I am planning on installing a fireplace insert into a wood burning fireplace. I will be using one of your Napoleon flex liners, but I don't know how to seal and insulate the space. Do you sell insulation (sheets, rolls, or expanding foam) that will fit my needs? I have a 12 x 12 chimney right now that I will be running a 3" flexible liner through up to the chimney exit.

Answer:Because gas appliances do not typically suffer the drafting issues associated with wood burning inserts, insulation is not usually used around the liner itself. To stop cold air from sinking down the chimney and into the room, unfaced fiberglass insulation is usually rolled into tight sections and packed around the liner where it passes through the damper area. The insulation is not of any special make and standard fiberglass will work well.

I have a chimney that is only 7 years old and in great shape. I want to place a wood stove in my fireplace. Can you tell me is this flexible compressed aluminum gas liner kit all I need? Also, do you have some type of sheet metal to close the damper in the fireplace? Since the fireplace damper will have to stay open to let the pipe pass through.

No this kit is for a GAS unit not a wood unit. If you are looking to reline your current wood fireplace chimney you would need a wood relining kit
the preferred method is to remove the damper or block it into the open position.
are usually made to fit each application and are fabricated individually. Just be sure to use non-combustible material.
