Vulcan are approved installers of the Eldfast ceramic chimney lining system which is considered suitable for all fuels, easy to install, and resistant to high temperatures. Established over 25 years, Eldfast lives up to its name which, in Swedish, means ‘fireproof’.
Eldfast flue liners are guaranteed to withstand a chimney fire, saving you money on replacement chimney linings and giving you peace of mind. It is suitable for all chimneys, has a 50-60 year life expectancy and carries a 25 year guarantee, even in the event of a chimney fire.
Stronger and more resilient to acid attack and high temperatures including thermal shock than alternative solutions, Eldfast comprises two elements: a refractory ceramic aggregate powder and a powder bonding agent. Together, they create a thick slurry which forms an adhesive when applied under pressure.
Why Eldfast chimney linings are different:
- Maintains the internal space of your chimney flue
Traditionally, flue lining involved inserting an inflatable ‘sausage’ into the flue and filling it with concrete, leaving a small, round hole in the middle of the flue. If the fireplace is still in use, the lack of space within the flue can cause smoke to travel back down the chimney, creating an unpleasant atmosphere and covering furniture in a layer of soot. Eldfast flexible flue liners are drawn through the chimney to leave a 4mm thick layer on the face of your flue. Using Eldfast does not reduce chimney size but preserves the cross sectional area due to only requiring a 4-5mm coating.
- No disturbance or damage to your brickwork
Many other in-situ flue liners require bricks to be moved, extending the installation process. However, Eldfast flue lining is drawn through the flue using a plug so there is no need to break into the flue or remove any brickwork. In fact, once in place, it provides structural support, setting like steel when cured Eldfast supports the construction of the chimney.
- Heat resistant – acts as an insulator
Eldfast ceramic lining is more resistant to heat than other chimney lining materials, acting as an insulator, maintaining the heat of the gases passing through it and reducing the risk of condensates. This is particularly useful for homes with thatched roofs, which can lower the temperature of the gases still further.
- Not damaged by high temperatures
A chimney fire can reach temperatures of over 1000° While other flue linings can be damaged by extreme temperatures, Eldfast’s ceramic lining shows no deterioration at temperatures of almost 2000° Celsius. In fact, high temperatures only serve to vitrify this ceramic chimney lining and make it even stronger.
