- Product Info
The Roth Radiant Floor Panel System is an easily assembled PEX tubing track system that allows simple installation of hydronic radiant floor heating over an existing subfloor. The system is designed around a 90 psi (6.3 kg/ cm2) high density polystyrene foam field panel with a bonded 24 ga. aluminum sheet on top.
The foam provides thermal insulation below the panel and the aluminum provides even heat distribution focused directly at the finished floor material. The low profile of this product allows for easy retrofit and the light weight makes it easy to use in new construction. The 2' x 4' (61 cm x 122 cm) field panels make installation faster than other available products. The field panels have tracks that allow the tubing to be snapped in (no adhesive is required) on either 6" (15.25 cm) or 12" (30.5 cm) centers.
Radius panels for return bends and twin tube transition panels, to route tubing to the heated area, are included with each box of the Floor Panel System. Additional radius panels are available separately, if needed. The Floor Panel System for 3/8" PEX tubing is 3/4" (1.9 cm) thick and provides an approximate downward insulation value of R=3.7. The Floor Panel System for 1/2" PEX tubing is 1" (2.5 cm) and provides an approximate downward insulation value of R=4.5.
The full-face aluminum sheet on the field panel provides heating characteristics similar to a lightweight concrete overpour, but at lower fluid temperatures and with faster pick-up times
