Gypsum-Lime & Alabastine Insulation: Are They Asbestos-Free?

No, neither gypsum-lime nor alabastine insulation contains asbestos. Gypsum-lime insulation is a mixture of gypsum plaster and lime, while alabastine insulation is made of calcium sulfate. Asbestos is a naturally occurring fibrous material that was commonly used in building materials until the 1970s when it was found to be a health hazard.
