MOISS TM is a calcium silicate board, produced by forming and curing a slurry of siliceous, calcareous, and fibrous materials. As a structural sheathing material, it provides several key benefits, including fire resistance, earthquake resistance, and excellent humidity control. Its components are primarily derived from natural materials and are free from harmful substances. It is mainly used for residential applications. MOISS TM products are available in thicknesses ranging from 9.5mm to 12.5mm, with the 9.5mm thickness having the highest annual production volume. Environmental impact data in this document is based on the 9.5mm thickness. Data for the 12.5mm thickness, including A1-A3 environmental impact assessments, has been evaluated separately. The Global Warming Potential (GWP) data is provided in the appendix.
