Flue Liners:

Liners built to form a flue, in a chimney breast and chimney, which resists the products of combustion and minimise maintenance. Liners, for domestic flues, manufactured in fireclay or refractory concrete are 200mm in diameter with ends formed as a socket; available in a variety of lengths and bends. Gas flue block systems are designed so that they may be built flush to the surface in internal walls.
