Why is the anti-oxidant barrier in PEX tubing important?

COMAP PEX tubing with anti-oxidant barrier is recommended for heating and under-floor heating installations.
The anti-oxidant barrier, made of a layer of EVOH (ethylene vinyl alcohol), prevents oxygen from entering. It also limits the formation of slime in the system, and promotes long tube life in installations.
In addition, the barrier makes the tube more flexible, which means it's easier to install — particularly in under-floor heating.
