Schöck Isokorb® type K-corner

Schöck Isokorb® type K-corner: Thermal break element for balconies around outer corners

Schöck Isokorb® type K-corner is used to complement Schöck Isokorb® types K and KF when building cantilevered external corner balconies. It transfers negative moments and positive shear forces. Schöck Isokorb® type K-corner always consists of a 1st layer element and a 2nd layer element. Breaking it down into two parts like this enables its use to be tailored to structural and design requirements.
