Ceramic fiber board?

Found this stuff locally. Isaform 2300 MD. I’m trying to determine if it’s dense is enough to support the weight of the oven. Nominal density 18-22 lb/ft3. Unable to convert that to something I understand. Link below. Thanks

Temp rating looks good, materials, AlSI is a common refractory material. You need to find out two things. Compressive strength, should be at least 75 psi at 5% and K values at pizza oven temps.
