If you're converting your factory-built or masonry chimney to a direct vent system, you're going to need this Dura-Vent DirectVent Pro 4-Inch x 35-Foot Aluminum Chimney Liner. This liner not only makes the conversion relatively simple and completely secure, but it's also built to withstand the heat and rigors of frequent and extended use.
This handy liner is constructed with two layers of flexible aluminum for great structural integrity combined with easier-than-you'd-think installation. Each aluminum layer is .01 inches thick, which is thin enough to maintain flexibility, but thick enough to provide years of worry-free function. Many homeowners choose to make their direct vent conversion a relatively simple affair using this DirectVent Pro Aluminum Chimney Liner.
