30 meter lengths of 8″ diameter 316 twinwall flexible flue chimney liner are predominantly bought by companies or individuals operating in the trade. Existing trade customers who buy this product consist of chimney specialists, stove fitters / installers, builder merchant, hardware store and stove and fireplace shops.

Tradesmen and the professionals listed above will cut a 30 meter length of 8″ diameter 316 twinwall flexible flue chimney liner to the appropriate size and use it to reline a chimney flue connected to a fireplace where the original chimney flue was damaged, perhaps in a chimney fire.
