Insulated ducting, is designed to protect water pipes from frost outside the thermal envelope of a building, where water pipes cannot be laid at the prescribed depth (>750mm + <1350mm)
For either standard PE or barrier pipe of either 25 or 32mm diameter.
e.g. over rock, foundations, ditches, tree roots or overland for “temporary” services.
