Abstract
A carbon steel (or other type) chimney liner is provided with an inner membrane of relatively light gauge steel which is highly resistant to corrosion and which is constructed to accommodate thermal expansion in any direction independent of the structure to which it is attached. The membrane and chimney liner include an annular space therebetween which is placed under a vacuum.
