What is Pex?

PEX is composed of high-density polyethylene that undergoes a physically or chemically induced molecular change. This change creates polymer chains which are linked to form a three dimensional network producing a thermoplastic product. This creates a product that is stable at higher temps yet remains flexible and chemically resistent to damage.

Why use O2 barrier pipe (EVOH Pipe)?

The O2 barrier keeps the oxygen from corroding your hydronic systems ferrous materials such as you would find in circulation pumps and boilers. It cost a bit more than non-barrier PEX, however it's well worth the extra cost. All residential and light commercial radiant floor systems should be installed with O2 Barrier pipe.

What is Pex-al-Pex?

PEX-AL-PEX pipes, or PEX/Aluminum/PEX, are made of a layer of aluminum sandwiched between two layers of PEX. The metal layer serves as an oxygen barrier, same as EVOH pipe. It also maintains its shape when bent into curves, making installation much quicker and easier.
