The insulation of the whole shell begins with the foundation.
Using XPS-boards the integration of a floor heating is easy to install.
Pouring concreteXPS-boards do have a good insulation value. This way you ensure a well insulated foundation for your complete shell made from Styrostones/PIF/ICF.
If the floor heating pipes are clipped to the XPS-boards, concrete reinforced by steelfiber can be poured, saving you the installation of a mesh.
A flat and even surfaceis a precondition to continue with the settings of the Styrostones/PIF/ICF in a quickly manner.
The more uneven the ground, the more you have to balance out the base of the shuttering with wedges.
A laser alignment device will help a lot to make sure for a complete horizontal and flat foundation.
