DuraVent DVL is a double-wall interior stovepipe for connecting woodstoves to a manufactured chimney.

Simpson DVL's double air insulated design reduces clearances to combustibles from 18" to 6" to walls, and 8" to ceiling. The Simpson DVL system improves stove performance by maintaining high flue gas temperatures for a strong, steady draft. Because the inner wall is stainless steel, the flue heats up faster and stays hot longer, minimizing the formation of creosote.
The DVL system ensures safety and dependability with the same life expectancy as the chimney. Adjustable lengths eliminate the need for cutting and crimping, making installation fast and easy. Simpson DVL carries a limited lifetime warranty and is UL and ULC S641 listed. DVL is available in 6" - 8" sizes.
