Material Options

Material prices below are national averages; availability in Boise may shift costs slightly.

Material	Cost/Unit	Pros	Cons	Best For
PEX Tubing (Standard)	$0.50-$1.00/linear ft	Flexible, corrosion-resistant, easy to route, 50+ year lifespan	Cannot be exposed to UV light, needs proper oxygen barrier	Most residential hydronic radiant installationsFlexible, corrosion-resistant, easy to route, 50+ year lifespan
PEX-AL-PEX (Aluminum Layer)	$1.00-$2.00/linear ft	Holds shape after bending, built-in oxygen barrier, lower expansion	More expensive, less flexible than standard PEX, fewer fitting options	Tight routing situations and high-oxygen-sensitivity systemsHolds shape after bending, built-in oxygen barrier, lower expansion
Thin-Slab Overpour (Gypcrete)	$3-$6/sq ft installed	Excellent thermal mass, even heat distribution, quiet	Adds 1-1.5 inches of floor height, heavy, longer cure time	New construction or major renovations where floor height change is acceptableExcellent thermal mass, even heat distribution, quiet
Aluminum Transfer Plates (Staple-Up)	$2-$4/sq ft	No floor height change, works from below, faster install	Slightly less even heating, requires accessible floor joists	Retrofits with accessible basements or crawlspacesNo floor height change, works from below, faster install
Structured Insulation Panels	$4-$8/sq ft	Pre-grooved for tubing, insulation built in, fast installation	Higher material cost, adds some floor height, limited to certain tubing sizes	Retrofit over existing subfloor where access from below is not possiblePre-grooved for tubing, insulation built in, fast installation
