MGO boards are a highly versatile building
material used in a wide range of applications, both residential and commercial.
Their unique combination of fire resistance, moisture resistance, and strength
makes them an excellent alternative to traditional materials like drywall,
cement board, and plywood.
Here are the most common applications for
MGO boards:
1. Interior Wall and Ceiling Panels
This is one of the most popular uses for
MGO boards. They can be used as a direct replacement for gypsum drywall in
homes, offices, schools, and hospitals. Their benefits in this application
include:
- Fire-rated walls and ceilings: MGO boards are non-combustible and can be used to construct fire-rated
assemblies, which is crucial for building codes, especially in multi-story
or commercial buildings.
- Moisture-prone areas: Their
resistance to water makes them ideal for walls and ceilings in bathrooms,
kitchens, laundry rooms, and basements where moisture and potential for
mold growth are a concern.
- Durability: MGO boards are stronger
and more impact-resistant than drywall, making them suitable for
high-traffic areas like hallways, gymnasiums, and stairwells.
- Acoustic insulation: They can also
provide soundproofing, making them a good choice for shared walls in
apartments, hotels, and recording studios.
2. Exterior Sheathing and Siding
MGO boards are increasingly used as a
sheathing material on the exterior of buildings. When used as sheathing, they
provide a strong, weather-resistant, and fire-resistant layer underneath the
final siding or cladding.
- Weather Resistance: They do not
swell or rot when exposed to moisture, making them an excellent barrier
against rain and humidity.
- Fire-Rated Assemblies: MGO
sheathing contributes to the overall fire safety of the building envelope.
- Trim and Fascia: They can also be
cut into trim boards, fascia, and soffits for a durable and
low-maintenance exterior finish.
3. Flooring and Subflooring
Due to their high compressive strength and
dimensional stability, MGO boards are an ideal material for subflooring and
underlayment.
- Subflooring: They can be used as a
solid and stable base for various floor coverings, including tile,
hardwood, vinyl, and carpet.
- Tile Backer Board: MGO boards are
particularly well-suited for use as a backer board for tile installation
in wet areas like showers, tub surrounds, and kitchen floors, as they will
not swell or degrade from water exposure.
- Sound Dampening: They also provide
some sound dampening, which is beneficial for floors in multi-level
buildings.
4. Structural Insulated Panels (SIPs)
MGO boards are a common facing material for
Structural Insulated Panels (SIPs). In this application, a rigid foam
insulation core is sandwiched between two MGO board panels. This creates a
strong, energy-efficient, and fire-resistant building component that can be
used for walls, floors, and roofs.
5. Other Specialized Applications
- Fire Barriers: Because of their
exceptional fire rating, MGO boards are used for fireproof partitions,
fire-rated doors, and to protect structural steel beams and columns.
- Modular and Prefabricated Construction: Their light weight and ease of installation make MGO boards a
popular choice in off-site construction, where building components are
manufactured in a factory and then assembled on-site.
- Decorative and Acoustic Panels: MGO
boards can be painted, plastered, or laminated to create decorative wall
or ceiling panels. They can also be perforated and used as acoustic panels
in theaters, auditoriums, and other spaces where sound control is
important
