class a thermal insulation materials include: inorganic thermal insulation mortar (with two components and one component), expanded vitrified bead thermal insulation mortar, inorganic high-efficiency composite thermal insulation mortar, SF hydrophobic expanded bead thermal insulation mortar, FTC phase change thermal insulation materials, etc. Thermal insulation mortar with expanded vitrified beads and inorganic high-efficiency composite thermal insulation mortar are generally used for building interior wall insulation, while SF hydrophobic thermal insulation mortar with expanded beads and FTC phase change thermal insulation materials can be used for building exterior wall, roof and interior wall insulation engineering.
