Ceramic Fiber Insulation, 24"x15.7"x1" Thick, 2600F Fireproof Insulation Blanket for Wood Stove Baffle, Fireplace, Pellet Stove, Chimney, Furnace, Boiler, Pizza Ovens and Forge

I recently picked up this ceramic fiber insulation blanket for a DIY pizza oven project, and it’s been a great addition to my setup. The 24"x15.7"x1" size was just right for lining the dome of my oven, with a little left over after trimming. Cutting it was simple with a sharp utility knife, though I’d echo the product’s advice to wear gloves and a mask—there’s some dust when you slice it, and it can itch if it gets on your skin. The 2600°F rating is no joke. I’ve fired my oven up to around 900°F, and this blanket keeps the heat locked in where it belongs. The exterior of the oven stays cool enough to touch, which tells me the insulation is doing its job. It’s also held up well after a few uses—no signs of breaking down or charring, even with direct exposure to the firebox heat. The texture is dense but flexible, making it easy to tuck into curved spaces without tearing. On the downside, it’s a bit heavier than I expected for its size, so if you’re working on something portable, that might be a consideration. Also, while it’s advertised for a ton of uses (wood stoves, fireplaces, forges, etc.), the dimensions might limit it for larger applications unless you buy multiple pieces. For my pizza oven, though, it was spot-on. Compared to a cheaper fiberglass insulation I tried before, this ceramic blanket is leagues ahead—better heat retention and no weird smells when it gets hot. It’s not the cheapest option out there, but the quality feels worth it. I’d rate it 4 stars—knocking off a half point for the dust and weight, but rounding up because it performs so well where it counts. If you’re tackling a high-heat project, this is a reliable pick.

It worked perfectly. I didn't have to cut it any. It fit right over the top part of the oven and perfect length for the sides. Would order again.

Worked good, I had to cut it so it wasn't too thick when being used as a base gasket but the thickness was good when using it as insulation on top of the boiler. I cut it with a utility knife with new blade and it was pretty easy to do. I used a cardboard piece to make straighter cuts. Should definitely help hold the heat in the boiler as the old stuff was almost like house wall insulation.. Glad I bought the two pack as i used most of it up. Layered it for most heat retention.

I bought this to add an extra layer to my old Mr volcano forge. The product is good, but I’m not sure my forge is big enough for the extra inch of insulation😂. It is however heating up a lot faster and evenly.

I gave this 4 stars overall. It does what it’s supposed to do, but it can be a bit difficult to work with. The material tends to fall apart pretty easily, so you have to handle it carefully during installation or it can get messy. That said, I used it to replace the old insulation on my smoker, and it seemed to seal everything up really well. Once it’s in place, it performs as expected and handles the heat without any issues. Overall, a solid product that works well, just be prepared to take your time with it during install.

Works just as described

Try not to rub it. It will shed some. Once in place there is no reason for it to not be durable. Easy to cut with scissors.

I purchased Lyrufexon Ceramic Fiber Insulation for it's high temp and fireproof ratings. I needed it to seal the area around my furnace vent pipe where it goes through to the attic. Not only was it a gap for heat to pass through, it was also an escape for bats to leave the attic and enter my home. They can no longer enter. :) Thanks for the great product!!!

Does what is says on the box

Good quality

I have a wood burning fireplace that has two baffle boards on top of the firebox. One of the board was cracked and is quite expensive to replace. So I thought that instead of replacing the board, why not just add high temperature insulation on top to kind of seal off the crack. This insulation is exactly what I needed. It's easy to cut and after installing it on top of the existing baffle board, the fire seems to be burning hotter and cleaner, burning away all the smoke and giving out more heat. Overall, a great solution for my cracked baffle board.

Comes as advertised. Insulates against heat. Easy to use

Acheter pour protéger la proximité avec la cheminée! Efficace, mais ouf ça pique haha.
