    Definitely not. Any flame held directly against it would char it and compromise the structure. It's sort of like how wool will burn but it won't start a self sustaining combustion.

    Will this work to insulate a pizza oven floor, and if so can I get just one?
    1 Answer
    While we do not offer single panels and only offer the set of four, this product would likely not be the best option as it is not food safe and shouldn't be used in the construction of a pizza oven, which would especially be the case if this is actually an outdoor pizza oven as Micore should also not be exposed to moisture. We do offer this product which is made specifically for insulating manufactured outdoor pizza oven kits we also offer.  If you actually looking for material to use for the oven floor itself and not just insulation, firebrick is normally used for this application.

    from Detroit asked:
    December 3, 2019
    Would this be good to use with a wall-mountable ethanol fireplace? Manufacturing states the wall should be a fireproof wall.


    1 Answer
    That is more of an insulating material. A good non-combustible wall product would be a cement board or Hardie Backer. Although Micore 300 is used as part of building a non-combustible surface, it would not work well as a finish or top layer of a wall.

    I have Micore 300 boards and plan to cover them with metal for protection of the floor under the hanging fireplace. The two layers of boards will provide more than the required R value. Is there any specific requirement for the type or gauge of metal as well?

    1 Answer
    No, if the R value is satisfied, there is no requirement on the gauge of metal that can be used.

    Can I mortar ceramic tile directly onto this SBI Micore-300 mineral fiber board or does it need a layer of cement board first?

    A cement backer board should be used first. The Micore product is not a high density material and compressibility is high enough that concentrated pressure from a stove leg or other point of contact could cause a shift or crack in the tile veneer.

    1 Answer
    Granite can "float" directly upon the Micore product. However, if you are planning to adhere the granite permanently, a layer of cement backer board should be screwed to the Micore first, as adhesive does not hold well to the mineral construction of the Micore product.

    If the installation calls for a 1/2 inch Micore board and 24 gauge steel sheet for floor protection, which goes on top and which is the bottom next to the floor? How should it be fastened down?
    1 Answer
    The 1/2 Micore board should be used as the substrate with the steel sheet placed over the top of the Micore for additional protection and finishing. If the Micore is upon a combustible surface, wood screws should be used every 6 to 8 inches to secure the Micore to the floor. The 24 gauge steel can then be secured to the Micore using construction adhesive.

    Sauna Heat Shield Application
    After contemplating how to make an existing small, Cedar log sauna building as safe as possible for a wood burning stove (Kuuma), I was advised by a fireplace company to look into Micor. I've only just started using the outdoor, rustic sauna but so far, so good. It seems to be doing the job. I feel it's as safe as I could get the heat shields (Dura Rock on the wall, spacers of 2 inches and then Micor) it so it's worth the extra cost.

    Impossible to find Except here.
    My wife and I purchased a new Medota gas fireplace and we're having a granite hearth installed which required a half inch fiberboard with an R-factor that was at least 1 or higher. I researched and found that Micore Mineral Fiberboard 300 was exactly what I needed but no one on Long Island, New York sold it. I found a hardware store in Ohio that would ship me a pallet with 75 pieces and I only needed one. Then I found the e-fireplace store that shipped me a package of 4 with no shipping charge for $125. The package arrived in 3 days and our hearth was installed that same day. We are now enjoying our new fireplace thanks E-Fireplace Store.

    Glad I Found This Product!
    I am so glad I found this product. My wood burning stove requires a hearth with an R-value of 1.2. I couldn't find any way to make that happen until I stumbled across this mineral board. I put this down and then applied a 1/2" thick cement board on top of it and then set porcelain tile using thin set mortar and grout. I ended up with a beautiful hearth that exceeds requirements.
    ProsLightweight Easy to work with the product High R-value
    ConsEasily damaged if dropped on corners. My box was apparently dropped on a corner during transit. I was able to cut off the damaged areas and still had plenty to complete my project. It would be nice if the packaging could be strengthened at the corners to prevent damage during shipment.

    amazing product
    I purchased this for our fireplace facing the area above a gas fireplace that prevents heat from transfer and combustion of regular drywall materials. The fireplace was installed by someone else and was too close to tv and also too large of a unit. We had hardi board but that was heating and retaining heat. We used micore 300 and finished with wire mesh and durabond spackle, came out great heats about 40-50% less than cement board. One note if not going to install cement board on face of micore 300, and going to use as finished wall surface prime the board first.
    Original fireplace came with 5" of "non combustible facing" but was unable to order more this actaully worked out for me getting almost 18" of micore 300 instead of 5" that came with.

    Proslight weight withstands high heat low thermal transfer
    Consonly con and mostly because i am using as a finished wall surface is needs to be primed prior to spackle ( not exactly a con just using in ways different than intended)

    SBI Micore-300
    I am using this "stove board" as a heat berrier between the roof of my porch and a patiio heater. Not enough space to feel safe without shieldThe patio heater puts out 36000 btu on high. I had only apx. 10" or so between the roof and top of heater.So, I ordered this Fiber Board and put it between two pieces of sheet metal.Added a few nuts and bolts to keep it in place and have had good results. This heat shield fits above the heater apx.6"-8 " and between the rafters. I can hold my hand above the shield with heater on high. I have heat resistant paint on the sheet metal and the paint did not peel or burn off. I did not cut the board. Used 24x48 piece since my rafters were 24" on center. So far so good. The product works.
    ProsSo far pruduct performs as claimed. Works well for my application. Reduces space needed between heater/stove and in my case roof boards.
    ConsWill soak up moisture. For my outdoor use wish it was more "outdoor" usefull. I painted over it to hopefully seal it better.Yes, using hi-temp paint.

    Micore for a woodburner hearth pad
    I have not installed this item yet but am so happy to have found it. I asked at a woodburning stove sales shop what insulating board to use for a hearth pad. They recommended Micore Fiber Board and since I had heard of it I welcomed the endorsement as I was already leaning that way. However, they said it was readily available at home improvement stores but I found that is not the case. Thanks to this seller for carrying it!

    The only insulating board I have found for making a stove board.
    I have had no success in finding suitable stove boards at a reasonable price, so I decided to make my own. I previously purchased Micore 300 to make a stove board for the wood stove at my hunting cabin. I had a local sheet metal shop make me a 44" square pan, 1" deep. Painted it black and turned it upside down on 2 layers of Micore, and I had a reasonably priced stove board with an R factor of 2.06. I used 14 gauge metal, which spread the weight out enough for the Micore to be able to support my stove (350#). I am putting another stove in an addition at my house, so I am doing another homemade stove board. I have no doubt it will work out just as good as my first one.
    ProsReasonable price, quick shipping, sturdy product.
    ConsA little damage to the edges in shipping. Not really a problem for me because I had to trim the pieces anyway.

    Micore 300 was not the easiest stuff to find, and it is pricey, but you get what you pay for! It allows you to make a fireplace hearth that is a lot thinner, rather than using thicker materials, to obtain the ''R'' required.This seller is one of the few places I found that carry Micore, and their shipping was super fast!! I sandwiched the micore between two 1/2'' sheets of Durock next generation cement board, and then finished with multi color slate tile cemented on top.Looks fantastic, and is more protective than the 1.2 R factor that my stove required..
    Prosgreat insulator
    Conskind of pricey

    A product that is easy to install..and works
    I had a problem with my ceiling for a number of years now and went to a store that sells stoves and asked him about my problem which was paint flaking off my ceiling. I have repaired it many times but to no avail. The man in the store stated that my smoke pipe is too close to your ceiling and then i asked him what he would put on the ceiling..he said Micore-300 Mineral Fiber Board.! and so i ordered it and installed it over my ceiling with screws going into the ceiling joists...
    ProsI was told that this item is put into the backs of stoves

    Good price for hard to find Item
    I was installing a slate pad for under a wood stove and wanted to protect the original hard wood floors, century and a half old house. In my area this product is not carried in the hardware stores. They could order it for me but I would have to wait for the next USG shipment of drywall, maybe weeks. Both price with shipping and timing were better than any local store offered me. Very happy , pad and stove installed.
    ProsThe product is a heat barrier, it preforms as described. The time to delivery and price were what was exceptional.
    ConsNo cons.

    Great product, Great Price
    I was already aware of the benefits of Micore for building my hearth but I was surprised to find it here for less than Amazon and the shipping was fast.
    ProsGood product
    ConsYou can't buy one sheet.

    High R value, light weight and easy to use.
    We installed a wood burning stove over hardwood floors in a house with a basement. Because of the weight of the stove we didn't want to add a lot more weight in the floor pad. It needed an R value of 1.5. By using the Micore 300 in place of many layers of durarock we achieved the R value we wanted without it weighing a ton. We used 1/4 " plywood and the Micore was sandwiched between the durarock. On top is ceramic floor tile. The Micore was easy to cut and light weight. I only gave it 4 stars because I thought it was pricy.

    Exactly What I Needed
    This product is fairly hard to find, but FS had it shipped to my door very quickly. My only caveat is that it comes in a large quantity. If it came in a package with half the coverage I would have given it 5 stars.

    Micore-300 Mineral Fiber Board completed our Wood Stove
    The product was easy to use and just what wee needed to complete our hearth for our wood stove. We had to abide by the codes since we put it into our manufactured home. I would recommend this product to others. The price was also in our budget.

    A Complete Minimum Clearance Solution
    I bought this product so I could comply with my wife's request that our new wood stove be placed closely as possible against the wall and without a raised hearth. This product solved all of our clearance issues in as much as a one half inch thick sheet has the heat transference protection of nearly six inches of concrete!
    ProsGreat product with excellent heat transfer retardancy values.
    ConsThere was nothing that I disliked about the product itself. I was simply surprised that it was so difficult to locate. In that regard, I am especially grateful to this store for including it in its inventory of wonderful products.
