What is a Twin wall insulated Stainless Steel flue system?

This system is designed for homes without a chimney or where the chimney stack has been partially removed. They are generally made from sheet stainless steel encasing an insulation layer that keeps the flue gasses hot as the rise through the pipe sections.

Twin wall pipes for log burners can be purchased in a variety of diameters (normally 6″) and clip together with a purpose made locking band. Plain pipes being shiny stainless steel do not fit with many homes and we recommend choosing a colour from our colour chart so that the flue system blends in with your existing guttering or pipework.
