January 6, 2022
Can you please tell me how this micore is installed over the OSB for my fireplace hearth? Can you recommend what screws I need?  I plan to use slate tile for the hearth.  Maybe solid slate?  Will 1/4 durarock be sufficient as I read the micore is soft? Can the micore and durarock be screwed together at the same time without anything between them? I read that tile shouldnt go directly on the micore.Â
1 Answer
It is indeed not recommended for Tile to go directly over Micore as the product is not rigid. You can screw your Durock and Micore down at the same time using wood screws for the Micore, or the screws recommended by Durock, but long enough to accommodate both layers.

How do I adhere the Micore 300 to my (OSB) subfloor? Can I install tile directly on the Micore 300?
1 Answer
These Micore boards can simply be screwed down to the subfloor using wood screws. Tile should not be directly applied to Micore and a layer of cement board should used.

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.

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.

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

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.

Just what I needed for floor protection project
I needed a non-combustible board with a minimum insulation rating to build in a floor protection system for a wood-burning kitchen range. This board will be the bottom layer of the protection system followed by cement backer board and then ceramic tile. The top of the ceramic tile will be level with the surrounding kitchen floor for a better look and avoidance of any tripping hazards.
Nice size for handling, just the right thickness to provide required R-value, easy to work with.
A little more expensive than my original calculations, but then everything construction related has increased in price.

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.
Lightweight
Easy to work with the product
High R-value

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.
light weight
withstands high heat
low thermal transfer
only 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)

The product ended up being shipped from the manufacturer in Canada. This held up my hearth project for a while but all's well that ends well.

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.
So far pruduct performs as claimed. Works well for my application.
Reduces space needed between heater/stove and in my case roof boards.
Will 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.
Reasonable price, quick shipping, sturdy product.
A little damage to the edges in shipping. Not really a problem for me because I had to trim the pieces anyway.

micore300
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..
great insulator
kind 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...
I 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.
The product is a heat barrier, it preforms as described. The time to delivery and price were what was exceptional.
No cons.

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.

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!
Great product with excellent heat transfer retardancy values.
There 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.
