Lightweight and ultra-flexible, Fastwarm EVOH Pert barrier pipe is the ideal solution for large installations where the absence of a metal layer makes it less taxing to bend and install than Pert-Al-Pert pipe without sacrificing performance. Our 16mm EVOH pert pipe is manufactured to ISO9001 standards ensuring outstanding performance & reliability in all types of warm water underfloor heating systems. EVOH PE-RT pipe consists of 3 layers which is made up of an oxygen barrier (EVOH), a layer of adhesive, and an inner layer of pert pipe. The oxygen diffusion barrier encases the inner layer of PE-RT pipe completely to prevent the entry of oxygen into the heating system through the pipe. The tough outer layer is designed to withstand the demands of a worksite ensuring the oxygen barrier remains intact, which reduces the risk of corrosion within the heating system.
