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.

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.

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.
