Do I Need To Insulate My Chimney Liner? 

This is a question asked quite a bit. Is it necessary to insulate my chimney liner? If you are in the market for a stove or fireplace or have one, you may be asking this question. We will tackle it for you. There is no legal reason that insulation is mandated for chimney liners. However, many experts suggest that insulation around your chimney can be beneficial.

Why Would I Consider a Chimney Liner?

• Insulation is meant to keep the inside of the liner warm, which helps with the smoke draft. When the flue is warm smoke and fire travel right up. With a cold flue smoke and fire struggle to exit the chimney causing a draft and smoke. 
• When wood is burned in your fireplace, creosote is created. A hot burning fire will minimize this. Insulation is an excellent choice if your chimney is located on an outer wall. 
• Your chimney is bigger than the flue. If there is space between the chimney and the flue air will cause a cool down of the flue. Insulation will bridge that gap and create a barrier to keep the flue warm.
• The chimney stack is too tall. When a chimney is too tall it will stay cool. Fire takes a while to get up the chimney and out. Keeping the flue warm will encourage the fire and smoke to exit the chimney. 

Types Of Insulation: There are two main types of insulation used for chimney flues. Northeastern Chimney Inc. can offer these two types.

• Insulation blanket – A blanket made out of a high-density material, alkaline earth silicate. This blanket is wrapped around the flue, all the way to the top. It keeps the flue warm allowing the fire and smoke to easily escape the chimney. 
• Vermiculite chimney insulation mix – This mixture is vermiculite and Portland cement. It is poured down your chimney between the flue and chimney. This is a great option for chimneys that are narrow and cannot accommodate a blanket. 

Chimney liner insulation can be very beneficial in efficiency with your fireplace or stove. By keeping your liner insulated the warmth is captured in. Keeping your chimney hot allows the warm air to circulate into your home.
