I am seeing flexible chimney liner installation videos on the internet. They have an insulation sleeve. The dealer where I am shopping for a wood stove says I do not need insulation around the chimney liner. Won't the flue cool down too rapidly if it's not insulated?

Answer:Use of insulation is recommended in all liner installation for maximum performance of the stove, however there is one scenario when it is not needed. If your chimney is located on an inside wall and nearly all of the chimney passes through the interior of the building envelope, you can get away without insulation.
