Triple Lock Construction
Twinflex is constructed from 2 single strip stainless steel and locked in 3 planes. This gives maximum joint integrity and allows even weight and load distribution throughout the entire length of the installation.
Twinflex is built with high performance 316 or 904 Stainless steel. The smooth inner bore allows optimum passage of flue gases and draining of condensates.
The Twinflex is simply superior. The unique large overlap of the joint formed by the inner skin protects against acid penetration. On close inspection you’ll find some liners on the market with minimal or non existent overlaps.
