PEX-A Pipe
The Warmup PEX-A Pipe is formed as a single extrusion with an adhesive layer and EVOH oxygen barrier.
Key benefits
Oxygen barrier
Encasing the PE-Xa completely, the adhesive layer prevents oxygen entering the system via the pipework.
Easy to lay
Flexible and light, the pipe is easy to lay down.
Corrosion free
The coatings stop oxygen from entering via the pipework minimising the risk of corrosion to the system.
Recommended Pipe for Hydronic Systems
The oxygen barrier is required to prevent ingress of oxygen which will fuel corrosion within the system. The PEX-a pipe is able to withstand higher pressures, is more kink resistant and considerably more flexible than competing Pex-pipes. This means an easier installation for the installer.
The oxygen diffusion barrier encases PEX-a completely, preventing the entry of oxygen into the heating system via the pipe work. The tough outer layer is designed to withstand the rigours of surrounding workloads, ensuring that the oxygen barrier remains intact. This significantly reduces the risk of corrosion within the entire system.
PEX-a pipe is what we recommend at the heart of all our underfloor heating systems because it is strong, flexible, kink resistant and comes with our best warranties, guaranteed.
