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 use this for high temperature patches and repairs on ceramic kilns. It holds up well, is easy to handle and can stand high ( 2300 F ) working temperatures with no changes.

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.

This stuff is amazing It works so good I was blown away. I have a torch lighter that will eat through an aluminum can in about 3 seconds. I hold the stuff up hit it with the torch for probably 15 or 20 seconds solid. It was glowing red. Took the torture away in 3 seconds later I touched it and there was no heat left. Amazing!!

easy to cut and fit. It really worked well for the back of my pellet stove would buy again

The seller delivered on time, and the product works as expected

I can't find a perfect fit liner kit for my old burner, but I found this to save my burner, easy to cut and custom fit

I used this ceramic fiber insulation to insulate the exhaust pipe on a diesel heater from a window and works for what I needed. Nothing around the exhaust pipe is remotely burnt or even heats up much where the insulation is protecting.Before cutting WEAR GLOVES at the minimum and even protective eyewear and a dust mask. Cutting the insulation mat creates a lot of ceramic dust and causes you to itch.

Easy to cut. And easy to work with.
