With so many different kinds of PEX to choose from, how do you make a decision? The answer comes down to what your PEX project will entail. Is the PEX tubing going to be used for a radiant heat application or an open system? Is the PEX expected to withstand high temperatures? If you are looking for the perfect type of PEX for a high-temperature system, such as baseboard heat, PEX-AL-PEX is the perfect choice. PEX-AL-PEX consists of a layer of PEX, a layer of aluminum, and another layer of PEX. PEX-AL-PEX is also considered more convenient than other types of PEX is because it tends to hold its shape once you bend it, so it does not require fastening like more traditional forms of PEX. It additionally boasts an oxygen barrier, which assures that no oxygen enters the heating system. This is extremely important in heating applications because the presence of oxygen can rust and corrode the system's components.
