Applications / Pre-insulated pipe / PIP with EVAL™ barrier

Pre-insulated pipe

Extend the insulation efficiency and service life of heating and cooling systems, by adding EVAL™ barrier to pre-insulated pipe.

EVAL™ EVOH is 9000x more barrier than HDPE.

Put another way, just 1mm of EVAL™ would provide the same gas barrier as a 9-metre wall of HDPE!

EVAL™ provides an effective barrier in both directions, blocking the permeation of air, and locking the PUR insulation's cell gases inside.  


PIP with EVAL™ barrier

EVAL™ adheres to the PUR insulation without any additional surface treatment, providing additional mechanical stability to the entire structure.
