When purchasing a stainless-steel chimney liner, you may wonder whether you need to insulate it. There are many benefits to insulating your stainless-steel chimney liner. Our technicians will be happy to talk with you about all the options that may benefit you. Here are a few.

Benefits of Insulation

Insulating the chimney liner will allow the flue a quicker heat-up time as well as higher temperatures.
With a liner, you won’t have to worry about inadequate drafts. A liner that is insulated maintains a hotter draft, so it exits the chimney quicker. This is crucial for efficient combustion.
Creosote won’t form as quickly due to hot combustion gases.
Prevents Condensation. Insulation keeps flue gases warm. This reduces condensation, which may lead to moisture problems, rust, and corrosion.
Extends the life of the chimney. Insulation helps prevent the chimney liner and its surrounding structure. This helps to protect from temperature fluctuation and condensation.

What Type Of Insulation Can I Choose From?

Insulation blanket

It is made of a high-density insulation material. The material is called alkaline earth silicate. The blanket is wrapped around the complete length of the liner. This option is not always ideal, as there may not be enough clearance between the chimney and the liner to encompass it. A fiberglass insulation material cannot sustain the high heat from your chimney and should not be used as an insulation.

Vermiculite Chimney Insulation Mix

Our technicians will mix the vermiculite with water to a pourable consistency. Then the mixture is poured into the void around the liner, usually from the top. This while making sure of even distribution and filling all gaps. The mixture will need to cure for about 24-48 hours to solidify. Our technicians will finalize by ensuring that the space around the liner is filled.
