Sheathing boards are used in roof, wall, and floor assemblies. They provide a nailing base onto which other building materials can be fastened.
Structural exterior sheathing panels protect structures from outside elements and offer resistance to twisting and bending. They’re used to tie framing studs together—also referred to as ‘wall bracing.’
In building construction, structural sheathing plays a significant role when it comes to helping structures withstand wind loads, transferring them to the building structure and backup wall framings.
Common sheathing types include OSB, plywood, glass-faced gypsum panels, and hybrid products like MgO sheathing boards—all of which integrate both insulation and weather barriers.
When opting for structural sheathing, here are some factors you need to consider:
Strength should be the top priority when selecting sheathing. Sheathing panels require good racking strength and load capacity. This is where sheathing boards that are made of MgO technology come in!
They use four layers of high tensile fiberglass meshed to offer more than 38Mpa of impact strength, and bending strength of over 22Mpa.
This ensures durable construction compared to drywall. Plus, MgO sheathing boards prevent abrasions and scruff.
Efficient Fastening Method
The structural sheathing board you opt for should be easy to install, shape, drill, cut, and fix—resulting in a clean square cut for higher-quality installations. Moreover, it should be maintenance-friendly.
The MagMatrix MgO boards can be cut accurately—with precision and depth adjustment—using electric saws, facilitating accurate and fast work.
Compared to drywall screws—which often snap off—MgO boards are fastened with high-quality screws, siding nails, and framing nails.
Water and Weather Resistance
Structural sheathing should ideally be weather-resistant and virtually impervious to water.
Since MagMatrix MgO boards are insoluble in water, they prevent the swelling of the board after long-term exposure to moisture. Thus, they maintain outstanding dimensional stability, even during humid and damp conditions.
What’s more, sheathing boards that are made of MgO can be installed early on in the construction process—either before the building is weather-tight or during semi-exposed applications.
While not a lot of sheathing board options offer fire-protection, the MagSF sheathing board model is particularly implemented as a fire-resistant solution. Not only is it breathable, but it also provides outstanding fire-resistance properties that prevent fires from engulfing entire buildings quickly.
MagMatrix MagSF non-combustible sheathing boards are an exceptional green alternative when it comes to structural sheathing options.
