  • Please check if my insulating materials are correct?

    Hi everyone,

    I'm about to order all of the insulating material for my pizza oven. For the floor, I plan on doing 2" Foamglas and then 2" CalSil. For the dome insulation I will do 3" of ceramic fiber blanket. Can you please double check that I am ordering the correct material? There's so many options and I want to make sure the specs are correct.

    Foamglas
    Compressive Strength : 60 psi
    Density : 7.18 pcf
    Flame Spread Index : 0
    Flexural Strength : 41 psi
    Insulation Thickness : 2 in
    Item Name : Foamglas Block
    Length : 24 in
    Material : Foamglass
    Smoke Developed Index : 0
    Sub Brand : ONE
    Temperature Rating : 121 to 800 deg F
    Thermal Conductivity : 0.14 to 0.54 Btu-in/hr-sq-ft-deg F
    Water Vapor Sorption : <0.2 %
    Width : 18 in

    Thermo-12 CaSi Boards
    Compressive Strength : >100 psi
    Construction : Flat
    Density : >14 pcf
    Flame Spread Index : 0
    Flexural Strength : >50 psi
    Insulation Thickness : 2 in
    Item Name : Calcium Silicate Block
    Length : 36 in
    Material : Calcium Silicate
    Smoke Developed Index : 0
    Special Features : Non-Water Resistant
    Sub Brand : Thermo-12 Gold
    Temperature Rating : 1200 deg F
    Thermal Conductivity : 0.344 to 0.647 Btu-in/hr-sq-ft-deg F
    Width : 18 in


    Blanket
    Color : White
    Density : 8 pcf
    Insulation Thickness : 1 in
    Item Name : Ceramic Fiber Blanket
    Length : 25 ft
    Material : Ceramic Fiber
    Series/Model : Durablanket S
    Specific Heat : 0.27 Btu/lb-F
    Sub Brand : Fiberfrax
    Temperature Rating : 2300 deg F
    Tensile Strength : 7 psi
    Width : 24 in


    For those that ordered through Distribution International, how was your experience? Seems like they only work with contractors/businesses and not your typical DIY guy.. but I could be wrong.

    Anyways, thanks in advance for your help!

    I deleted the direct commercial links (not allowed) but that said, DI is a good source. I purchased CaSi and FoamGlas from DI and the blanket is the right product.

      +1 on Russell's advice. I too got my insulation from DI. Just make sure that you are ordering the solid Thermo-12 Gold board. The boards on the left in the pic are scored to fit large piping and round vessels. Someone mistakenly ordered the scored for their oven. You want the solid board. It also comes in water resistant and non-water resistant. I believe that the water resistant may have just a little less insulating factor. I have no experience with it. Regardless, you will want to keep you oven dry.

        Whoops. Sorry about that - I did not realize that was against community guidelines. I am aware that posting links to promote a product is not allowed, however, that was not my intention at all and was just linking for help.

        Anyways, thanks for your help. It sounds like I have the right blanket material and CaSi board picked out. The only thing I still need help with is the foamglas. Since I cannot post links I will copy over the specs. Please let me know if this is correct?

        FoamGlas:

        Compressive Strength : 60 psi
        Density : 7.18 pcf
        Flame Spread Index : 0
        Flexural Strength : 41 psi
        Insulation Thickness : 2 in
        Item Name : Foamglas Block
        Length : 24 in
        Material : Foamglass
        Smoke Developed Index : 0
        Sub Brand : ONE
        Temperature Rating : 121 to 800 deg F
        Thermal Conductivity : 0.14 to 0.54 Btu-in/hr-sq-ft-deg F
        Water Vapor Sorption : <0.2 %
        Width : 18 in

            May I ask why you arent just doing 4" Casi board instead of doing 2" casi board and 2" foam glass?

              It's because he has chosen the non-water resistant CaSi board, so the FoamGlas will provide a water resistant layer (+insulation) between his concrete hearth and the "water loving" version of CaSi board. The combination of CaSi+FoamGlas board materials will provide excellent heat retention and also help keep his oven floor insulation dry. If he chose to use the Thermo-12 Gold board with the water resistant option, he wouldn't gain anything by using the FoamGlas.

                Exactly. Sable, do you have any insight on the Foamglas I am going to order? Does this look like the right stuff?
