Chimneys : A Look Back in History

Stainless Steel Chimney Liners Are Excellent, But…

Stainless Steel Tubes are corrosion proof for 10-15 years but it is impossible to insert them into a long chimney with bends (often around fireplaces) without breaking open the inside walls of a home or business. This problem is often found in multi family dwellings such as the Chimneys in Brownstones of Brooklyn and Manhattan in our particular service area. Additionally there is the problem of tile knocking. this is the process of having to remove the existing terracotta clay chimney systems found in most homes in Long Island. This is a labor intensive process that is often required when trying to fit a larger stainless steel liner in a pre-existing smaller terracotta chimney flue. In many cases the Furanflex installation is flexible enough to fit right into the pre-existing terracotta chimney.

The FuranFlex Design

The internal layer facilitates installation. It is a thin walled (100-150 microns) plastic hose made up of a mixture of thermoplastic components.



The intermediate composite layer is the heat, flame and corrosion resistant structural material of the FuranFlex chimney liner tube. Composite means resin of high solidity reinforced with thin glass fibers. One Square meter of the wall structure of the FuranFlex liner tube contains 3,000,000 meters of factory specified fibers.



The external layer is a thin fabric woven from synthetic fiber. Its function is to protect the composite layer and to insure the exact diameter of the chimney tube. It’s other function is to form a homogeneous external surface.
