ABZ Sweep are now approved installers of Eldfast

Eldfast is a UK manufactured ceramic chimney lining system designed for open and inset fires.

The name “Eldfast” in Swedish means “Fireproof” or “Incombustible” and hold this is the only system to be fully fireproof.

The qualities of the material not only retain the flue cross section, but also strengthen the chimney while helping to improve the draught. As the system is not modular, but parged onto the walls of the chimney it can also cope with fluctuations in internal size of the chimney and fill in missing mortar and damaged brickwork.

The strength of the material and resistance to heat and thermal shock makes it the only system on the market that is still guaranteed following a soot / chimney fire.
