The ExtraFlex lining system is designed to be installed inside masonry chimneys. ExtraFlex liners are used to vent the flue gases and combustion byproducts produced by appliances that burn oil, gas, or solid fuels.

In Canada they are tested to ULC S635 and are to be installed in masonry chimneys.

The ExtraFlex Stainless Steel Flexible Chimney liner is designed to reline existing chimneys or to be used as a liner in new construction. Manufactured with the highest quality, mill certified alloy. ExtraFlex Stainless Steel Flexible Chimney Liner has a high acid fighting capability. Listed by UL Laboratories to UL 1777 & ULC S635 standards for zero clearance installation. ExtraFlex can be used to vent wood, wood pellet, coal, noncondensing gas and oil, making it the choice for venting all standard efficiency installations. UL listed ExtraFlex is available in 3" to 12" diameters (13" above is not listed) to cover a wide range of requirements found in the field today.

The unique manufacturing systems used to make ExtraFlex utilizes a continuous strip of stainless steel, 7-ply interlocked and crimped to produce a gas and water tight lining system of superior strength and durability. ExtraFlex can be curved to go around offsets in chimneys and can be factory ovalized to custom sizes to fit most any installation requirement. Unless specified by the manufacturer, the liner is not to be field ovalized. The corrugated construction allows for expansion & contraction during the heat-up & cool-down periods, which removes any stresses on the system.

ExtraFlex can be insulated with either a vermiculite based poured insulation or with a foil-faced ceramic wool blanket to meet UL 1777 & ULC S635 standards for chimney exteriors with zero clearance to combustibles.
