ThermoFin Heat Transfer Plates
ThermoFin is a rigid, extruded aluminum plate designed to facilitate heat transfer in radiant floors. Cross-linked polyethylene (PEX) tubing is held securely in the patented snap channel, without additional fasteners. This tight fit eliminates expansion noises and provides excellent heat transfer.
ThermoFin plates are available in two configurations. All plates are sold in boxes of 20 pieces.
