One of the best ways to save money on rigid foam insulation installed under concrete slabs is to ensure the material is not over engineered.
Knauf climafoam xps board delivers exceptional compressive strength for industrial and residential floors where a designer wants to keep the cold out but retain the strength in the concrete slab.

Target an appropriate compressive strength.
Moisture resistance is also important for belowgrade and under slab insulation since wet products provide much lower thermal resistance.
Since its discovery in 1941 styrofoam brand xps insulation has a long and rich heritage as a sustainable building product insulating to meeting core thermal moisture air and vapor performance requirements through its rigid foam board technology.
For the floors of industrial.
The side by side insulation comparison highlighted previously found the eps retained 94 of its specified r value while the xps lost nearly half of its insulating capability over the 15 years the materials.
Below grade under slab with foamular xps insulation.
It helps make effective use of the thermal mass of the concrete slab rather than repeatedly warming it and allowing it to cool.
