We offer a double - skinned flexible flue liner, which we offer in a 316L grade or a 904L grade; and are used to line a masonry chimney. The flexible liners that we use are HETAS and CE approved. Our flexible liners are suitable for burning both wood and smokeless fuels. The majority of woodburning and multifuel appliances most commonly require a 5 or 6 inch flexible flue liner; although alternative sizes are available and can be sourced if the appliance manufacturer requires them. 

Our 316L grade flexible liners are more commonly installed for solely wood burning appliances; whereas our 904L grade liners are more commonly manufactured to withstand higher burning temperatures that are seen in multifuel appliances where smokeless fuel is burned.
