Hi AJH1,
Thanks for getting in touch.
Hep2o barrier pipe would require insulation if installed in an area where there is a risk of freezing. The barrier layer in Hep2o barrier pipe prevents the ingress of oxygen, it is not an insulation layer.
Hope this helps, don't hesitate to be in touch if there's anything else you need to know.
Thanks, Hep2O team.
