What is a flexi liner?

Flexi liners or flexible flue liners are used to line an existing chimney. They are made from corrugated steel and can be bent to go round corners inside the existing chimney. They are usually fitted by removing the chimney pot and sliding the liner down the existing flue way.

How much do I need?

For a normal 2 storey house, an 8-meter liner kit will normally suffice. however flexi liner should not be joined so its best to purchase more than you need. A rope can normally be passed down the chimney and marked off to measure the length required. If that’s not practical a laser measuring device can sometimes be used to get an approx length.

Gloves should always be worn when handing flexi liners as they are sharp and can cause injury if not handled correctly. It is also worth mentioning that these liners have to be fitted in the correct orientation.
