Hi-Therm PERT2Gen PERT Type II EVOH 16x2.0 pipe is A flexible three-layer PERT Type II pipe with EVOH oxygen barrier for water underfloor heating systems.
The EVOH oxygen barrier reduces oxygen diffusion into the heating circuit, helping protect metal components from corrosion and extending system service life.
| Parameter | Value |

Installation: installation should be carried out by qualified personnel at an ambient temperature of at least +10°C. Press fittings or compression fittings suitable for 2.0 mm wall thickness are recommended.
Before covering the underfloor heating circuit, hydraulic leak testing must be completed. During screed pouring, the pipe should remain under 0.3 MPa pressure; the minimum screed layer above the pipe is 3 cm.
Technical data is based on the Hi-Therm Pipe Spain 2025 catalog.
