7 Best Pizza Oven Insulation Materials (November 2026)
The best pizza oven insulation materials include the Cedolio 24" x12"x1" for a small repair area, the CeraTex 3180 Blanket with Aluminum Foil Facing for a moisture barrier, and the Lyrufexon Ceramic Fiber Insulation Blanket for a compact 1-inch layer.
On this page (4 sections)
The best pizza oven insulation for most constructed ovens is a ceramic fiber blanket that matches the oven plan's required thickness and coverage. The top pick here is a compact 1-inch sheet for small areas; for broader coverage, compare the longer blankets and measure your shell before buying.
Pizza oven insulation sits between the hot oven structure and its outer finish, helping reduce heat loss. The right material depends on where the insulation goes, how much surface it must cover and what the oven design specifies.
For a full build, check the design before choosing between a blanket and an insulation board. This roundup focuses on flexible ceramic fiber blankets, since those are the products available for comparison.

Cedolio 24" x12"x1": Best for a small repair area
- 24 x 12 x 1 in
- 2 sq ft coverage
- Rated to 2400°F
- Flexible and easy to cut
A compact 1-inch blanket for a small oven section or patch where a larger roll would leave more offcuts.
Pros
- 1-inch thickness
- Flexible and easy to cut
- Rated to 2400°F
Cons
- Only 2 sq ft coverage
Cedolio's 24 x 12 x 1 in sheet covers 2 sq ft, making it a sensible choice for a small area rather than an entire large dome. The 1-inch thickness suits plans that call for that layer depth, and the sheet can be cut with a sharp knife or blade.
Cedolio gives the blanket a 2400°F rating and describes it as flexible and tear resistant. Its stated uses include pizza ovens, along with stoves, fireplaces, kilns and forges.
The compact dimensions make it easier to plan a patch or small section without handling a long roll. Measure the area first and account for the cuts your oven shape requires.
Wear gloves and a mask when handling this blanket, as Cedolio recommends. That matters when trimming or moving the material during installation.
Choose this one when you need a 1-inch blanket for a small section and 2 sq ft is enough. For a larger shell, compare the coverage of the 60-inch options below.
CeraTex 3180 Blanket with Aluminum Foil Facing: Best for a moisture barrier
- 24 x 60 x 0.5 in
- 10 sq ft coverage
- Rated to 2300°F
- Aluminum foil facing
The foil facing provides a moisture barrier and radiant heat reflection, but its adhesive may smoke and smell if placed too close to the hot side.
Pros
- 10 sq ft coverage
- Foil facing adds a moisture barrier
- Flexible blanket
Cons
- Foil adhesive may smoke near the hot side
- Thinner than the 1-inch options
CeraTex offers 10 sq ft of coverage in a 24 x 60 in sheet, with a thinner 0.5-inch profile. Its aluminum foil facing is described as providing extra strength, a moisture barrier and radiant heat reflection.
CeraTex rates the blanket to 2300°F and describes it as lightweight and flexible. Its listed uses include pizza ovens, kilns, stoves, furnaces and foundries.
The foil facing needs careful placement. CeraTex warns that the lamination adhesive may burn and generate smoke and odor if the foil sits too close to the hot side.
Check the oven design to see whether a half-inch layer and foil facing suit the intended location. Choose it when you need broader coverage and can keep the foil away from the hottest surface.
Lyrufexon Ceramic Fiber Insulation Blanket: Best for a compact 1-inch layer
- 24 x 15.7 x 1 in
- 2.62 sq ft coverage
- Rated to 2600°F
- Scissors can cut it to shape
A small 1-inch blanket with a stated 2600°F rating, suited to a limited area that needs trimming.
Pros
- 1-inch thickness
- Rated to 2600°F
- Can be cut with scissors
Cons
- Limited coverage for a full oven shell
This Lyrufexon blanket measures 24 x 15.7 x 1 in and covers 2.62 sq ft. That gives it slightly more area than Cedolio's sheet while keeping a compact footprint.
Lyrufexon gives it a 2600°F constant-temperature rating and says scissors can cut it to the needed size and shape. The stated applications include pizza ovens, fireplaces, furnaces, boilers and forges.
The limited coverage makes it more suitable for a small build or a specific section than a whole large dome. Compare the measured shell area with the blanket dimensions before you settle on a quantity.
Lyrufexon recommends gloves and a mask when using the material. Follow that advice while trimming and fitting it.
Pick this option when a compact 1-inch sheet with a stated 2600°F rating fits your design. Choose the longer version below if you need more area from the same brand.
Lyrufexon Ceramic Fiber Insulation Blanket: Best for broader coverage
- 60 x 24 x 1 in
- 9.9 sq ft coverage
- Rated to 2600°F
- Scissors can cut it to shape
The long 1-inch blanket covers more area than the compact options and can be trimmed to fit an oven shell.
Pros
- 9.9 sq ft coverage
- 1-inch thickness
- Rated to 2600°F
Cons
- Check the full oven surface area before ordering
The longer Lyrufexon sheet measures 60 x 24 x 1 in and covers 9.9 sq ft. It keeps the 1-inch thickness of the compact Lyrufexon blanket while providing substantially more material to trim around a larger shell.
Lyrufexon gives this blanket a 2600°F constant-temperature rating and says scissors can cut it to shape. Its stated applications include pizza ovens and other heating appliances.
The bigger sheet may reduce the number of separate pieces needed, depending on the oven's shape and the design. Plan the cuts first, since a curved surface can require more material than a simple flat-area estimate.
Wear gloves and a mask as Lyrufexon recommends. Choose this sheet when its nearly 10 sq ft coverage is a closer match for your build.
Deouss Ceramic Fiber Insulation Blanket: Best for a medium-size section
- 24 x 32 x 1 in
- Rated to 2400°F
- Can be cut with a sharp blade
- Mechanical fastening or high-temperature adhesive
A 1-inch blanket in a middle-size sheet, with fastening options described for installation.
Pros
- 1-inch thickness
- Can be cut to shape
- Mechanical fastening or high-temperature adhesive
Cons
- Coverage is less than the long blanket options
Deouss provides a 24 x 32 x 1 in blanket, with 768 sq in of coverage. That middle-size sheet can suit a section larger than the compact 2 sq ft options but smaller than a long roll.
The blanket is rated to 2400°F and can be cut with a sharp knife or blade. Deouss describes mechanical fastening or high-temperature adhesive as installation options.
Check that a fastening method and adhesive are compatible with your oven design and the surface where you plan to install the blanket. The stated methods don't replace the builder's instructions for the completed oven assembly.
Deouss lists pizza ovens among the intended applications. Choose this one when the 24 x 32 in sheet dimensions match the area you need to cover.
Amylove 2 Pcs Ceramic Fiber Insulation Blanket: Best for two large sections
- Two pieces, each 60 x 24 in
- 0.98-inch thickness
- Rated to about 2600°F
- Can be cut with scissors
Two large pieces can suit a build with separate areas to cover, and the blanket can be cut to size.
Pros
- Two pieces included
- Large sheet dimensions
- Can be cut with scissors
Cons
- Thickness is just under 1 in
Amylove includes 2 pieces measuring 60 x 24 in each, with a stated thickness of 0.98 in. The two sheets can serve separate sections of a build, or provide extra material for planned cuts.
The blankets are made of aluminum silicate and described as suitable for high-temperature insulation. Amylove gives them an approximate 2600°F temperature rating and says scissors can cut them to size.
The product information describes uses in kilns, chimneys, forging work and other high-risk fire areas. It does not name pizza ovens in the bullets, so check that the material and its installation suit your particular oven plan.
Amylove recommends gloves and masks when cutting. Choose this pack when two large sheets fit the way you plan to cover the oven.
SIMOND STORE Ceramic Fiber Insulation Blanket: Best for a thinner layer
- 24 x 36 x 0.5 in
- Rated to 2400°F
- 8 lb/ft³ density
- Can be cut to shape
A half-inch blanket for a design that calls for a thinner layer or for pairing with other suitable insulation.
Pros
- Large sheet dimensions
- 0.5-inch thickness
- Can be cut to shape
Cons
- Thinner than the 1-inch options
SIMOND STORE's blanket measures 24 x 36 x 0.5 in, making it a thinner option than the 1-inch picks. The stated density is 8 lb/ft³, and the material can be cut to size or shape.
Its temperature rating is 2400°F. The described uses include oven insulation, furnaces, kilns, forges and other heating equipment, so confirm it suits your oven's location and construction plan.
At half an inch thick, it may fit a design with less space for insulation or one that calls for a thinner layer. Do not assume that stacking layers is suitable without checking the build guidance.
Pick this sheet when your design specifies a half-inch blanket and its dimensions cover the section you need. A 1-inch option is a closer fit when the plan calls for more thickness.
How should you choose insulation for a constructed pizza oven?
Choose pizza oven insulation by matching its material, thickness and coverage to the oven design. A temperature rating is one part of the decision, not a substitute for placement instructions.
Start by measuring the oven surface that needs insulation. Compare that area with the stated coverage, then account for curves, overlaps and trimming based on the design.
What size pizza oven insulation blanket should you buy?
Buy enough material to cover the planned insulated area, with allowance for fitting and cuts. The compact sheets here cover about 2 to 2.62 sq ft, while the larger options cover roughly 9.9 to 10 sq ft or come as two wide sheets.
A dome can take more blanket than its base diameter suggests because the insulation wraps around a curved surface. Sketch the sections and cuts before choosing how many sheets to buy.
Should you choose a 0.5-inch or 1-inch blanket?
Choose the thickness specified by your oven plan. The products here include half-inch blankets and options close to 1 inch, but a thicker sheet is not automatically right for every design.
A thinner layer may fit where space is limited, while a 1-inch blanket suits plans that call for that depth. Confirm whether the finished oven design uses one layer, multiple layers or a different insulation material.
Are ceramic fiber blankets safe to handle?
Follow each product's handling guidance and the oven builder's installation instructions. Cedolio, Lyrufexon and Amylove recommend wearing gloves and a mask when handling or cutting their blankets.
Cut only in a suitable work area and avoid disturbing the fibers after installation. If you're unsure about safe handling or the finished assembly, consult the oven manufacturer or a qualified builder.
How does insulation affect pizza oven heat?
Insulation helps reduce heat escaping through the oven shell, which supports heat retention. It works alongside the oven's floor, dome, fuel and firing method, so it does not set the cooking temperature by itself.
Read what a pizza oven is and how it works for the role of its main parts. Your oven's heat-up process also depends on what you need to preheat a pizza oven.
Will insulation determine the right pizza oven temperature?
No, insulation alone doesn't determine the cooking temperature. The oven design, fire, fuel and preheating all affect the conditions at the floor and dome.
For Neapolitan-style pizza, use the guidance in what oven temperature you need for Neapolitan pizza. Follow the oven maker's instructions for the safe limits of your own build.
Does wood choice change how the oven heats?
Yes, fuel affects how you build and maintain a fire, while insulation affects how much heat the oven shell retains. Choose wood suited to your oven and cooking plan, then learn how to choose wood for a pizza oven.
Use the oven's own operating guidance when lighting or tending a fire. The safest way to preheat a pizza oven covers precautions for that step.
Which pizza oven insulation should you pick?
Choose Cedolio for a compact 1-inch sheet, the longer Lyrufexon blanket for broader 1-inch coverage, or CeraTex when its foil facing and thinner profile match your oven plan. Before choosing any pizza oven insulation, measure the shell and confirm the required material, thickness and placement with the build instructions.

Frequently asked questions
What insulation is best for a pizza oven?
A ceramic fiber blanket is a practical choice for insulating a constructed pizza oven because it is flexible and can be cut to fit a curved shell. Choose a thickness and coverage that suit your oven design, and confirm the material is rated for the temperatures and placement involved.
Follow the oven builder's installation guidance.
How thick should pizza oven insulation be?
Thickness depends on the oven plan and the space available around the dome. The choices here range from 0.5 to 1 inch, but those dimensions alone don't determine how much insulation a complete build needs.
Measure the area and follow the design's specified insulation layers.
Can ceramic fiber blanket touch the oven?
Use ceramic fiber blanket only where your oven design allows it, and check the temperature rating and installation instructions. A foil-faced option needs extra care because its adhesive may burn, smoke and smell if the foil sits too close to the hot side.
Wear gloves and a mask when cutting or handling blankets that recommend protective gear.
How do I estimate how much insulation to buy?
Measure the surface area you plan to cover, then compare it with each blanket's stated dimensions and coverage. Add room for overlaps and cuts according to your oven design, since a curved shell can use more material than its flat measurements suggest.
Plan placement before trimming.
Does insulation make a pizza oven heat faster?
Insulation helps limit heat loss through the oven shell, which can help the oven retain heat. The time it takes to preheat also depends on the oven's construction, fuel, fire and target temperature.
