Flexible and Fixed Twin Wall


Used to reline existing chimney

Flexible steel liners are supplied in various grades relating to their quality and length of guarantee. Document J of the Building Regulations requires that a flexible flue liner can only be installed completely enclosed inside a masonry chimney. A non masonry enclosure such as timber or plasterboard boxing is not acceptable. The type of flexible flue liner permitted depends upon the appliance and fuel type.

Fixed Twin Wall

Used when there is no chimney

Don't have a chimney? You can still enjoy the beauty and efficiency of a multi fuel stove. Twin wall flue systems allow a stove to be installed on any suitable external wall or in another position within the home subject to survey and suitability. They can offer you extra flexibility on the positioning of your stove. All twin wall chimney systems must be installed to comply with Document J of the Building Regulations in England and Wales and part F of the Building Regulations in Scotland, as well as to the flue manufacturer's installation instructions.


How often should flues be swept?

 It is recommended that chimneys serving solid fuel appliances be swept and maintained as frequently as necessary but at least once a year. We will also carry out an inspection of the flue, using CCTV equipment if required to check the integrity of the liner and components. Regular maintenance by a qualified sweep with issue of certificate will almost certainly be a requirement of your flue and stove guarantees as well as being an important safety measure against chimney fires and carbon monoxide poisoning.
