The STABILE EPS line of sintered expanded polystyrene is the state-of-the-art solution for air intake and exhaust of heat pump water heaters and hybrid boilers. Thanks to its extremely low thermal conductivity ($\lambda = 0.032$ W/mK), these rigid insulated ducts eliminate the risk of leakage and condensation along the way.
Certified according to EN 17192, the system provides Class ATC 2 air tightness and can handle flow rates up to 680 m³/h. Its light weight (only 0.34 to 0.54 kg/m) and the variety of available diameters make STABILE EPS ideal for efficiently connecting indoor thermal units with the outdoor environment while maintaining the energy efficiency of the system.
