Technical articles, market trends, and buying guides for calcium silicate insulation. Written by engineers at a 34-year insulation manufacturer.
Everything engineers need to know before specifying calcium silicate: xonotlite crystal chemistry, how autoclave curing at 190–220°C produces the critical crystal phase, ASTM C533 Type I vs Type II classification, thermal conductivity formula, density-strength trade-offs, and a practical ordering checklist. The definitive reference from a manufacturer with 34 years in the material.
