Insulation - Blanket Wrap or Pour Down Mix

Chimney liner insulation kits help ensure safety and efficiency for stainless steel flex chimney liners. Insulation also reduces the build up of creosol and helps your chimney stay cleaner longer. Rockford has two options for you to pick from when considering chimney liner insulation: Super Wrap Blanket Kits and EverGuard Pour-Down Insulation Mix.

Chimney Insulation Mix

Everguard insulation mix is a ready mix, vermiculite based insulation material. Just mix with 4-7 gallons of water per bag and you are ready to go. This pour-down insulator is an alternative insulating method to using Super Wrap. Great for tight fitted lining jobs or insulating after a liner has been installed.It's easy to work with. It will fill dangerous voids and cracks in the masonry work while strengthening the chimney walls.

It cures into a lightweight, semi hard mass that supports a liner in the chimney and forms a thermal barrier that keeps the flue gases warm.

This product adds performance to your liner and is very durable. It is UL listed for zero clearance to combustibles. The mix eliminates moisture buildup between the liner and the chimney structure. It is accepted by building code officials, and what's better is that it can also be removed.

One bag weighs 45 lbs and covers 2.5 cubic feet. See insulation mix instructions.

Note: A chimney balloon is the best solution to stop the insulation mix from leaking into your fireplace or down into your cleanout door at the base of your chimney. For example, inflating a chimney balloon inside your chimney just below the thimble will prevent the insulation mix from filling up the flue cavity below the thimble, which would seal off access through the cleanout door. The chimney balloon should be removed, once the insulation mix has cured, before a fire is lit in the chimney.

When do I need to insulate?
To maintain efficiency, safety, and to significantly reduce formation of creosol you will need our 1/2" Super Wrap blanket insulation kit or our Ever Guard insulation mix. This can help ensure the safety and efficiency of your stainless steel flex chimney liner. Adding stainless steel flex liner insulation can also help reduce the buildup of creosol as well.

Why insulate?
It is strongly advised that you do insulate. When you install your liner with the proper chimney insulation (chimney liner) your reline job creates an environment that allows your appliance to be as efficient and safe as possible. Plus your insurance company will love you for it. An insulated chimney liner has a better draft and stays cleaner longer, which is a benefit to any stainless steel flex chimney liner.
