20mm T&G MgO Structural Subfloor Board
This 20 mm sanded magnesium oxysulfate board is configured with tongue-and-groove or shiplap edge options for single-layer structural subfloor applications. It is the supporting panel beneath the final floor finish and is not a finished flooring product.
The T&G configuration does not replace structural design. Span, design load, support spacing, edge support, fixing pattern and the final floor build-up must be confirmed before production.
