Our INOX System Specifications
Schiedel ICS (Insulated Chimney System)
The universal workhorse for new builds and retrofits, suitable for all standard fuels. Its twin-wall construction with high-density Superwool™ insulation maintains high flue gas temperatures, improving draught and minimizing condensation. The simple push-fit jointing system dramatically reduces on-site labor hours, lowering project costs. As the only system to pass the GASTEC corrosion test, its 316L stainless steel liner guarantees exceptional durability.
Schiedel ICID Plus
Engineered for modern, high-efficiency heating like pellet stoves, biomass, and condensing boilers. Its advanced design allows the inner liner to expand and contract independently, ensuring structural integrity even under extreme thermal stress—a critical safety feature for integrated building systems. The secure twist-lock jointing system provides exceptional rigidity, and the system is ready for positive pressure applications, making it a future-proof investment. The ICID Plus is backed by a comprehensive Ten Year Guarantee.
Schiedel TecnoFlex
The premier problem-solver for relining existing masonry chimneys with difficult bends and offsets. Its twin-skin flexible design allows installers to navigate challenging flue paths without costly demolition. The exceptionally smooth inner wall improves condensate drain-down and reduces soot buildup, while the engineered interlocking joint ensures the liner will not separate during installation—saving time and ensuring a reliable outcome for renovation professionals. Available in high-grade 316L or 904L stainless steel and backed by a Ten Year Guarantee.
