    I was talking to one of our subcontractor installers the other day about a source on Micore 300. He said that he no longer uses it because of the density and fragility. He has been using this product for years, apparently its structural, and has a 1.2 r value per 1/2". Mabey someone can confirm that with the specs listed below. Have any of you used this product?




    MariniteTM I panels can be used in construction and refurbishment of ovens, dryers and other insulated housings for the retention of control or heat. It, also, can be used in areas of fire protection, fire training, and as lightweight insulation panels

    MariniteTM I combines structural strength with high thermal insulating values. It is incombustible, highly damage resistant, non-corroding, and extremely water resistant. Mariniteâ I panels also provide fire safety, uniform temperature control, and require minimal maintenance.

    I think you found the problem! :)
    Micore 300 is $30 for a 4x8 sheet.
    I've heard complaints before about the fragility of micore 300 but I don't really get it. Who cares if its almost as fragile as cardboard? It doesn't seem to compress much, I used it in my hearth pad and it worked out just fine, many others have as well.
