Sanded Magnesium Oxide Underlayment Board
This configurable magnesium oxysulfate board has a sanded surface for underlayment and selected subfloor build-ups. It is supplied as a supporting board layer beneath the chosen finished floor system and is not a finished flooring product.
Underlayment and structural subfloor are different duties. State whether the board must carry structural loads so the appropriate thickness, support spacing, edge detail and fixing method can be reviewed.
