Product Description

Single Wall Liners

• Made from corrosion-resistant 316L stainless steel.
• Leak resistant construction due to continuous weld (Wonderflex) or dovetail folded seam (Triplelock).
• Highest corrosion resistance.
• Deep corrugations for high crush resistance and better flexibility when installing.
• Strong seam construction resists the rigours of pulling the liner into place during construction.

Twin Wall Liner

• Both inner and outer layers made from corrosion-resistant 316L stainless steel. 904L stainless steel is also available as an option for the extreme conditions found with appliances like slumbering stoves.
• Corrugated outer skin for high crush resistance.
• Smooth inner skin resists corrosive attack due to easy drain down of condensate, less opportunity for soot collection and smooth surface for ease of sweeping.
• Inner skin remains overlapping to protect the joint from corrosion penetration even at minimum bending radius.
• Inner skin remains smooth and protective even after the rigours of installation.
