Installing a stainless steel chimney liner is an easy and economical way to repair an unsafe, deteriorated, or inefficient chimney. You can install a chimney liner fairly easily after reading our instructions (see Fitting a flexible liner) and you can do the job with regular household tools.
A flexible flue liner should be installed to reduce the chance of a carbon monoxide leak, chimney fire, and creosote build-up. A chimney liner also improves the energy efficiency of the appliance and makes fireplace maintenance easier.

Single wall pipes
We supply single-wall pipes in two styles. We offer a black enamel flue pipe in a standard matt finish. Stainless steel flue pipes can also be used inside an existing chimney. Whether you decide on our black enamel or stainless steel flue pipes, they fit easily together.
Our stove pipe is a matt black, single-wall stove pipe. Its enamelled interior and exterior ensure the durability of the colour and increase its resistance to high temperatures and condensation. At 1 mm steel thickness, it can be easily cut to the required size using fine-grain grinding disks.
The single wall flue pipe is the standard for venting heating stoves. A black stovepipe is used to vent the stoves exhaust out of the living space and into a chimney liner or chimney system. This is commonly called a "connector pipe".
Suitable for use as a stove connection to a chimney or liner, for domestic and commercial heating appliances.
Twin wall flues for new chimneys
A twin wall flue system allows a stove to be installed practically anywhere in the house. Whether it's in an existing property or a new house, an isolated twin wall flue pipe lets you install a new chimney that is safe, effective and easy to fit.

Twin wall systems can be constructed to produce a safe chimney system for your appliance.
Twin wall flue pipes are suitable for the creation of both indoor and outdoor flues and they can be used to pass through roofs and floors. Our double-wall flues are suitable for use with wood, coal, gas and oil appliances.
Our Twin wall flue system is also perfect for biomass boiler installations. For twin wall pipes, ceramic wool of the highest quality is used as insulation material. Our pipes are supplied with the necessary locking bands free of charge!

Frequently asked questions
-
What is the difference between a chimney and a flue?
A flue is the channel, pipe, or tube through which gases and smoke travel from the fireplace to the outside. A chimney is, on the other hand, in its simplest definition, the housing that encases the flue.
There’s a misconception that masonry chimneys are simply made of brick. This isn’t true. The uneven and porous surface of brick provides a space for combustion byproducts to accumulate. This is a major fire hazard. Therefore chimneys are lined with a flue, so the smoke passes over a smooth surface that helps prevent excessive accumulation of combustion byproducts and minimizes the chance of fire. Read our full article on chimneys and flues here. -
What does open flue mean?
An open flue typically consists of a pipe to carry combustion gases from the fireplace, whilst fresh air enters the fireplace via the casing. So for safe operation, additional air vents are required in the room where the appliance is installed to re-supply fresh air.
-
Does a chimney need a liner?
If you are installing a chimney in a new build property and you want to use it for an open fire, wood-burning stove or gas fire, then the chimney does need to be lined to comply with document J of current building regulations. In an older property, your chimney doesn’t have to be lined to meet building regulations. An inspection by a chimney professional will tell you if you need to have it lined for safety purposes.
-
How does a chimney work?
Chimneys operate on the principle that hot air rises above cold air. Hot exhaust gases and ash are lighter in weight than cold outdoor air. The flue directs exhaust from these lighter gases from a fireplace upward to vent outdoors into the atmosphere. Additional air vents are required in the room where the appliance is installed to re-supply fresh air.
