Thermal Break For Concrete Floors

Stones gravel keep the plastic from blowing away.
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. Notice that there is no welded wire mesh. Any gab in this thermal envelope is an avenue for heat loss known as a thermal bridge. The bars tie into the rebar.
A thermal break to the perimeter of the floor slab between the slab edge and the foundation greatly increases r value. Photograph 4 is a thing of beauty. Rigid foam is a nice option because it provides an excellent thermal break between concrete and flooring. The sides of the concrete slab also referred to as the perimeter wall is often forgotten or not considered at all with respect to the thermal envelope.
Concrete placement shows concrete being placed on the top of the sheet polyethylene and a layer of xps insulation. 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 worthy of great artisans.
