Why Double Wall? Double-wall, air-insulated design reduces clearances to combustibles from 18" to 6" to walls and 8" to ceilings, the closest clearance to a wall of any connector pipe. Double wall stove pipe is designed to increase wood stove efficiency and improve the overall performance of the wood stove by maintaining high flue gas temperatures for a strong steady draft. The inner wall of double wall pipe is designed to heat up faster, stay hotter longer and minimize the formation of creosote.
