FlexPlate™ flexible, graphite plates install 40% faster than aluminum plates with 50% higher thermal conductivity! Better utilize high efficiency, low temperature heat sources such as condensing boilers, geothermal or solar. These heat transfer plates are made using a patented, highly conductive graphite material. Used in underfloor, wall, ceiling or above floor applications, FlexPlate™s require lower water temperatures and produce more uniform floor temperatures than extruded aluminum plates. FlexPlates are lightweight, flexible, cut easily with scissors or a utility knife, easy to staple and don't have any sharp edges that require grinding. For 1/2 in RadiantPEX+/RadiantPERT™ or RadiantPEX-AL™. Measures 6 in W x 4 ft L.
