Jasy reviewed our product and he mentioned that Flueblocker is a chimney insulator to stop cold drafts, insects, and odor from getting in your house when you’re not using your fireplace.
And this I made out of thick layers of wool from Herdwick sheep which is a durable, natural insulator. It comes in round or rectangular shapes and a variety of sizes.
And depending on your chimney, you can use this outside your damper or inside the flue pipe and all you have to do is to push it up in the chimney when you’re not using it. It has a reminder to remove it before you start a fire.
