K-FLEX EVOH
K-FLEX EVOH multilayer pipes are designed primarily for hydronic underfloor heating and compatible radiant heating systems. Their flexible, lightweight construction enables continuous circuits with fewer concealed joints and allows easy installation with studded or flat insulation panels, clips and fixing rails.
The integrated EVOH oxygen barrier limits oxygen ingress, helping protect manifolds, pumps, valves and heat generators against corrosion in closed-loop systems.
