A schöck isokorb structural thermal break is a fabricated assembly that is cast into the concrete floor slab at the location of the building insulation layer.
Thermal break for concrete floors.
The thermal break insulates the interior floor slab from the exterior exposed slab edge while transferring the loads imposed on the exposed slab edge back to the interior floor slab.
Concrete placement shows concrete being placed on the top of the sheet polyethylene and a layer of xps insulation.
Remember that the thermal envelope is the boundary between the inside conditioned space and the outside.
Stones gravel keep the plastic from blowing away.
Photograph 4 is a thing of beauty.
A thermal break worthy of great artisans.
Rigid foam is a nice option because it provides an excellent thermal break between concrete and flooring.
The bars tie into the rebar.
The thermal breaks consist of a graphite enhanced expanded polystyrene module with stainless steel rebar running through the insulation for tension and shear resistance.
A thermal break to the perimeter of the floor slab between the slab edge and the foundation greatly increases r value.
Any gab in this thermal envelope is an avenue for heat loss known as a thermal bridge.
