A Guide to Chimney Lining Systems
Chimney lining is becoming an increasingly popular way to prevent the risk of carbon monoxide poisoning and improve energy efficiency in homes throughout the UK. Because a lot of chimneys are currently lined with lime mortar, they’re susceptible to decay with prolonged use, which can result in problems with the performance of your fireplace. Getting new chimney lining will help you avoid these problems and ensure that your home or building is completely compliant with building regulation standards. When looking for a new type of lining for your chimney, it’s important to know what options are available and what the advantages and disadvantages of each are.
Types of chimney lining systems Below are the three main types of chimney lining solutions that are used today -
Eldfast
Eldfast is a very popular choice of chimney lining. Manufactured in the UK and made from a ceramic aggregate powder mix and bonding agents, it’s both easy to install and fire resistant. One of the biggest benefits of using Eldfast for existing chimneys is that because it’s installed from inside the chimney flue itself, there’s no need to damage the brickwork to install it. –
Eldfast also maintains the internal space of your chimney flue, which prevents problems associated with reducing the space, such as soot coming down the flue. Overall it’s an excellent choice for almost any type of chimney.
