I have two questions:
1: Is this 1/2-inch thickness?
2. I have a Duraflex 304 liner, 6-inch diameter. What is the recommended insulation? It says flexwrap is okay in the manual.

Answer:This is indeed 1/2-inch thick insulation and can be used with most brands of flexible 304 and 316 liners, including the Duraflex liner that you have. We commonly sell the HomeSaver product to go with the Duraflex brand.

What is the purpose of the HomeSaver UltraPro Chimney Liner Insulation Kit and why would I use it?
By Kevin E. on November 17, 2014
Answer:The insulation kit is designed to, as you might guess, insulate the reline components in your chimney. Chimney reline pipe is relatively thin and to ensure that the flue gases retain their heat and buoyancy (which are required for healthy draft), an insulation kit is recommended. This is especially true if the masonry chimney is grossly over sized in comparison to the reline pipe and if the chimney is located outside the building envelope.

I ran 6" stainless steel flex liner up my masonry (clay-lined) 12" chimney 8 years ago when I first installed it. Never used or heard of "Chimney liner insulation". Whats the function or purpose of its use? By the way my liner is doing just fine,I clean & inspect it annually.

Answer:Flue liner insulation is a good idea, but not necessary for all installations. In the event that you are lining a greatly oversize flue or your masonry chimney is on an outside wall, the insulation helps to keep the flue gases in the liner warm and prevent unwanted smoke spillage or backpuffing into the room.
In some cases, the chimney flue will be so cold that the stove will not establish a good draft or will build up excessive amounts of creosote in a short time, leading to a chimney fire.

How much larger in diameter will my 6 inch stainless steel liner be after I install this?
By Will M. on October 10, 2016
Answer:Using this product will add 1 inch to the outside dimension of your flexible liner. If the outer diameter of your 6 inch liner is 1/2 inch larger than the inner diameter, this would make the overall outside diameter of your liner 7 1/2 inches.

I am shopping for FlexLiner insulation. I'd like to know the thickness and the composition of the Home saver UltraPro Insulation kit. Another manufacturer states theirs is an eight-pound density ceramic blanket with zero clearance to combustibles. Is your product comparable?
on November 9, 2012
Answer:This liner insulation is also 8 lbs density, made with ceramic wool and measures between 1/2" and 3/4" thick. It has zero clearance in a masonry chimney.
