Is It Possible To Use Magnum Board For External Sheating?

Magnesium board products, such as wall sheathing, trim, fascia, and siding, have significantly changed the landscape of exterior sheathing due to their numerous advantages over traditional materials. In 2010, magnesium oxide (MgO) boards became popular in Denmark for use inside ventilated spaces, replacing drywall in public housing and private homes and as an exterior sheathing in commercial buildings. However, widespread failures occurred about five years later.

Wall sheathing provides varying levels of thermal properties and is important for HVAC air retention. The top five exterior sheathing materials include oriented, wood-based, gypsum, and MEGCRETe boards. These boards are reasonable in cost, provide a surface for material application, and help shield a structure from rain, snow, and wind.

Magnum and MEGCRETe boards can be used as structural sheathing applied to interior and exterior wood-framed walls to resist uniform transverse loads and racking shear loads. They are NZ appraised for interior use including wet areas and exterior use. Magnum Board® is used as a sustainable, healthy, breathable, and safe alternative to internal wall lining, tile backer, floor underlay, and rigid air barrier (RAB).

Magnum Board is available in both fire rated and non-fire rated options, and it is technologically advanced, high-quality Magnesium Oxide Boards. Recent activities have focused on comparing the properties of MgO boards based on chlorides or sulphates, particularly for use in potentially damp or wet exterior cladding environments.

MEGCRETe sheathing is also ICC-ES certified for use in the United States and is FIRE, MOLD, and MILDEW certified.

Is cement board ok to use outside?

PermaBASE cement board products are a cost-effective and easy-to-install solution for exterior walls, offering enhanced durability and moisture resistance. These boards help prevent mold, mildew, and other water damage, making them an ideal choice for building projects. PermaBASE Building Products provides product information and installation instructions for all exterior cement board applications, highlighting the benefits of using PermaBASE Cement Board for efficient and cost-effective exterior wall systems.

What are the disadvantages of magnesium oxide board?

A study conducted by the University of the Sunshine Coast has revealed that magnesium oxide (MgO) wallboards have the potential to cause damage to surrounding structures, including dampness, cracking, and accelerated corrosion of metal fixtures. The zinc coating of the steel profile is subject to corrosion as a result of direct contact with saline water that has leaked from the adjacent MgO board.

Is magnesium oxide board waterproof?

MgO boards are structurally stable and resistant to moisture and water, although they are not waterproof. These materials do not undergo any dimensional changes, such as swelling or warping, nor do they delaminate. They can therefore be used to protect against moisture in basement flooring. Prolonged exposure to water can result in hypothermal expansion. It is possible for boards located in coastal areas to sustain damage due to the effects of saltwater exposure. However, the implementation of an additional external finishing layer can effectively mitigate this risk.

Is magnesium board waterproof?

MgO boards are structurally stable and resistant to moisture and water, although they are not waterproof. These materials do not undergo any dimensional changes, such as swelling, warping, or delamination. Furthermore, they can serve as a protective barrier against moisture accumulation in basement flooring applications. Prolonged exposure to water can result in hypothermal expansion. It is possible for boards located in coastal areas to sustain damage from saltwater exposure. However, the use of an additional external finishing layer can mitigate this risk.

Which side of Magnum board goes up?

A common inquiry among potential users of Magnum Board Flooring Underlay is whether the underlay should be installed with the surface facing up or down. The recommendation is to install it with the surface facing up, as this does not significantly impact the underlay’s performance.

How long will cement board last outside?

Fiber cement siding is a durable and cost-effective option for homeowners, with an average lifespan of around 50 years. It comes in various colors and styles and doesn’t require significant maintenance. The cost of installation depends on the type of siding and the value of professional installation. Fiber cement siding can enhance curb appeal and provide a return on investment at a reasonable cost. Its composition of cement, wood fiber, and sand makes it a good candidate for recycling, as disposing of materials at a landfill poses no environmental hazards.

Is A fire Board waterproof?

Marmox Fireboard is a durable, water-resistant material that offers long-term durability and protection against moisture. Its waterproof properties protect the underlying structure from potential water damage, ensuring it remains intact even in damp conditions. Fireboard also helps prevent mold growth by repelling water, maintaining a healthier indoor space. This makes it suitable for use in bathrooms, kitchens, and other areas where moisture resistance is essential. Marmox Fireboard’s exceptional waterproof properties surpass traditional building materials, ensuring it remains intact even in damp conditions.

Can cement board be used as exterior sheathing?

Structural exterior wall sheathing is crucial for a home or commercial building’s integrity and rigidity. It provides a surface for materials like siding and shields the structure from various weather conditions. Common options include wood-based, gypsum, glass mat, cement board, and Barricade® Thermo-Brace®. Plywood sheathing is made from cross-laminated wood sheets, providing strength and stiffness. It is lighter and has good moisture resistance.

Oriented strand board (OSB) is a durable panel sheathing made from hundreds of thin wood strands hot pressed onto sheets. OSB panels are dense and solid, with no soft spots. OSB is often less expensive than plywood but has more volatile pricing. Waferboard sheathing is a manufactured product made by placing small pieces of wood scraps in a hydraulic press and gluing. Although less expensive, waferboard is weaker and less resistant to water.

What is the fire rating of Magnum board?

Magnum Board 60 Minute Fire-Rated Wall Board is a sustainable, environmentally friendly alternative to traditional wood fiber, plywood, gypsum, and cement-based substrates. It is manufactured without harmful chemicals and offers superior performance. New Zealand’s Health Based Building Materials Specialists offer an exclusive range of building materials, including hardwood and softwood timber, vapour permeable exterior and interior wall boards, breathable paints, and oil coatings.

Is a magnesium board breathable?

Magnum Board is a sustainable building material composed of high-quality magnesium oxide. It is characterized by breathability and the absence of harmful chemicals. The material’s ability to permit wall and floor systems to “breathe” contributes to ecological and sustainable development, rendering it an optimal solution for individuals afflicted with allergies.

What kind of board is fireproof?

FIBRODICE MS is a board made from reinforced magnesium silicate, offering high dimensional stability and thermal and acoustic insulation for fire protection applications. It is non-combustible and manufactured without asbestos. Applications include insulation for wood and metal fire-resistant doors, floors, ceilings, partitions, and protection of metal structures.
