The new PEX Aluminum PEX line, RadiantPEX-AL, is a multilayer pipe consisting of an inner core and outer layer of high temperature-resistant polyethylene with an aluminum core. The aluminum core prevents oxygen and gases from permeating into the pipe, making it noncorrosive. The pipe can be used as supply and return piping to manifolds, fan coils, baseboards, and radiators. The pipe holds its shape and is flexible enough to bend around obstacles without the use of fittings. According to the manufacturer, RadiantPEX-AL doesn't expand like PEX, so it creates less noise in a staple-up application. It can be used with or without plates.
