A White T&G (Tongue & Groove) Subflooring MgO (Magnesium Oxide) Board represents a heavy-duty, structural-grade flooring substrate designed to replace traditional plywood, OSB, and fiber cement underlayments.
By combining the structural interlock of a machined Tongue & Groove profile with the fireproof, water-resistant properties of MgO chemistry, these boards create an ultra-flat, non-combustible, and acoustically quiet subfloor matrix.
| Property | Standard Metric/Specification | Engineering Advantage |
| Typical Thickness | 16mm, 18mm, or 20mm | Matches or replaces standard 3/4"plywood/OSB subfloors. |
| Density Range | 1050 to 1200 kg/m3 | Structural grade; delivers solid underfoot feel with zero bounce. |
| Fire Performance | Class A1 / Class 0 (Non-combustible) | Acts as an integrated fire barrier between floor assemblies. |
| Flexural Strength | High Modulus of Rupture (MOR) | Easily supports ceramic tile, stone, or heavy screeds without cracking. |
