Avoid cheap, poor quality flue liner.

When you choose to use a flexible flue liner it becomes an essential part of your installation – responsible for channeling the noxious and hot gasses safely out of the building.

Do not compromise on your safety just because the flue liner is hidden from view, it has a very important role to play.

The popularity of wood burning stoves has led to an increase in demand for flue liner, unfortunately for the consumer this has resulted in poor quality products hitting the market.

Direct Flues only sell flue liner that is produced by manufacturers with a proven track record in the industry.

Flue liner length - get it right and don't skimp.

If your liner is not long enough for your installation there will undoubtedly be delays and disappointment (plus the additional cost of a correctly sized flue liner).

Adding an extra metre (or two) - will help ensure your installation goes ahead without delay and could save you far more than the small additional cost.
