as third-party inspections.

How is Schöck Isokorb® shipped and packaged?

The Schöck Isokorb® products are delivered to the construction site as ready-to-install products. They are shipped on wooden pallets. The products are held together by wrapping foil and protected by means of special packaging material.

Which methods and tools can be applied to divide the Schöck Isokorb® products at the construction site?

Schöck Isokorb® is designed and shipped to the construction site in a standard length of 1 metre. In order to achieve connection lengths outside of the 1 metre raster, the product can be divided in the middle. A simple hand saw can be used to accomplish this. Please see the installation manuals for detailed illustrations.
