  • If you will be using a concrete slab or basement slab, it is important to utilize the exterior perimeter insulation, as well as under slab insulation. The tubing is attached to a 6×6 welded wire mesh using plastic or wire ties. The tubing inches on center should be determined by a calculated heat loss. Concrete Slab-On-Grade Application:
  • For a 12×12 exterior slab …I advise 4″ of compacted stone sub-grade, wire mesh, no fiber, low slump concrete, air entrained, 3,000 psi mix, and soft cuts creating a four-square pattern. The slab will definitely crack on the four-square lines but you will have done all you could. The rest is up to mother nature. Good luck.

  • This is why you use slab-on-grade exposed floor PERIMETER (and not the floor AREA) when doing the building heat loss analysis. So for unheated slab-on-grade Ti=70 and To=0 you get 0.125(Ti-To) or 8.75 MINIMUM R-value. For 100 deg F heated slab-on-grade you get 0.125 (100-0) or 12.5 MINIMUM R-value.
