A lightweight pipe that can be used in all types of warm water underfloor heating installations. Our ultra flexible 16mm EVOH pert pipe is manufactured to ISO9001 standards ensuring outstanding performance & reliability. 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.
