Chimney Liners & Kits
Chimney Liners are important for many reasons. Most importantly, they protect the house from heat transfer to combustibles. Whether you need a liner for a stove, fireplace or insert, Lindemann Chimney has the right option. Aluminum and stainless steel liners both come with a manufacturer’s warranty. Smart-flex liner is one of our most durable lining systems. It can be used to reline existing chimneys or in new construction. It’s a flexible liner featuring corrugated construction allowing it to both expand and contract during heat up and cool down periods. Liner kits are also available and come complete with instructions. Contact us at 1-800-722-7230 of you have any questions.
